John Deere 997 Serial Number Lookup & PIN Location

John Deere 997 Serial Number Lookup, PIN Location, Parts & Year Guide

The John Deere 997 is a commercial diesel zero-turn mower from John Deere’s ZTrak line. Its Product Identification Number, commonly called the PIN or serial number, is the key reference for ordering accurate mower, chassis, electrical and deck parts; identifying production-range changes; confirming the machine’s identity; and checking the correct service information.

This guide covers the John Deere 997 diesel commercial zero-turn mower, not the later Z997R designation. John Deere used closely related model names within its diesel ZTrak range, and parts, manuals, emissions equipment, switches, mower-deck components and service procedures can differ between the 997 and later Z997R production versions. Always confirm the model designation and complete machine PIN before using parts or maintenance information.

A machine decal saying “997” is useful, but it is not always enough for a reliable John Deere 997 parts lookup. The complete PIN, engine identification and mower-deck information help distinguish production changes that may affect the correct component.

Quick Guide: Where to Find the Serial Number on a John Deere 997

Identification number	Location on the John Deere 997	What it is used for
Main machine PIN / serial number	Check the identification tag on the rear-frame area of the zero-turn mower. On John Deere zero-turn mowers, the ID tag is generally positioned above the engine on the frame or beneath the engine area. Confirm the exact position against the applicable 997 operator’s manual or official parts information.	Machine identification, parts lookup, service information, ownership records and safety checks
Engine serial number	Found directly on the diesel engine, on an engine-mounted identification label or marked engine identification area. The precise position should be confirmed against the engine documentation.	Engine-specific repair parts, fuel-system work and engine service information
Transmission / drivetrain identification	Check the transmission or hydrostatic-drive components for their own manufacturer or component identification markings where drivetrain service is required.	Drivetrain-specific repair information and component identification
Mower-deck identification	Varies by deck and accessory. Inspect the deck for its own identification label or product information.	Deck parts identification, blade selection and fitment confirmation

On the John Deere 997, the main Product Identification Number (PIN) is located in the rear-frame and engine-area identification zone used on John Deere zero-turn mowers. Confirm the exact tag position against the operator’s manual and official parts information for the machine’s production range before relying on a parts listing.

If you are in a hurry:

Park the machine safely on level ground, stop the engine and remove the key.

Check the rear chassis and engine-frame area for the identification plate.

Look for “PIN,” “Product Identification Number,” “Product ID” or “Serial Number.”

Use a torch and clean surrounding dirt gently with a brush and cloth if needed.

Record every character exactly as shown before ordering parts or contacting a dealer.

Main Product Identification Number Location on the John Deere 997

Exact position on the machine

The John Deere 997 is a rear-engine commercial zero-turn mower. Its main machine identification information is associated with the rear portion of the chassis rather than the front caster-wheel area used on some lawn tractors.

Begin at the rear of the mower and inspect the frame around the engine compartment. On John Deere zero-turn mowers, the machine identification tag may be positioned on the frame above the engine or in the area beneath the engine. Access can be limited by accumulated grass debris, grease, dirt, attachments, guards or the mower’s parked position.

Do not confuse the following numbers:

The main machine PIN or serial number
The engine serial number
The mower-deck identification number
A hydraulic-drive or transmission component number
A casting number on a frame, spindle, engine or gearbox component
A dealer inventory number or aftermarket security marking

If the tag is not visible from the rear, consult the operator’s manual that matches the machine’s PIN range. A John Deere dealer can also help identify the correct location from the model and available machine details.

What the PIN plate looks like

The identification tag normally provides the model designation and the machine’s unique Product Identification Number or serial number. Exact plate design, wording, material and mounting details should be confirmed for the individual mower because identification labels can vary with production period, market and replacement-frame history.

On an older commercial mower, the tag may be difficult to read because of:

Dirt and compacted grass debris
Oil, fuel residue or cleaning-product build-up
Corrosion or oxidation
Fading caused by sunlight and weather
Paint overspray from previous repairs
Physical damage caused by impact, heat or abrasion

Tips for old, dirty or painted machines

Use careful cleaning methods that preserve the original identification information.

Brush away loose grass, soil and debris around the tag.
Wipe the area with a clean cloth.
Use a mild degreaser sparingly if oily contamination prevents reading the number.
Photograph the tag before and after cleaning.
Record every letter and number, including any leading zeroes.
Compare the copied PIN with service records, proof of purchase and dealer paperwork.

