John Deere 345 Serial Number Lookup, PIN Location, Parts & Year Guide
The John Deere 345 is a liquid-cooled lawn and garden tractor sold primarily in North America. It is distinct from the later GX345 garden tractor, which has a different model designation, PIN range, equipment specification and parts information. This guide covers the John Deere 345 lawn and garden tractor, not the GX345.
The machine Product Identification Number, commonly called the PIN or serial number, is essential when ordering parts, selecting the correct manual, identifying serial-range changes and checking the identity of a used tractor. The engine serial number and mower-deck serial number matter separately, especially when buying engine components, belts, blades, deck parts or attachment-related hardware.
And See:
A model decal saying “345” is useful, but it is not enough for reliable parts ordering. John Deere made production changes during the 345’s life, and the correct part can depend on the tractor serial number, engine identification, mower-deck serial number and installed options.
Important: This article covers the John Deere 345 lawn and garden tractor with the Kawasaki FD611V liquid-cooled V-twin engine. Do not use 345 information for a GX345, a later Z345 zero-turn mower, or another John Deere product carrying a similar number.

Quick Guide: Where to Find the Serial Number on a John Deere 345
On the John Deere 345, the main Product Identification Number (PIN) is located at the rear of the tractor above the drawbar area. Check the identification label carefully and record the complete number exactly as shown.
If you are in a hurry:
Park the machine safely on level ground, stop the engine and remove the key.
Check the rear drawbar area for the identification label.
Look for “PIN,” “Product Identification Number,” “Product ID” or “Serial Number.”
Use a torch and clean the surrounding dirt gently with a brush and cloth if needed.
Record every character exactly, including leading zeroes.
Main Product Identification Number Location on the John Deere 345
Exact position on the machine
The main John Deere 345 identification label is located on the rear of the tractor above the drawbar. The drawbar is the rear towing point below the back of the tractor, so inspect the fixed rear chassis area immediately above it rather than looking only at the hood, dashboard or engine compartment.
The label can be difficult to spot on an older tractor because the rear chassis area is exposed to grass clippings, dust, mud, corrosion, sun fading and previous repainting. A rear attachment, hitch equipment, weight bracket or accumulated debris may also make the area less convenient to inspect.
The number on this label is the machine’s primary identification number. Use it whenever ordering chassis, electrical, steering, transmission, hydraulic-lift, fuel-system or model-specific service parts.
What the PIN plate looks like
The identification label carries the machine’s Product Identification Number and model-identification information. Its appearance can vary with age, condition and production range, so do not rely on label colour, material, shape or mounting style alone to confirm a tractor’s identity.
Look for a label that appears original to the rear chassis area and that includes the model designation and an identification number. The PIN should be readable, consistent and free from signs of obvious alteration.
Tips for old, dirty or painted machines
Use careful cleaning methods that preserve the identification label and its characters.
-
Brush away loose dirt, dry grass and debris with a soft brush.
-
Use a clean cloth and mild degreaser if oily residue covers the label.
-
Photograph the label before cleaning, then take additional close photographs afterward.
-
Use angled lighting or a torch to make faded characters easier to read.
-
Record every letter and number exactly as shown, including leading zeroes.
-
Compare the number on the plate with the seller’s paperwork, service records and parts receipts.
Do not use a grinder, wire wheel, aggressive abrasive, sanding disc or harsh scraping tool on an identification plate. Do not restamp, alter, recreate or fit a replacement identification plate yourself.
If the machine identification plate is missing, unreadable or suspicious, contact a John Deere dealer. Where theft, ownership, insurance or registration may be relevant, also contact the appropriate local authority before buying, selling or transferring the machine.
Engine Serial Number on the John Deere 345
The John Deere 345 uses a Kawasaki FD611V liquid-cooled V-twin gasoline engine. The engine serial number is separate from the tractor PIN and is important when ordering engine-specific parts or following engine repair procedures.
The machine PIN identifies the tractor. The engine number identifies the engine installed in it. A tractor may retain its original engine, but an engine can also be replaced during the life of an older garden tractor. For that reason, never assume that the engine serial number and machine PIN will provide the same information.
