John Deere 110 Serial Number Lookup, PIN Location, Parts & Year Guide
The John Deere 110 is one of John Deere’s best-known early lawn and garden tractors. For owners, restorers, mechanics and used-equipment buyers, the tractor serial number is the starting point for identifying the production year, selecting the correct parts catalogue information and avoiding confusion between early and late production machines.
This guide covers the original John Deere 110 lawn and garden tractor produced from 1963 through 1974. These tractors are often called “round-fender” or “square-fender” 110s, depending on production era and body style. The model designation has also appeared on later John Deere lawn tractors and industrial machines, so do not use this guide for an E110 lawn tractor, a later 110 garden tractor, or a John Deere 110 industrial loader/backhoe. Always confirm that the machine is the 1963–1974 garden tractor before using the year chart or parts guidance below.
And See:
The tractor identification number can help establish whether a machine falls into an early or late production range. That matters because body panels, steering parts, mower equipment, electrical components, engine-related parts and other assemblies may not interchange simply because they are listed under “John Deere 110.”

Quick Guide: Where to Find the Serial Number on a John Deere 110
On the John Deere 110, the main Product Identification Number (PIN) is located on the tractor identification plate below the steering column.
If you are in a hurry:
Park the machine safely on level ground, stop the engine and remove the key.
Check below the steering column for the identification plate.
Look for the model designation and serial number.
Use a torch and clean the surrounding dirt gently with a brush and cloth if needed.
The number on the tractor plate is the number normally used to identify the garden tractor itself. Do not confuse it with a casting number, mower-deck number, engine model number or engine serial number.
Main Product Identification Number Location on the John Deere 110
Exact position on the machine
The serial-number plate for the original John Deere 110 garden tractor is located below the steering column. Inspect the area carefully with the tractor parked, engine off and key removed.
The plate may be harder to read on an unrestored machine because this area can accumulate:
-
Dirt and dried grease
-
Old paint from a repaint
-
Surface corrosion
-
Faded or damaged lettering
-
Wear caused by boots, clothing or repeated cleaning
-
Damage from previous repairs or steering-column work
The tractor serial number is especially important on machines that have been repainted or rebuilt. A good restoration may improve appearance, but it does not replace the need to preserve and document the original identification information.
What the identification plate looks like
The exact appearance of the identification plate can vary with age, condition and prior restoration work. Check for a plate that identifies the tractor model and its individual serial number.
A legitimate plate may be dirty, worn or discoloured, but take extra care if it appears recently replaced, does not match the age and condition of the tractor, is attached with unusual hardware, or contains characters that look uneven or altered.
Tips for old, dirty or painted tractors
Use a careful approach when trying to read an old John Deere 110 serial number:
-
Brush away loose dirt and dry debris first.
-
Wipe the area with a clean cloth.
-
Use a mild degreaser only if necessary and avoid soaking electrical components.
-
Photograph the plate before and after cleaning.
-
Record every visible number exactly, including any leading zeroes.
-
Compare the number with the tractor’s paperwork, service records and any previous registration or insurance documents.
Do not use grinders, wire wheels, harsh abrasives or aggressive scraping tools on the plate. Do not restamp, alter or make a replacement serial-number plate.
A serial-number plate is an important identity record. If it is missing, unreadable or appears suspicious, consult a John Deere dealer. If theft, ownership, registration or legal status may be relevant, contact the appropriate local authority before buying, selling or registering the tractor.
Engine Serial Number on the John Deere 110
The engine serial number is separate from the John Deere 110 tractor serial number. The tractor number identifies the garden tractor, while the engine identification is used for engine-specific service work and replacement parts.
This distinction matters when ordering components such as:
-
Engine rebuild parts
-
Carburettor and fuel-system parts
-
Ignition components
-
Starter-generator or charging-system parts
-
Belts and pulleys
-
Cooling-system parts
-
Engine gaskets and seals
-
Electrical components attached to the engine
Engine serial-number location
The original John Deere 110 garden tractor used a Kohler single-cylinder engine, but the exact engine specification and engine identification details should be confirmed from the engine tag and the correct documentation for the individual tractor.