Do not use a grinder, wire wheel, aggressive abrasive pad or chemical stripper on an identification plate. Do not restamp, alter or create a replacement identification plate.

Engine Serial Number on the John Deere 997

The engine serial number is separate from the John Deere 997 machine PIN. The machine PIN identifies the mower as a complete unit, while the engine number identifies the engine installed in it.

This distinction matters when ordering engine-related parts or requesting technical information for:

Engine overhaul parts
Fuel-system components
Starter and charging-system parts
Cooling-system components
Belts and engine-mounted accessories
Engine electrical components
Fuel filters and air filters
Emissions-related components where fitted

Engine serial-number location

The engine identification number is located directly on the engine, normally on an engine-mounted label or designated marked area. The exact position can vary by engine version and production range, so confirm the location through the engine documentation, official John Deere parts catalogue or a John Deere dealer.

Do not assume that the engine number will match the mower’s main PIN. They are separate identifiers serving different purposes.

Engine variants and parts implications

The John Deere 997 is associated with a diesel engine application, but engine-related parts should never be ordered from the mower model alone. Identify the engine model and engine serial number before ordering engine-specific components.

Different engine versions or emissions configurations can affect:

Fuel-filter specification
Air-intake components
Exhaust and muffler assemblies
Electrical components
Cooling-system parts
Engine control components
Engine service procedures

A correct John Deere 997 parts lookup starts with the machine PIN for chassis and mower components, then uses engine identification for engine-specific parts.

How to Read a John Deere 997 Serial Number

Copy the complete machine PIN exactly as it appears on the identification tag. A missing digit, transposed number or incorrect letter can lead to the wrong parts catalogue section, incorrect production-range selection or a failed dealer lookup.

A John Deere machine PIN may contain information used by John Deere systems to identify the machine family, production sequence, configuration or manufacturing details. However, owners should not assume that every character can be decoded using generic online charts.

PIN structure

John Deere’s publicly available documentation does not clearly confirm one universal character-by-character decoding rule for every John Deere 997 production version. Some character meanings may be internal to John Deere and dealer systems and should not be guessed.

text

[MODEL CODE]-[PRODUCTION CODE]-[SEQUENCE NUMBER]

Illustrative format only — this is not a real John Deere 997 serial number and should not be used to identify a machine.

What the PIN can tell you

When entered correctly into a dealer system or PIN-capable parts catalogue, the number can help with:

Identifying the individual mower
Selecting the relevant parts-catalogue production range
Identifying applicable parts notes and serial breaks
Helping a dealer determine production details
Matching service information to the machine
Checking machine-specific safety actions where applicable
Confirming that the paperwork and mower identify the same machine

What the PIN cannot tell you on its own

A PIN is important, but it does not independently prove:

The exact calendar year without a verified lookup
The mower’s complete original specification
The original supplying dealer
Full service history
Current legal ownership
Whether the engine, deck or other major components have been changed
Whether a machine is stolen
Whether finance is outstanding
Whether maintenance has been completed correctly

Use the PIN as one part of a wider identity and condition check.

Finding the Year of Your John Deere 997 from the Serial Number

A John Deere 997 serial number should not be matched to a generic John Deere year chart unless that chart clearly identifies the exact 997 diesel zero-turn mower and the applicable market. Generic serial-number lists often mix tractors, lawn equipment, construction equipment and later ZTrak models that use different numbering systems.

Publicly available model-specific serial-number year ranges should be confirmed against the relevant John Deere manual, official parts catalogue or dealer PIN lookup before treating a production year as definite.

Use this process to establish the machine’s production period:

Copy the full machine PIN exactly.
Check the applicable official John Deere 997 operator’s manual or parts catalogue for production-range references.
Ask a John Deere dealer to search the complete PIN.
Compare the result with original sales documents, service records, labels, decals and the mower-deck configuration.
Be cautious with online serial-year charts that do not clearly match the John Deere 997 diesel commercial mower.

A dealer PIN lookup is normally the most dependable route when a buyer, seller, restorer or parts purchaser needs a production-period confirmation.

Using Your John Deere 997 Serial Number to Order the Right Parts

The “997” decal identifies the mower model, but it does not always identify the exact version of every component. Parts can change during production because of engineering updates, supplier changes, safety revisions, emissions differences or mower-deck revisions.