Engine serial-number location
The Kawasaki FD611V engine serial number is found on an engine-mounted identification label or identification area. The exact position can vary by engine version and production range, so confirm the engine model and serial-number location against the applicable Kawasaki engine documentation, official John Deere parts catalogue or John Deere dealer information before ordering engine-specific components.
Inspect the engine only with the tractor parked safely, engine stopped and key removed. Allow the engine and cooling system to cool fully before working around the engine compartment.
Why the engine number matters
The engine model and serial number can be needed for:
-
Engine overhaul parts
-
Carburetion or fuel-system components
-
Ignition components
-
Cooling-system parts
-
Belts and pulleys
-
Electrical charging and starting components
-
Gaskets, seals and oil-system parts
-
Engine-specific service procedures
The John Deere 345’s Kawasaki FD611V is a 20 hp, liquid-cooled, four-cycle V-twin. It uses a replaceable full-flow oil filter and a paper air-cleaner element with a foam precleaner.
How to Read a John Deere 345 Serial Number
Copy the complete John Deere 345 PIN exactly as it appears on the machine. Do not omit leading zeroes, substitute similar-looking letters and numbers, or rely on a partial number from an advertisement, old receipt or handwritten note.
The PIN is the best starting point for identifying the individual tractor and matching it to the correct John Deere parts information. A dealer can use the complete number to help identify the production range and applicable parts listings.
PIN structure
John Deere’s publicly available documentation for the 345 identifies applicable operator-manual ranges, including tractors from PIN 070001 onward, but it does not provide a complete consumer-facing character-by-character decoding chart for every John Deere 345 PIN.
Some PIN characters may be used within John Deere systems to identify manufacturing, configuration or sequence information. Do not guess the meaning of individual characters from generic online PIN decoders.
[MODEL CODE]-[PRODUCTION CODE]-[SEQUENCE NUMBER]Illustrative format only — this is not a real John Deere 345 serial number and should not be used to identify a machine.
What the PIN can tell you
A complete, accurate PIN can help you:
-
Identify the individual John Deere 345 tractor
-
Select the appropriate serial-range section of a parts catalogue
-
Match the tractor to the correct operator’s or technical manual
-
Help a dealer identify the production range or configuration
-
Check whether safety actions may apply to the machine
-
Confirm whether a mower deck, maintenance kit or replacement component matches the relevant production range
What the PIN cannot tell you on its own
A PIN should not be treated as complete proof of a tractor’s history or legal status. By itself, it does not independently prove:
-
Exact calendar year
-
Full original equipment specification
-
Original dealer
-
Complete maintenance history
-
Current legal ownership
-
Whether major components have been replaced
-
Whether a machine is stolen
-
Whether finance is outstanding
-
Whether a seller’s paperwork is accurate
Finding the Year of Your John Deere 345 from the Serial Number
The John Deere 345 was produced during the late 1990s and early 2000s. Common serial-number reference material associates the model with production beginning at serial number 010001 in 1995, progressing through 095001 for 2001. However, production-year references should be treated as a guide rather than as final proof of a machine’s exact build date, market specification or original sale year.
Use the full machine PIN and original records for a more reliable identification result. Dealer records, manuals, component labels and original purchase documents can help confirm the production period.
These figures are production-range reference points, not a substitute for a full dealer PIN lookup. A tractor could have been sold after its production year, and components may have been replaced during its working life.
How to confirm the production period
-
Copy the full PIN exactly from the rear identification label.
-
Check the official model-specific operator’s manual, parts catalogue or verified serial-range table.
-
Ask a John Deere dealer to search the complete PIN.
-
Compare the result with original invoices, labels, decals and installed configuration features.
-
Be cautious with generic online serial-year charts that do not clearly identify the John Deere 345 lawn and garden tractor.
Using Your John Deere 345 Serial Number to Order the Right Parts
The “345” decal alone is not always enough for an accurate John Deere parts lookup. Production changes can affect belts, fuel-system parts, ignition-related parts, maintenance kits, mower-deck components and other replacement items.
John Deere 345 parts information includes serial-range distinctions. For example, some maintenance and drive components differ before and after specific tractor serial numbers. The exact machine PIN is therefore an important part of every parts order.