Look for an engine-mounted identification label or stamped engine identification area. The precise location can vary according to engine version, replacement-engine history and previous repairs. Confirm the engine model and engine serial number before ordering engine-specific components.
A rebuilt John Deere 110 may no longer have its original engine. This does not automatically make the tractor incorrect or unusable, but it means the engine parts list may not match the tractor’s production year.
Why the engine number matters
The tractor serial number can identify the John Deere 110 production range, but it does not guarantee that the installed engine remains original. A machine may have a replacement engine, a later carburettor, modified ignition equipment or non-original charging-system parts.
For engine work, record both numbers:
-
The John Deere 110 tractor serial number below the steering column
-
The engine model and engine serial number from the engine itself
How to Read a John Deere 110 Serial Number
Copy the complete serial number exactly as shown on the tractor plate. Avoid relying on a number remembered from a seller’s advert, handwritten note or partial photograph.
The John Deere 110 serial number is primarily useful as a production-sequence identifier. It can be compared with known model-year starting points for the 1963–1974 garden tractor, but it should not be treated as proof of every original component or option.
PIN structure
John Deere used serial-number systems before the modern 17-character Product Identification Number systems found on many later machines. The original 1963–1974 John Deere 110 garden tractor uses a simpler serial-number sequence rather than a modern VIN-style identification format.
Some character meanings, configuration details and manufacturing records may be internal to John Deere systems or historical documentation. Do not attempt to decode characters by applying a modern John Deere PIN chart to an early 110 garden tractor.
What the serial number can tell you
A John Deere 110 serial number can help you:
-
Identify the individual tractor within the original production sequence
-
Estimate the production year using the correct 110 serial-number chart
-
Select the correct early or late parts information
-
Compare the tractor with period-correct bodywork and equipment
-
Help a John Deere dealer or specialist identify the applicable production range
-
Check whether the serial number is consistent with the advertised age of a used tractor
What the serial number cannot tell you on its own
The number alone does not independently prove:
-
The exact calendar date on which the tractor was built
-
The full original equipment specification
-
The original supplying dealer
-
The complete maintenance history
-
The current legal ownership status
-
Whether the engine is original
-
Whether major components have been changed
-
Whether the machine has been stolen
-
Whether finance is outstanding
A serial-number lookup is useful, but it is not a substitute for checking ownership documents, condition, repairs and the identity of the seller.
Finding the Year of Your John Deere 110 from the Serial Number
For the original 1963–1974 John Deere 110 garden tractor, serial-number ranges can be used to identify the production year. These ranges refer to the classic 110 garden tractor and should not be used for later machines carrying the 110 designation.
These figures are best treated as production-year ranges for the original John Deere 110 garden tractor. A serial-number year result should be compared with the tractor’s body style, decals, equipment, original paperwork and known restoration history.
How to check the year
-
Locate the serial-number plate below the steering column.
-
Copy the complete number exactly.
-
Compare it with the original 1963–1974 John Deere 110 serial-number ranges.
-
Check whether the bodywork, hood, fenders, steering arrangement and equipment appear consistent with the estimated year.
-
Ask a John Deere dealer or knowledgeable garden-tractor specialist to help if the number is damaged, unclear or inconsistent with the tractor.
Be cautious with generic online serial-number charts. A chart may refer to a different John Deere 110 machine, a later lawn tractor or an industrial construction model rather than the classic garden tractor.
Using Your John Deere 110 Serial Number to Order the Right Parts
The model decal alone is not always enough to order the correct part. John Deere 110 production ran for more than a decade, and early and late machines can differ in details that matter when sourcing restoration, repair and service components.
Always start a parts enquiry with the complete tractor serial number. For engine work, include the engine model and engine serial number as well.
Understanding serial breaks
A serial break is a point in production where John Deere changed a component, system, design or supplier. Parts catalogues often use serial-break wording to show where one part applies and another takes over.
Common terms include:
-
Serial number below: The part applies before the stated serial number.
-
Serial number and above: The part applies from the stated serial number onward.
-
Before serial number: The earlier production version.
-
After serial number: The later production version.
-
Early production: A component used on earlier tractors.
