Identify the John Deere X354 by its tractor PIN, installed engine and mower-deck record before selecting parts or comparing a used machine. Keep replacement-engine history and attachment identities with those records. A model badge or photograph cannot establish the equipment now fitted.
Identify the fitted X354 configuration
Deere’s 22 December 2020 price book describes X354 base 5194M for the United States and Canada with a 21.5-hp FR651V engine, K46 hydrostatic transmission, manual four-wheel steering, a 42-inch Accel Deep deck and foot-pedal lift. Treat this as that dated configuration, not a specification for every year, market or replacement component.
The provides a configuration reference; its URL alone cannot identify a used machine. Record the full PIN and engine model and serial, then confirm the deck and steering equipment actually present.
Inspect the actual guards, mounts, controls, seat and attachment connections for damage or missing components. Record concerns for a qualified inspection; appearance does not establish internal condition.
Measure gates, storage openings and access with the actual deck and attachments included. Check operator fit and the controls you will use, following the matched manual’s operating restrictions.
Read the dated X354 engine-service references
Deere’s November 2019 table lists LG265 for X354 serial 010001 onward without naming an engine. The September 2023 guide labels LG265 for Canada/USA and AUC17070 outside Canada/USA. Confirm the installed engine, market and current kit application before ordering. Establish a replacement engine’s identity first; the old model row does not identify it.
- Oil filter: AM125424.
- Air filters: MIU12554 primary and MIU12555 secondary.
- Fuel filter: AM116304; spark plug: M805853.
These are September 2023 reference numbers, not a current itemized kit inventory. Ask the seller to confirm contents and the planned service task before ordering separate filters as well as a kit. The AM116304 offer contains two filters; a pack count is not the number required per service.

X354 kit and fuel-filter choices after engine identification
Start with the dated serial and regional references, then confirm the fitted engine, market, current kit application and itemized contents. Separate filters can duplicate a kit; choose them for an identified service task.
John Deere LG265 maintenance kit
Deere’s November 2019 X354 row lists LG265 from serial 010001 without an engine code. September 2023 labels it for Canada/USA, with AUC17070 outside that region. Confirm the installed engine and current application; no outside-region substitute is offered.
AM116304 fuel filter
The September 2023 X354 guide names AM116304. Confirm current application to the actual engine and follow its fuel-service precautions. This listing contains two filters; compare kit contents and the planned task before adding separate filters.

Match the X354 deck type and cutting arrangement
The September 2023 X354 guide has three separate deck pages. Read the actual deck model and serial and identify its cutting equipment. A 42-inch Mulch deck is not established by fitting a mulch accessory to any 42-inch Accel Deep deck.
- 42-inch Accel Deep: UC22008 mower blade, GX25668 bagging blade, M174994 deck belt and GX10168 wheel.
- 42-inch Mulch: AM140973 high-lift or AM140332 low-lift blades, M169485 and M174313 V-belts, and M111489 wheel. This page does not label those belts primary and secondary.
- 48-inch Accel Deep: UC22009 mower blade, M169485 primary belt, M169500 secondary belt, M111489 wheel and M113955 roller.
Sharing M169485 in two entries does not make the other belt or assembly interchangeable. UC35484 is listed as the tractor traction belt, a different function from these deck belts. Obtain current assembly-specific confirmation before purchase. No deck or traction-belt offer is supplied here.
AM130907 is the leveling gauge on all three deck pages. Use the matched manual for preparation, tire-pressure checks, measuring points and adjustments. A gauge does not identify the deck or prove the cause of every uneven-cutting complaint. The UC22009 offer is a three-blade package conditional on the documented 48-inch deck; it is not a 42-inch blade choice or complete mulch equipment.

X354 blade and gauge choices after deck identification
Keep 42-inch Accel Deep, 42-inch Mulch and 48-inch Accel Deep references separate. The blade offer here is conditional on the documented 48-inch deck; no 42-inch blade or complete mulch-kit offer is supplied.
Accel Deep: UC22009 mower blades
UC22009 is the September 2023 X354 48-inch Accel Deep mower-blade reference. Confirm the actual deck and current number before selecting this three-blade package. It is not either 42-inch deck choice or a complete mulch installation.
John Deere AM130907 deck-level gauge
All three September 2023 X354 deck pages show AM130907. Use the matched manual for preparation, tire-pressure checks, measuring points and adjustment. The gauge does not identify the deck or establish the cause of every cutting fault.

Prepare X354 inspection and service with the matched manuals
Use the applicable tractor, engine, deck and attachment manuals for safe access, service intervals, fluids, filters, torque and storage. Follow their shutdown, cooling, isolation and support instructions before approaching service points. Do not run a blade or reach beneath unsupported equipment for a photograph.
Check the actual control functions and equipment condition in a permitted demonstration. Stop and obtain an inspection if a fault prevents a safe check; an advertised feature is not evidence that the fitted mechanism operates correctly.
Assess the actual X354 and complete offer
Request operating hours, dated service and repair records, replacement-engine details and explanations of present faults. Match the documents to the machine being offered and ask for an explanation of any gaps.
Photograph or transcribe safely accessible markings, guards, mounts and visible concerns after the required shutdown and isolation. A mirror or light helps collect records; it cannot verify internal condition, diagnose a fault or establish part compatibility.
Compare the complete cost of the actual machine and alternatives: included deck and attachments, immediate repairs, transport, finance terms and warranty. Compare models with matched equipment, workload and condition; calculate costs from the actual offer and expected work.
Equipment & supplies
Aids for recording the actual X354 equipment
Use these optional aids only where the matched manuals permit safe access after shutdown, cooling and isolation. Keep readable identities and visible concerns for an enquiry or inspection; neither aid establishes current fit or internal condition.
Ullman HTC-2 inspection mirror
The Ullman HTC-2 mirror can help read safely accessible X354 engine, deck or attachment markings. Keep a clear transcription or photograph and resolve uncertain characters before a parts enquiry. A mirror provides no compatibility or internal-condition verdict.
Streamlight MicroStream pocket light
The Streamlight 66318 MicroStream uses an AAA battery; it is not the USB version. Illuminate permitted, safely accessible X354 labels, guards or mounts for records. A lit record cannot diagnose a fault or establish replacement-part fit.