Understanding serial breaks
A serial break is a point in production where John Deere changed a part, system, design or supplier. The changed component may not fit, function or connect correctly on machines built before or after that point.
Common parts-catalogue wording includes:
-
Serial number below: Applies only before the stated serial number.
-
Serial number and above: Applies from the listed serial number onward.
-
Before PIN: Applies to earlier production.
-
After PIN: Applies to later production.
-
Early production: A component used on earlier tractors in the model run.
-
Late production: A component used after a production change.
-
With or without option: Fitment depends on installed equipment as well as serial range.
Known serial breaks on the John Deere 345
Mower decks have their own serial numbers and may have separate serial-break information. A 345 tractor PIN does not replace the need to identify the mower-deck model and serial number.
Ordering parts correctly
-
Photograph and record the complete machine PIN.
-
Confirm that the rear identification label identifies the tractor as a John Deere 345.
-
Identify the Kawasaki FD611V engine model and record the engine serial number for engine-related parts.
-
Record the mower-deck model and deck serial number before ordering blades, belts, spindles, wheels or deck hardware.
-
Use the official John Deere parts catalogue where possible.
-
Read every “before” and “after” serial-range note.
-
Compare the old part number and visible component with the parts diagram.
-
Ask a John Deere dealer or knowledgeable supplier to confirm uncertain parts before ordering.
Aftermarket catalogues sometimes group early and late tractors under one model heading. That can be convenient for browsing, but it can lead to an incorrect order when the part changed by serial range.
Maintenance and Service Differences by Serial Range on the John Deere 345
The John Deere 345 is equipped with a Kawasaki FD611V liquid-cooled engine and a Kanzaki hydrostatic transaxle. The tractor’s engine, cooling system, transmission and mower deck should be serviced using information that matches the actual tractor and attachment serial numbers.
For John Deere 345 tractors covered by the later operator-manual range, the published capacities include 2.0 qt of engine oil with filter, 4.7 qt of transmission oil with filter and 3.3 qt of coolant-system capacity. Use the correct manual and machine serial range before servicing, especially if the tractor has been modified, repaired with replacement components or fitted with a non-original engine.
The correct lubricant requirements are also important. John Deere specifies Low Viscosity HY-GARD fluid meeting J20D for the transmission and recommends the appropriate John Deere engine oil and coolant products for the 345’s engine and cooling system.
Parts and maintenance items that can vary
Serial range, deck configuration and engine details can affect selection of:
-
Traction-drive belts
-
Fuel caps and fuel-system components
-
Home maintenance kits
-
Spark plugs and engine service parts
-
Mower-deck belts
-
Mower blades
-
Gauge wheels and deck hardware
-
Attachment drive components
-
Engine-specific replacement parts
Use the operator’s manual and official parts information that matches the machine’s exact PIN range. Confirm mower-deck and engine identification separately rather than assuming every installed component was supplied with the tractor when new.
Attachment Compatibility for the John Deere 345 by Serial Number
The John Deere 345 was offered with several mower-deck options, including 38-inch, 44-inch, 48-inch and 54-inch mid-mount mower decks. The 48C and 54-inch mower decks use different secondary deck belts and blades, so identifying the deck model is essential before ordering deck parts.
The 345 was also used with front-mounted seasonal attachments and rear hitch equipment. Attachment fitment can depend on the tractor serial range, attachment serial number, mounting hardware, drive components, lift equipment and installed options.
Verified mower-deck information
The tractor and attachment numbers should always be checked together. A mower deck may have been swapped, rebuilt or fitted from another machine, and the deck serial number can be more important than the tractor model decal when ordering deck-specific components.
Checking other attachments
John Deere 345 tractors may be encountered with front blades, snowblowers, tillers, bagging systems, carts or hitch equipment. Do not assume a used attachment will fit simply because it is painted John Deere green or came from another lawn and garden tractor.