-
Late production: A component used on later tractors.
-
With or without option: A part that depends on optional equipment or a particular tractor configuration.
Known serial breaks on the John Deere 110
The John Deere 110 remained in production long enough for differences to exist between early and late tractors. Read every serial-range note in the applicable official parts catalogue before ordering.
Do not assume that a part listed for a 1963 110 will fit a 1974 110, or that a part from a later John Deere lawn tractor will fit either version. Steering, sheet metal, electrical equipment, mower-drive components, engine-related parts and attachment hardware should be matched to the exact tractor serial range and visible component design.
Ordering parts correctly
-
Photograph and record the complete tractor serial number.
-
Confirm that the machine is the original 1963–1974 John Deere 110 garden tractor.
-
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 part with the parts diagram before placing an order.
-
Check mounting points, shaft diameters, belt routing and electrical connections where relevant.
-
Ask a John Deere dealer or knowledgeable supplier to confirm uncertain parts before ordering.
Aftermarket catalogues sometimes group several John Deere 110 production versions under one listing. Treat a broad “fits John Deere 110” claim as a starting point, not a guarantee.
Maintenance and Service Differences by Serial Range
Basic service work on a John Deere 110 may appear straightforward, but the correct maintenance information depends on the tractor’s production version and the engine actually fitted.
A restored or working tractor may have received replacement parts over several decades. It may therefore combine original components with later repair parts, reproduction components or equipment from another machine.
Use service information that matches:
-
The tractor serial-number range
-
The engine model and engine serial number
-
The installed mower deck or attachment
-
The actual steering, electrical and drive-system configuration
-
Any documented conversion or restoration work
Do not order filters, belts, ignition parts, batteries, fluids or electrical components solely by searching “John Deere 110.” Confirm the production range and the installed component first.
Maintenance records worth keeping
Keep a written or digital record of:
-
Tractor serial number
-
Engine model and serial number
-
Mower-deck or attachment identification number
-
Dates of oil and lubrication service
-
Belt and blade replacement details
-
Electrical repairs
-
Engine rebuild or replacement history
-
Photographs of the tractor before major restoration work
This record can save time during future repairs and can improve buyer confidence if the tractor is sold.
Attachment Compatibility for the John Deere 110 by Serial Number
Attachment compatibility depends on more than the John Deere 110 model name. The original garden tractor was produced across several body and equipment changes, and attachment fitment may depend on the production range, mounting hardware, drive arrangement and the specific attachment itself.
Before buying a used mower deck, snow attachment, blade, tiller or other implement, compare:
-
Tractor serial number
-
Attachment identification number
-
Mounting points and brackets
-
Belt routing or drive arrangement
-
Lift linkage configuration
-
PTO or pulley arrangement
-
Tyre clearance
-
Required brackets, guards and hardware
-
Condition of attachment hangers, lift arms and drive components
Verifying compatible attachments
Never assume that an attachment fits simply because it is painted John Deere green or came from another “110.” Confirm both the tractor serial number and the attachment identification number before spending money on used equipment.
Checking Recalls and Safety Notices Using Your John Deere 110 Serial Number
A safety campaign, recall action or service notice can apply only to a particular machine range, component or configuration. The original John Deere 110 garden tractor is now a historic machine, and its current condition may depend more on decades of repairs and modifications than on its original factory specification.
Use the tractor serial number when asking a John Deere dealer about any available safety information. Keep the number with your service and ownership records.
-
Record the complete tractor serial number.
-
Photograph the plate clearly for your own records.
-
Contact a John Deere dealer and request a check for applicable safety information.
-
Inspect the machine for condition issues that matter on older garden tractors, including brakes, steering, fuel lines, belts, guards, tyres and electrical wiring.
-
Address damaged safety guards, leaking fuel components and poor steering or braking before operation.
Using the John Deere 110 Serial Number When Buying or Selling
Checks for buyers
The serial number is one of the most useful tools when evaluating a John Deere 110 offered for sale. It helps you establish whether the seller’s description is broadly consistent with the tractor and whether the machine is an early or late production example.