The correct ordering process is especially important for electrical switches, engine-related components, deck spindles, pulleys, idlers, belts, control cables and other parts that may have serial-range notes.

Understanding serial breaks

A serial break is a point in production where John Deere changed a part, system or design. The same model may therefore use one component before a particular serial number and another component at or after that number.

Common parts-catalogue wording includes:

Serial number below: Use this part only before the stated PIN or serial number.
Serial number and above: Use this part from the stated PIN or serial number onward.
Before PIN: A part applies to earlier production.
After PIN: A part applies to later production.
Early production: The part fits an earlier design.
Late production: The part fits a revised design.
With or without option: Fitment depends on an original factory or dealer-installed configuration.

Known serial-range implications

John Deere parts information for the closely related diesel ZTrak product line shows that some components can change at defined serial-number points. For example, electrical and mower-deck components may use early- and later-production part applications. The exact applicability for a John Deere 997 must be checked against the correct parts catalogue for its complete machine PIN.

Read every serial-range note in the official parts diagram. Do not order a component simply because it appears under a listing headed “John Deere 997.”

Ordering parts correctly

Photograph and record the complete machine PIN.
Confirm the exact John Deere 997 designation on the machine identification tag.
Identify the engine model and engine serial number for all engine-related parts.
Use the official John Deere parts catalogue where possible.
Read every “before,” “after,” “serial number below” and “serial number and above” note.
Compare the old component, its visible features and any numbers on it with the parts diagram.
Ask a John Deere dealer or knowledgeable supplier to confirm uncertain parts before ordering.

Aftermarket catalogues can group several production versions under one model name. Treat an aftermarket cross-reference as a starting point, not final proof of fitment.

Maintenance and Service Differences by Serial Range on the John Deere 997

Basic mower care remains important throughout the 997’s life: keep the cooling and engine areas clean, inspect belts and blades, maintain the mower deck, monitor fluids and follow the operator’s manual. However, maintenance parts and service procedures can vary by serial range, engine version and installed mower deck.

The machine PIN helps ensure that the correct manual and parts information is used for:

Engine oil and fuel-service parts
Air-cleaner components
Hydraulic-drive service parts
Electrical switches and wiring components
Drive belts and deck belts
Spindles, pulleys and idlers
Battery and starting-system components
Mower-deck blades and mulching equipment

Use maintenance information that matches the exact machine PIN range. Confirm the engine model and engine serial number before ordering engine filters, fuel-system parts, electrical components or overhaul items.

Do not rely on a maintenance kit advertised only for “John Deere 997” unless the seller confirms the engine application, serial range and deck configuration.

Attachment Compatibility for the John Deere 997 by Serial Number

The John Deere 997 is a commercial zero-turn mower, so mower-deck configuration and turf-care accessories are more relevant than tractor implements such as loaders, backhoes or three-point-hitch equipment.

Attachment and accessory fitment can depend on more than the mower model decal. Before purchasing a deck-related accessory or replacement assembly, confirm:

The complete machine PIN
Mower-deck size and identification
Deck serial number or deck product information where available
Deck mounting arrangement
Belt-routing arrangement
Spindle and pulley configuration
Required brackets, guards and hardware
Whether the mower has an early or later production design
Regional-market specification where relevant

Mower-deck checks

Diesel commercial ZTrak equipment has been offered with different deck configurations, and deck parts may vary with deck width and production range. A 60-inch deck component should not be assumed to fit a 72-inch deck, even where both applications appear under the same mower family.

Before ordering a mower-deck part or accessory:

Record the mower PIN.
Identify the deck width and deck information.
Compare the deck diagram with the actual mower.
Confirm belt, spindle, pulley and blade arrangement.
Provide both machine and deck information to a John Deere dealer if fitment remains uncertain.

Attachment fitment should be confirmed using both the machine PIN and the attachment identification number.

Checking Recalls and Safety Notices Using Your John Deere 997 PIN

Safety recalls, campaigns and service actions can apply only to particular production ranges, installed components or configurations. Do not assume that a safety notice applies to every John Deere 997, or that an older mower has already received all applicable work.

Use this process:

Record the complete machine PIN.
Contact a John Deere dealer and request a check for open safety campaigns or recall actions.
Check official John Deere safety or recall information for the applicable market.
Keep a photograph and written record of the PIN with ownership and service records.

