The John Deere X394 48-inch listing describes a 23-hp FR691V engine, K58 hydrostatic transaxle and power four-wheel steering. Those specifications belong to the described configuration. Identify the tractor PIN, fitted engine and actual mower deck before using a specification to select parts.
See the for that setup. Deere’s May 2023 replacement-parts guide also contains a separate 54-inch Accel Deep page; the 48-inch listing does not establish that every X394 has that deck.
Confirm the X394 machine before servicing it
Record the full tractor PIN, engine model and serial, deck model and serial, market and replacement history. Find publications covering those identities and serial ranges. A replacement engine needs its own parts enquiry. Keep tractor, engine, transmission, deck and attachment records separate where their application notes differ.
Read the dated X394 engine-service references
Deere’s November 2019 cross-reference lists LG265 for X394 serial 010001 onward without an engine code. The May 2023 guide also lists LG265, without a kit market condition in that entry. Regional battery labels on the same page do not define kit scope. Confirm the fitted engine, market and current kit specification before ordering.
- Engine oil filter: AM125424.
- Air-filter references: MIU12554 primary and MIU12555 secondary.
- Fuel filter: AM116304; spark plug: M805853.
These May 2023 references do not prove today’s LG265 contents or a universal service interval. Match the seller’s itemized contents to the work planned before adding separate filters. The selected AM116304 package contains two filters, not evidence that one service needs two.
Equipment & supplies
X394 kit and fuel-filter choices after engine identification
Start with the dated X394 references, then confirm the fitted engine, market, current application and itemized package contents. Separate filters may duplicate a kit; select them only for an identified service task.
John Deere LG265 maintenance kit
Deere’s November 2019 X394 row lists LG265 from serial 010001 without an engine code; its May 2023 guide also lists the kit. Confirm the actual engine, market and current contents. Regional battery labels do not establish kit scope.
AM116304 fuel filter
The May 2023 X394 guide names AM116304 fuel filter. Confirm current application to the fitted engine and follow the applicable fuel-service precautions. This listing contains two filters; compare kit contents and the work planned before adding it.

Keep X394 transmission work separate
The May 2023 guide lists MIU800986 transmission filter, TY22035 low-viscosity Hy-Gard oil and M126012 drive belt. AM125424 is the engine oil-filter reference, and the mower-deck belts have their own numbers. No transmission filter, fluid or drive-belt offer is supplied here.
Transmission quantities differ between sources: the undated 48-inch reminder prints 2.17 L (2.28 qt), while the May 2023 guide prints 2.8 L (3 qt). Obtain the actual transmission identity and applicable current procedure before service. These historical entries are not a refill instruction, and this page does not resolve the difference by assumption.
Match the X394 deck and cutting arrangement
- The May 2023 48-inch Accel Deep page lists UC22009 standard blade, M127673 mulch blade, M169485 primary belt and M169500 secondary belt.
- The 54-inch page lists UC22010 standard blade, M152726 high-lift blade, M169485 primary belt and M169486 secondary belt.
- Both pages list AM130907 deck-leveling gauge, M111489 gage wheel and M113955 roller.
The undated 48-inch reminder instead names M145476 side-discharge blade. It agrees on M127673 mulch blade and the two belt roles, and lists BM24993 MulchControl kit. These entries do not establish a current supersession or prove a blade set completes a mulch installation. Confirm the actual deck, cutting configuration and required hardware.
The three-blade UC22009 offer below is conditional on the documented 48-inch reference; it is not the 54-inch choice. A common primary-belt number does not make the different secondary belts interchangeable. Confirm each current deck reference before purchase.
Equipment & supplies
X394 blade and leveling choices after deck identification
The May 2023 X394 guide separates 48-inch and 54-inch Accel Deep references. Confirm the actual deck and current application. The blade listing here is conditional on the documented 48-inch reference; no 54-inch blade or complete mulch-kit offer is supplied.
Accel Deep: UC22009 mower blades
The May 2023 X394 48-inch Accel Deep page names UC22009. Confirm the current deck reference before buying this three-blade listing. The undated reminder instead names M145476 for side discharge. This is not the 54-inch choice or a complete mulch installation.
John Deere AM130907 deck-level gauge
Both May 2023 X394 deck pages name AM130907. Use the matched manual for preparation, measuring points and adjustment, including its tire-pressure checks. The gauge does not identify the fitted blade or diagnose every uneven-cutting fault.

Prepare safe X394 inspection and servicing
Use the fitted engine and tractor/deck manuals for intervals, fluids, procedures, torque, disposal and operating restrictions. Follow shutdown, cooling, isolation, support and blade-handling precautions before label access or deck work; never reach into an operating deck. Check tire condition and specified pressures before taking deck-level readings, then use the matched measurement and adjustment procedure.
Record the actual seat and controls, tires, guards, mounts, attachments and access/storage dimensions. Compare the intended work and route with manual limits. A mirror or light may help record permitted, safely accessible markings; neither establishes internal condition or replacement-part fit.
Used X394 checks and written offer
Request hours, dated maintenance records and repair invoices. Record leaks, wiring or deck damage, missing guards and unresolved faults, then obtain a qualified repair quotation. If the machine is demonstrated, observe only from the operator’s position as the manual permits. Unusual steering or drive behavior requires qualified inspection before purchase or use.
Have the included attachments and mounting hardware, repairs, delivery, financing, warranty and service support written into the offer. Compare total cost using actual condition and records rather than a generic model price or unsupported testimonial.

Aids for recording the actual X394 equipment
Use these optional aids only where the X394 manuals permit safe access after shutdown, cooling and isolation. Keep readable identities and visible concerns for the service enquiry; a mirror or light cannot establish current fit or internal condition.
Ullman HTC-2 inspection mirror
The Ullman HTC-2 mirror can help read a safely accessible X394 engine, deck or attachment marking. Retain a clear transcription or photograph, resolving uncertain characters before asking for parts. A mirror supplies 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 only permitted, safely accessible X394 labels, guards or mounts for records. A lit record cannot diagnose a fault or establish replacement-part fit.