Confirm all of the following before buying an attachment:
-
Complete John Deere 345 machine PIN
-
Attachment model designation
-
Attachment serial number
-
Required mounting hardware
-
Drive-belt or driveshaft arrangement
-
Lift linkage or hydraulic-lift requirements
-
Electrical connections, where fitted
-
Tyre, clearance and ballast requirements
-
Compatibility with the installed mower deck or rear hitch equipment
Provide both the tractor PIN and the attachment identification number to a John Deere dealer before purchasing a used deck, snowblower, blade, tiller or bagging system.
Checking Recalls and Safety Notices Using Your John Deere 345 PIN
Safety campaigns, recall actions and service updates can apply to specific machine PIN ranges, components or configurations. A broad online search cannot confirm whether a particular John Deere 345 has received all applicable safety work.
Use the PIN to obtain a machine-specific check.
-
Record the complete machine PIN from the rear identification label.
-
Contact a John Deere dealer and request a check for open safety campaigns, recalls or applicable service actions.
-
Check official John Deere safety information for the market in which the tractor was sold and used.
-
Keep a photograph and written record of the PIN with ownership, insurance and service records.
If the tractor has an unknown history, ask the dealer to check the PIN before investing in major repairs or attachments.
Using the John Deere 345 Serial Number When Buying or Selling
A complete, readable PIN gives buyers and sellers a better way to identify the tractor accurately. It also helps establish whether the tractor, engine, mower deck and paperwork appear consistent.
Checks for buyers
-
Check that the rear PIN label matches available paperwork.
-
Confirm that the tractor is a John Deere 345, not a GX345 or another similar-looking model.
-
Look for signs of damage, removal, unusual rivets, mismatched paint, altered characters or a replacement label.
-
Record the engine model and engine serial number separately.
-
Check the mower-deck model and deck serial number rather than assuming the deck is original.
-
Use the PIN to verify parts ranges, attachment suitability and possible safety actions.
-
Check whether engine, transmission or attachment numbers are being confused with the machine PIN.
-
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 should identify the tractor as a John Deere 345 lawn and garden tractor and should state the installed deck size, known attachments, hour-meter reading and service history. Clear photographs of the overall machine, deck identification and maintenance condition can help legitimate buyers assess the tractor.
Avoid publishing a high-resolution image of the complete PIN plate in a public advertisement. Share the complete number privately with a serious buyer, John Deere dealer, insurer or parts supplier when appropriate.
What If You Cannot Find or Read the Serial Number on Your John Deere 345?
Plate is dirty, painted over or faded
Start with gentle cleaning, strong lighting and close photographs. Clean loose dirt with a soft brush, then use a cloth and mild degreaser where suitable. Record every visible character, even if the complete number cannot yet be read.
Plate is corroded or damaged
Record each readable character and compare it with original sales documents, service invoices and dealer records. A John Deere dealer may be able to help interpret partial information when it is supported by legitimate records.
Plate is missing
Check for legitimate alternative identification points on major components, including the engine, mower deck and transaxle. Review original ownership documents, service records and dealer history where available.
Do not manufacture, restamp, alter or install a replacement identification plate yourself. Contact a John Deere dealer and, where ownership or theft may be relevant, the appropriate local authority.
PIN does not match paperwork
A mismatch can result from a data-entry error, incorrect paperwork, a machine number being confused with an engine or attachment number, or replacement components. It can also indicate a more serious ownership issue.
Resolve the discrepancy through a John Deere dealer and, where appropriate, the relevant authority before buying, selling, insuring or registering the tractor.
John Deere 345 Serial Number FAQ
Where is the serial number on a John Deere 345?
The main John Deere 345 Product Identification Number is located at the rear of the tractor above the drawbar. Inspect the fixed rear chassis area carefully, using a torch if dirt, corrosion or faded markings make the label difficult to read. Record the full number exactly as shown.
What does the serial number on my John Deere 345 identify?
The serial number, also called the Product Identification Number or PIN, identifies the individual tractor. It helps match the tractor to the correct parts-catalogue range, service information and dealer records. It is more reliable than relying only on the “345” model decal.
Is the John Deere 345 serial number the same as a VIN?
The John Deere 345 PIN serves a similar identification purpose to a vehicle VIN, but it should not automatically be treated as an on-road motor-vehicle VIN. The tractor’s PIN identifies the machine for parts, service, ownership records and support programs.