A dealer can use the complete machine PIN to check whether a particular action applies to that mower.

Using the John Deere 997 Serial Number When Buying or Selling

Checks for buyers

A complete PIN check is one of the most useful steps when buying a used diesel zero-turn mower. It helps confirm that the machine, paperwork, parts information and claimed configuration all relate to the same unit.

Use this checklist:

Check that the PIN plate matches available paperwork.
Confirm that the model designation identifies a John Deere 997 diesel commercial zero-turn mower.
Look for evidence of plate damage, removal, unusual rivets, mismatched paint or altered characters.
Confirm that the seller is not confusing an engine, deck or drivetrain number with the machine PIN.
Use the PIN to check applicable parts ranges and possible safety actions.
Confirm mower-deck identification and deck size before valuing included equipment.
Compare hours, condition, service records and wear with the seller’s description.
Be cautious if the seller cannot explain missing or inconsistent identification information.
Pause the purchase if there is a serious identity discrepancy.

Advice for sellers

A clear listing helps legitimate buyers assess a used John Deere 997 properly. Include the correct model designation, hours, mower-deck information, service history and clear general photographs of the machine.

Avoid posting a high-resolution public image of the entire PIN plate. Share the complete number privately with a serious buyer, John Deere dealer, insurer, lender or parts supplier where appropriate.

What If You Cannot Find or Read the Serial Number on Your John Deere 997?

Plate is dirty, painted over or faded

Clean the surrounding area carefully using a soft brush, cloth and suitable mild cleaner. Use strong lighting and take several photographs from different angles. Record visible characters without guessing at missing characters.

If paint covers the tag, do not use abrasive tools or harsh stripping methods that could destroy the identification information.

Plate is corroded or damaged

Write down every readable character and compare it with original paperwork, dealer invoices, service records and equipment-registration documents. A John Deere dealer may be able to help determine whether the visible information corresponds with a valid mower record.

Do not alter the plate, attempt to deepen characters or apply a newly made identification tag.

Plate is missing

Check for legitimate documentation, dealer service records and separately marked major components, but do not treat an engine or mower-deck number as a replacement for the machine PIN.

If the identification plate is missing, unreadable or suspicious, contact a John Deere dealer. Where ownership, theft, insurance, financing or registration may be relevant, contact the appropriate local authority before buying, selling or registering the machine.

PIN does not match paperwork

A mismatch can result from:

A data-entry error
Incorrect paperwork
An engine or mower-deck number being mistaken for the machine PIN
A replacement component
An incomplete or inaccurate sales listing
A more serious ownership or identity issue

Resolve the discrepancy through a John Deere dealer and, where appropriate, the relevant authority before completing a purchase, sale or registration.

John Deere 997 Serial Number FAQ

Where is the serial number on a John Deere 997?

The main John Deere 997 machine identification number is associated with the rear frame and engine-area identification zone used on John Deere zero-turn mowers. Inspect the frame above the engine and the area beneath the engine. If it is not visible, use the operator’s manual or ask a John Deere dealer to confirm the exact location for the mower’s PIN range.

What does the serial number on my John Deere 997 identify?

The machine serial number, also called the Product Identification Number or PIN, identifies the individual mower. It helps a dealer or parts system select relevant production information, parts-catalogue notes and applicable safety checks. It is more reliable than relying on the “997” model decal alone when a component changed during production.

Is the John Deere 997 serial number the same as a VIN?

The John Deere 997 PIN serves a similar practical purpose to a vehicle identification number because it identifies an individual machine. However, it should not automatically be treated as a road-vehicle VIN or decoded using generic automotive VIN tools. Use John Deere parts information or a dealer PIN lookup for machine-specific interpretation.

Is the Product Identification Number the same as the serial number?

In normal owner and parts use, the terms are often used interchangeably for the mower’s main identification number. The important point is to provide the complete machine PIN from the mower identification tag, not only the model decal, engine number, deck number or a component casting number.

Can I find the year of my John Deere 997 from the serial number?

A complete PIN may allow a John Deere dealer to identify the mower’s production details. Do not depend on a generic online year chart unless it clearly applies to the John Deere 997 diesel commercial zero-turn mower and the relevant market. Compare a dealer lookup with original paperwork, manuals, decals and configuration details.