Before buying, check:
-
That the serial-number plate is present below the steering column
-
That the number matches available paperwork
-
Whether the tractor is the original 1963–1974 garden tractor rather than another John Deere 110 model
-
Whether the serial number supports the advertised production year
-
Whether the engine number is being confused with the tractor serial number
-
Whether mower-deck or attachment numbers are being presented as tractor identification
-
Signs of plate removal, altered characters, unusual rivets, mismatched paint or recent work around the plate
-
Whether the installed engine and attachments appear consistent with the seller’s description
-
The condition of steering, brakes, fuel system, tyres, electrical wiring and safety guards
Pause the purchase if there is a serious identity discrepancy, missing identification information or paperwork that does not make sense.
Advice for sellers
A clear description can make a John Deere 110 easier to sell and reassure serious buyers. State the tractor serial-number year range, but avoid publishing a high-resolution image of the complete serial-number plate in a public advert.
A useful advert should include:
-
The verified model designation
-
The estimated production year based on the serial number
-
Hours, if known and credible
-
Engine information
-
Included mower deck or attachments
-
Known repairs and replacement components
-
Service history
-
Clear photographs of the tractor’s condition
-
A statement that the full serial number can be provided privately to a serious buyer, dealer, insurer or parts supplier where appropriate
What If You Cannot Find or Read the Serial Number?
Plate is dirty, painted over or faded
Use strong lighting, gentle brushing and a clean cloth. Photograph the plate at several angles and record every character you can read. Avoid aggressive cleaning methods that could destroy remaining identification details.
Plate is corroded or damaged
Record all visible characters, including uncertain ones. Check old service invoices, ownership documents, restoration photographs and dealer records. A John Deere dealer may be able to help interpret partial information when supported by the correct machine details.
Plate is missing
Check for legitimate documentation, historic service records, prior ownership records and identification information on installed attachments or components. These can help describe the machine, but they do not replace the missing tractor serial-number plate.
Do not manufacture, restamp, alter or create a replacement identification plate. Contact a John Deere dealer and, where ownership, theft or registration matters, the appropriate local authority.
PIN does not match paperwork
A mismatch may result from:
-
A data-entry error
-
Incorrect or mixed paperwork
-
An engine or attachment number being mistaken for the tractor number
-
Replacement components or a replacement engine
-
A previous owner recording the wrong number
-
A more serious ownership or identity issue
Resolve the discrepancy before buying, selling, insuring or registering the machine.
John Deere 110 Serial Number FAQ
Where is the serial number on a John Deere 110?
On the original 1963–1974 John Deere 110 garden tractor, the serial-number plate is located below the steering column. Clean the area carefully, use good lighting and record every digit exactly as shown. Do not confuse the tractor serial number with the engine number, mower-deck number or a casting number found on another component.
What does the serial number on my John Deere 110 identify?
The serial number identifies the individual original John Deere 110 garden tractor and places it within the production sequence. It can be used to estimate the production year, select the correct parts-catalogue range and help distinguish early from late production machines. It does not prove that every component on the tractor is original.
Is the John Deere 110 serial number the same as a VIN?
Not in the modern automotive sense. The original John Deere 110 garden tractor predates the 17-character VIN format commonly associated with road vehicles and later equipment. Its tractor serial number is the key identification number for parts, historical identification and ownership records.
Is the Product Identification Number the same as the serial number?
Owners often use PIN and serial number interchangeably, but the original John Deere 110 garden tractor uses a traditional serial-number identification system rather than the later 17-character PIN format used on many newer John Deere machines. For this tractor, the number on the identification plate below the steering column is the important machine identifier.
Can I find the year of my John Deere 110 from the serial number?
Yes, if it is the original 1963–1974 John Deere 110 garden tractor and the serial number is readable. Compare the number with the correct 110 year chart in this guide. Use the result alongside body style, decals, equipment and historical paperwork, especially if the machine has been restored or modified.
Are official serial-number year charts available for the John Deere 110?
Serial-number production ranges are widely used to identify the year of the original 1963–1974 John Deere 110 garden tractor. For a final confirmation, especially on a machine with unusual equipment or uncertain history, provide the complete serial number to a John Deere dealer or a specialist familiar with original Deere garden tractors.