Is the Product Identification Number the same as the serial number?
For practical ownership and parts purposes, the terms are often used interchangeably. John Deere refers to the main machine number as the Product Identification Number, or PIN. Always use the complete number from the rear identification label when communicating with a dealer or supplier.
Can I find the year of my John Deere 345 from the serial number?
A serial-number reference can provide a likely production-year range for many 345 tractors, but it should not be used as sole proof of exact build date or original sale year. Use the complete PIN with a John Deere dealer and compare the result with original records and component labels.
Are official serial-number year charts available for the John Deere 345?
John Deere operator manuals identify applicable PIN ranges, including manuals covering 345 tractors from PIN 070001 onward. For the most accurate production information, ask a John Deere dealer to check the full PIN rather than relying exclusively on a generic serial-year chart.
How accurate are online John Deere 345 serial-number year charts?
Online charts can be useful as a starting point, particularly when they identify production-range starting points. They can still omit market differences, late-year changes, replacement components and documentation limitations. Confirm important buying, restoration and parts decisions with the full machine PIN.
What is the difference between the machine PIN and engine serial number?
The machine PIN identifies the John Deere 345 tractor. The engine serial number identifies the Kawasaki FD611V engine installed in it. Use the machine PIN for tractor, chassis and attachment-related information, and use the engine number for engine-specific repair parts and service procedures.
Where is the engine serial number on a John Deere 345?
The engine number is on an identification label or identification area on the Kawasaki FD611V engine. The exact location can vary by engine version and production range. Check the applicable Kawasaki documentation, John Deere parts catalogue or dealer information before relying on a guessed location.
Do I need the engine number or machine PIN to order parts?
Use the machine PIN for most tractor parts, including chassis, steering, drivetrain, electrical and model-specific components. Use the engine model and engine serial number for engine-related parts. For mower components, also provide the mower-deck model and serial number.
Why does the parts catalogue ask for a serial-number range?
John Deere used serial ranges to identify production changes. A part may differ before or after a stated serial number, even though both tractors are called 345. The serial-range note prevents ordering a component that looks similar but does not fit or function correctly.
What is a serial break on a John Deere 345?
A serial break is a production point where a component or design changed. On the John Deere 345, published maintenance information includes serial-range distinctions for items such as the fuel cap and traction-drive belt. Always read “before” and “after” serial notes in the parts information.
Which John Deere 345 parts are most likely to change by serial range?
Items most likely to require serial-range checking include traction-drive belts, fuel-system components, service kits, electrical components and certain mower or attachment parts. Deck components can also vary by deck model and deck serial number, so identify the mower deck independently.
Does maintenance differ by serial number on a John Deere 345?
Basic servicing remains broadly similar across the model, but the correct maintenance parts and some procedures can vary by serial range, engine details and installed deck. Use the operator’s manual and official parts information that match your tractor’s PIN range before carrying out routine service.
Can filters change by serial number or engine version?
Yes. Engine-related filters and service components should be confirmed against the Kawasaki FD611V engine information and the tractor’s applicable PIN range. Do not order filters solely from a broad online listing if the listing does not distinguish the John Deere 345 from other models or production ranges.
How do I use a John Deere parts catalogue with my 345 PIN?
Start by identifying the tractor as a John Deere 345 and entering or comparing the complete PIN where the catalogue requests it. Read every serial-range note, identify the correct mower deck separately and compare the old component with the illustrated part before ordering.
Can a John Deere dealer identify build details from the PIN?
A John Deere dealer can use the complete machine PIN to help identify the tractor’s production range and applicable parts information. The PIN may also support checks for machine-specific records and safety actions. Bring the full number rather than a partial serial reference.
Can I check recalls or safety notices using my John Deere 345 PIN?
Yes. Record the complete PIN and ask a John Deere dealer to check for applicable recalls, safety campaigns or service actions. Such actions can depend on the individual machine’s production range, configuration or installed components, so a general model search is not enough.
Is it safe to share a John Deere 345 serial number online?
Avoid posting a sharp, full-resolution photograph of the complete PIN plate in a public listing or social-media post. It is usually better to show general machine photographs publicly and provide the complete PIN privately to serious buyers, dealers, insurers or parts suppliers.