Are official serial-number year charts available for the John Deere 997?

Use only official model-specific manuals, parts catalogues or dealer information when attempting to connect a John Deere 997 PIN with a production period. A chart made for tractors, later Z997R models or another John Deere mower can give a misleading result. A dealer PIN lookup is usually the safest confirmation route.

How accurate are online John Deere 997 serial-number year charts?

Accuracy varies widely. Some online charts apply only to a different equipment category, a different market or another John Deere numbering system. Treat an online chart as unverified unless it identifies the precise John Deere 997 mower, the applicable serial range and the market. Confirm important buying, insurance or parts decisions through a dealer.

What is the difference between the machine PIN and engine serial number?

The machine PIN identifies the complete John Deere 997 mower. The engine serial number identifies the diesel engine itself. Use the machine PIN for chassis, mower-deck, controls and machine-level parts information. Use the engine model and serial number for engine-specific repair parts, fuel-system parts and engine service procedures.

Where is the engine serial number on a John Deere 997?

The engine serial number is located directly on the engine, typically on an engine-mounted identification label or marked engine identification area. Its exact position can vary by engine version and production range. Consult the correct engine documentation, John Deere parts catalogue or dealer if the number is not immediately visible.

Do I need the engine number or the machine PIN to order parts?

For most mower chassis, deck, steering, electrical and control parts, start with the machine PIN. For engine overhaul parts, fuel-system components, engine electrical parts or engine-mounted accessories, provide the engine model and engine serial number as well. Supplying both identifiers reduces the risk of receiving an incorrect part.

Why does the parts catalogue ask for a serial-number range?

The catalogue uses serial ranges to distinguish early and late production designs. A component may have changed during the 997’s production run, meaning a part can fit machines before a stated number but not machines after it. Always read the serial-range wording beside the part, not only the model heading.

What is a serial break on a John Deere 997?

A serial break is the production point at which John Deere changed a part, design or system. It may affect electrical switches, deck components, pulleys, spindles, belts or other assemblies. A serial break does not necessarily mean that the mower is defective; it simply means parts identification must follow the applicable production range.

Which John Deere 997 parts are most likely to change by serial range?

Items that commonly require close serial-range checking include mower-deck spindles, pulleys, idlers, belts, electrical switches, control components, engine-related service items and configuration-specific assemblies. The exact items depend on the production range and installed deck. Use the official parts catalogue and compare the actual component before ordering.

Does maintenance differ by serial number on a John Deere 997?

Maintenance principles remain similar, but the correct filters, belts, electrical items, deck components and engine-related parts may depend on PIN range, engine version and mower-deck configuration. Follow the operator’s manual and parts information that matches the complete machine PIN. Confirm engine identification before ordering engine-specific maintenance components.

Can filters change by serial number or engine version?

Yes. Engine-related filters and service items can vary by engine version, emissions configuration and production range. Do not order a filter kit solely from the mower’s 997 decal. Provide the machine PIN plus the engine model and engine serial number when the part is connected with the diesel engine.

How do I use a John Deere parts catalogue with my 997 PIN?

Enter the model or complete PIN where the official parts system allows it. Then select the correct machine and review the catalogue notes carefully. Check every serial-range qualifier, identify the relevant mower deck or engine section and compare the diagram with the component on your mower. Ask a dealer to confirm any uncertain selection before ordering.

Can a John Deere dealer identify build details from the PIN?

A John Deere dealer can use the complete PIN to access information available through John Deere systems for that machine. The amount of detail available can vary, but a dealer lookup is useful for confirming the correct production range, parts information and applicable safety actions. Bring clear photographs and all available paperwork if the plate is difficult to read.

Can I check recalls or safety notices using my John Deere 997 PIN?

Yes. Record the complete machine PIN and ask a John Deere dealer to check for open safety campaigns, recall actions or applicable service information. Such actions may apply only to certain production ranges or component configurations. Keep the PIN with your ownership and maintenance records so it is available when needed.

Avoid publishing a high-resolution image that clearly shows the complete PIN plate. A serious buyer, dealer, insurer or parts supplier may reasonably need the full number, but it is better to share it privately. For a public advert, you can show the model, hours, general condition and partial identification details if appropriate.

What should I do if the serial plate is missing?