How accurate are online John Deere 110 serial-number year charts?
A chart can be useful only when it clearly applies to the original 1963–1974 John Deere 110 garden tractor. The model number 110 has been used on other John Deere products, so a generic “John Deere 110” chart may refer to a different machine. Compare the serial number, tractor type and visible configuration before relying on any chart.
What is the difference between the tractor serial number and engine serial number?
The tractor serial number identifies the John Deere 110 garden tractor itself. The engine serial number identifies the engine fitted to it. You normally need the tractor serial number for chassis, steering, mower-drive and attachment parts, while engine repairs may require the engine model and engine serial number.
Where is the engine serial number on a John Deere 110?
The engine identification is located on the engine itself, but the exact position can vary with the engine version and whether the tractor retains its original engine. Look for an engine-mounted identification label or stamped area. Confirm the engine model and number through the correct engine documentation before ordering engine-specific parts.
Do I need the engine number or tractor serial number to order parts?
Use the tractor serial number for parts related to the John Deere 110 chassis, steering, transmission, electrical system, mower mounting and attachments. Use the engine model and engine serial number for engine-specific components. For some jobs, such as belt, pulley or charging-system repairs, you may need both numbers.
Why does the parts catalogue ask for a serial-number range?
The catalogue uses serial ranges because John Deere may have changed a component during production. A part marked “serial number below” applies to an earlier machine, while “serial number and above” applies to a later version. The range helps prevent ordering a part that looks similar but does not fit your tractor.
What is a serial break on a John Deere 110?
A serial break marks a point at which John Deere changed a part, design, supplier or assembly. It may affect replacement parts even when two tractors are both labelled John Deere 110. Read serial-range notes carefully and compare the old component with the relevant parts diagram before ordering.
Which John Deere 110 parts are most likely to change by serial range?
Items that can require careful serial-range checking include steering components, sheet metal, electrical parts, mower-drive equipment, lift linkage, belts, attachment mounting hardware and engine-related components. The exact parts affected depend on the production range and configuration, so confirm the tractor serial number before ordering.
Does maintenance differ by serial number on a John Deere 110?
Basic service principles remain similar, but the correct parts, service procedure and installed equipment can differ between early and late tractors. Engine replacement history can also change filter, ignition, fuel-system and belt requirements. Use maintenance information that matches the tractor serial range and the actual engine fitted.
Can filters change by serial number or engine version?
Yes. Engine-related service parts can depend on the engine model and serial number, especially if the tractor has received a replacement engine over its lifetime. Never order engine filters or ignition components solely from the John Deere 110 model decal. Confirm the engine identification first.
How do I use a John Deere parts catalogue with my 110 serial number?
Start by confirming that the machine is the original 1963–1974 John Deere 110 garden tractor. Enter the model into the correct parts catalogue, then use the tractor serial number to follow any early-production, late-production or serial-break notes. Compare the illustration, reference number and old component before ordering.
Can a John Deere dealer identify build details from the serial number?
A John Deere dealer may be able to help identify the production range and applicable parts information from the complete tractor serial number. The level of historical detail available can vary. Take a clear photograph of the identification plate and provide the dealer with the full number rather than a partial sequence.
Can I check recalls or safety notices using my John Deere 110 serial number?
Yes. Record the complete tractor serial number and ask a John Deere dealer to check for applicable safety information. Because these tractors are historic machines, also inspect their present condition carefully. Fuel-system deterioration, damaged wiring, worn steering, poor brakes and missing guards can create safety issues regardless of original factory information.
Is it safe to share a John Deere 110 serial number online?
Avoid publishing a clear, high-resolution photograph showing the complete serial number in a public advert or social-media post. A serious buyer, dealer, insurer or parts supplier may need the full number, but it is generally better to share it privately when there is a legitimate reason.
What should I do if the serial plate is missing?
Check historical documents, dealer service records and previous restoration records, but do not create or restamp a replacement plate. A component number or engine serial number may help describe the machine, but it does not replace the tractor identification. Contact a John Deere dealer and the appropriate authority if ownership or legal identity is in doubt.
How can I tell whether a John Deere 110 serial plate has been tampered with?