What should I do if the serial plate is missing?
Do not make or fit a replacement plate yourself. Record other legitimate identification information, such as engine, deck and transaxle numbers, and gather original paperwork, service invoices and ownership records. Contact a John Deere dealer and, where relevant, the appropriate authority.
How can I tell whether a serial plate has been tampered with?
Warning signs include altered characters, damaged surrounding metal, unusual rivets, mismatched paint, a label that appears newer than the surrounding tractor or numbers that conflict with paperwork. These signs do not prove wrongdoing by themselves, but they justify further investigation before purchase.
Can I legally replace a damaged identification plate?
Do not replace, recreate, restamp or alter an identification plate without proper authority. A John Deere dealer can advise on legitimate identification and documentation procedures. If legal ownership, theft, registration or insurance is involved, contact the relevant local authority or insurer as well.
Why does the serial number not match my paperwork?
The mismatch may be a transcription error, incorrect paperwork, confusion between the tractor PIN and an engine or deck number, or a record created after a component replacement. Resolve the discrepancy before completing a purchase or sale, particularly if the tractor’s ownership history is unclear.
Do attachments for a John Deere 345 depend on serial number?
They can. Fitment can depend on the tractor PIN range, attachment serial number, mounting brackets, drive arrangement, lift linkage and installed options. For mower-deck parts, the deck model and deck serial number are especially important.
Which mower decks fit a John Deere 345?
The John Deere 345 was offered with 38-inch, 44-inch, 48-inch and 54-inch mower-deck options. For accurate replacement parts and fitment confirmation, identify the specific deck model and its serial number. The 48C and 54-inch decks use different secondary belts and blades.
Will an attachment from another John Deere model fit my machine?
Do not assume it will. A John Deere attachment may require different mounting hardware, drive components, lift equipment or electrical connections even when it appears similar. Confirm compatibility using the John Deere 345 PIN and the attachment model and serial number before purchase.
Can I decode every character in my John Deere 345 serial number?
Do not rely on generic character-decoding charts for this model. Some PIN information may be interpreted through John Deere dealer systems and documentation rather than a publicly available decoder. Use the complete PIN for a dealer lookup if you need production or configuration confirmation.
Does the serial number show where my John Deere 345 was built?
The PIN may contain manufacturing or configuration information used within John Deere systems, but publicly available information does not provide a complete character-by-character location decoder for every 345 tractor. Ask a John Deere dealer to check the complete PIN if this detail is important.
How should I record and store my John Deere 345 PIN?
Photograph the rear identification label, engine label and mower-deck tag. Write the numbers down exactly, including leading zeroes, and store the record separately from the tractor. Keep copies with service invoices, insurance documents, ownership records and attachment information.
Can I still get parts for an early John Deere 345?
Many maintenance and wear parts remain identifiable through John Deere parts information, but availability can vary by component and serial range. Use the complete tractor PIN, engine identification and mower-deck number to give a dealer or supplier the best chance of finding the correct item.
How can I identify my machine if the John Deere 345 decals are missing?
Start with the rear Product Identification Number label above the drawbar. Then record the Kawasaki FD611V engine information, mower-deck identification and key configuration details. A John Deere dealer can help distinguish the tractor from similar models using the complete PIN and machine characteristics.
Does the serial number affect resale value?
A clear, readable and consistent PIN can improve buyer confidence because it supports accurate identification, parts availability checks and paperwork verification. A missing, altered or inconsistent number can reduce buyer confidence and may delay or prevent a legitimate sale until the issue is resolved.
Are there known serial-number-related service bulletins for the John Deere 345?
Service actions and technical updates can depend on production range or configuration. Ask a John Deere dealer to check the complete PIN for applicable records rather than relying on unverified bulletin lists or generic online claims.
Who should I contact if I am still unsure about my John Deere 345 serial number?
Contact a John Deere dealer with clear photographs of the rear PIN label, engine identification, mower-deck tag and any available ownership paperwork. For a missing, altered or suspicious identification label, also contact the appropriate authority before buying, selling or registering the tractor.