Do not create, stamp or install a homemade replacement plate. Gather original paperwork, dealer service records, proof of purchase and any legitimate component identification information. Contact a John Deere dealer for guidance. If ownership, theft, insurance, finance or registration is involved, contact the appropriate authority before proceeding.

How can I tell whether a serial plate has been tampered with?

Look for unusual rivets, inconsistent mounting, altered characters, disturbed paint, scratches around the plate, mismatched numbers on paperwork or signs that the plate has been removed and refitted. None of these signs alone proves wrongdoing, but a serious discrepancy should be resolved through a John Deere dealer and, where necessary, the appropriate authority.

Can I legally replace a damaged identification plate?

Do not replace, restamp or reproduce a John Deere 997 identification plate yourself. Rules differ by location and by the reason the identification is needed. If a plate is damaged or unreadable, contact a John Deere dealer and, where ownership, insurance, theft or registration is involved, seek guidance from the appropriate authority.

Why does the serial number not match my paperwork?

The discrepancy may be a typing error, incorrect paperwork, an engine or deck number mistaken for the machine PIN, or a record associated with another mower. It can also indicate a more serious issue. Stop and resolve the difference before a purchase or sale, using a John Deere dealer and relevant authorities if needed.

Do attachments for a John Deere 997 depend on serial number?

They can. Mower-deck components, mulching equipment, blade options, belt arrangements and mounting hardware may depend on deck width, production range and configuration. Confirm the machine PIN and deck identification before buying an attachment or deck-related component. Never assume that parts from another 997 or ZTrak model will fit without verification.

Which mower decks fit a John Deere 997?

Deck fitment must be confirmed using the mower’s complete PIN, deck information and official John Deere parts or attachment documentation. Do not assume that every commercial ZTrak deck fits every 997 mower. Deck width, mounting arrangement, belt routing, pulley design and serial-range changes can affect compatibility.

Will an attachment from another John Deere model fit my machine?

Not necessarily. Even a visually similar John Deere commercial mower may use different deck mounts, belts, pulleys, electrical connections or safety equipment. Verify fitment with the machine PIN and attachment identification number through official John Deere parts information or a dealer before purchasing.

Can I decode every character in my John Deere 997 serial number?

Do not assume that every character has a publicly usable meaning. John Deere dealer systems may interpret production and configuration information that is not reliably decoded through generic online charts. Copy the PIN exactly and ask a dealer for confirmation if you need production, configuration or parts-range information.

Does the serial number show where my John Deere 997 was built?

The complete PIN may contain information used internally by John Deere, but owners should not guess a factory or country from individual characters without model-specific confirmation. If manufacturing information is important for documentation, resale or import purposes, ask a John Deere dealer to check the complete PIN.

How should I record and store my John Deere 997 PIN?

Photograph the identification tag clearly, write the full number in the operator’s manual and store a second copy with insurance, service and ownership records. Record the engine serial number and mower-deck information separately. Keep copies in a secure location and avoid publicly posting a fully readable identification plate.

Can I still get parts for an early John Deere 997?

Availability depends on the component and production range. Start with the complete machine PIN, then use the official parts catalogue to identify the original part and any current replacement information. A John Deere dealer can help determine whether the part remains available, has been superseded or requires an alternative repair approach.

How can I identify my machine if the John Deere 997 decals are missing?

Look for the main Product Identification Number tag, engine identification and mower-deck information. Do not identify the mower solely from paint colour, seat style, deck shape or engine appearance. A John Deere dealer can use the complete PIN to help confirm the model and applicable production information.

Does the serial number affect resale value?

The PIN does not create value by itself, but a clear, legible and matching identification record can increase buyer confidence. A mower with a readable PIN, consistent paperwork, documented hours, service history and confirmed deck configuration is easier to evaluate. Missing or inconsistent identification can reduce buyer confidence and complicate a sale.

Service information can be machine- and production-range-specific. Ask a John Deere dealer to check the complete PIN for applicable service information, technical updates and open safety actions. Do not rely on a bulletin intended for a later Z997R or another John Deere diesel mower without confirming it applies to the exact 997.

Who should I contact if I am still unsure about my John Deere 997 serial number?

Contact a John Deere dealer with clear photographs of the mower, identification tag, engine label, mower deck and available paperwork. Provide the complete PIN exactly as recorded. If the issue involves missing identification, ownership concerns, suspected theft, insurance or registration, contact the appropriate local authority as well.