Look for unusual rivets, fresh paint surrounding only the plate, inconsistent ageing, damaged mounting areas, uneven characters or evidence that the plate has been removed and reattached. None of these signs proves wrongdoing by itself, but they justify further checks. Compare the number with paperwork and consult a dealer before completing a purchase.
Can I legally replace a damaged identification plate?
Do not assume that replacing an identification plate is permitted. Rules can depend on the country, ownership status and reason for replacement. Do not make, stamp or alter a plate yourself. Ask a John Deere dealer and, where relevant, the appropriate authority for guidance before taking any action.
Why does the serial number not match my paperwork?
The mismatch may be a simple clerical error, an engine number recorded as the tractor number, mixed paperwork from another machine or a more serious identity issue. Check each number against the physical tractor, engine and attachments. Resolve the issue before purchasing, selling, insuring or registering the machine.
Do attachments for a John Deere 110 depend on serial number?
They can. The original John Deere 110 had a long production run, and attachment fitment may depend on production range, mounting hardware, lift linkage, drive arrangement and the specific attachment. Verify the tractor serial number and attachment identification before buying a mower deck, snow attachment, blade, tiller or other used equipment.
Which mower decks, snowblowers or blades fit a John Deere 110?
Fitment should be confirmed through the official John Deere parts catalogue and the identification information for both the tractor and attachment. Do not rely on appearance, paint colour or a seller’s statement that an attachment “came off a 110.” Mounting hardware, drive components and lift systems must match the exact tractor configuration.
Will an attachment from another John Deere model fit my tractor?
Not necessarily. Even if another attachment looks similar, it may have different mounting brackets, lift hardware, pulleys, belts, guards or drive arrangements. Confirm compatibility using the tractor serial number, attachment identification number and official parts information before purchase.
Can I decode every character in my John Deere 110 serial number?
No. The original garden tractor’s number is mainly used as a serial sequence and production-year reference. Do not apply later John Deere PIN-decoding charts to this older tractor. Use the serial number to establish the correct production range, then confirm details through appropriate parts and service information.
Does the serial number show where my John Deere 110 was built?
The serial number can help identify the tractor within its production sequence, but it should not be used alone to make unsupported claims about factory, build date or original dealer. For historical documentation, consult a John Deere dealer or specialist resource using the full serial number and verified machine details.
How should I record and store my John Deere 110 serial number?
Photograph the identification plate clearly, write the number exactly as shown and keep the record with service receipts, insurance documents and ownership paperwork. Also record the engine model and serial number, plus identification details for mower decks and attachments. Keep one copy securely offline and another in your maintenance records.
Can I still get parts for an early John Deere 110?
Parts availability varies by component. Some original parts may remain available through dealer channels, specialist suppliers, used-parts sellers or restoration businesses, while others may require repair or careful sourcing. The tractor serial number is essential because an early production part may not match a later 110.
How can I identify my machine if the John Deere 110 decals are missing?
Start with the serial-number plate below the steering column. Confirm the tractor’s overall configuration, bodywork, steering layout, engine identification and attachment mounting arrangement. Missing decals alone do not prevent identification, but do not rely on paint or replacement decals as proof that a machine is an original 1963–1974 John Deere 110.
Does the serial number affect resale value?
Yes, indirectly. A readable, credible serial-number plate helps establish the tractor’s production year and supports a buyer’s confidence in the machine’s identity. Originality, condition, restoration quality, included attachments, mechanical health and documented service history usually have a greater effect on value than the serial number alone.
Are there known serial-number-related service bulletins for the John Deere 110?
Service information can depend on production range, installed engine and attachment configuration. Ask a John Deere dealer or a specialist familiar with original John Deere garden tractors to check the complete serial number against the applicable information. Avoid relying on a bulletin or repair instruction intended for another John Deere 110 generation.
Who should I contact if I am still unsure about my John Deere 110 serial number?
Start with a John Deere dealer and provide a clear photograph of the identification plate, the complete serial number, engine identification and photographs of the tractor. For restoration and historical questions, a reputable John Deere garden-tractor specialist can also help compare the machine with the correct production range.
