What It Is

This is a direct-replacement deluxe yellow seat for select John Deere lawn tractors, designed to restore comfort and visibility on mid-to-late model 300 and 500 series machines. It’s a drop-in upgrade for worn or damaged OEM seats, especially on garden tractors used for mowing, towing, or light-duty work.

Fitment & Compatibility

Before buying, verify your tractor’s model and serial number. This seat fits:

• John Deere X500 (s/n 020001>), X520 (s/n 020001>), X530 – garden tractors with high-back seat mounts.
• X300, X304, X305R, X310, X320, X324, X330, X340, X350, X350R, X360 – all with serial numbers above 020001 (check your machine’s ID tag).
• Also fits X300R and select older 300-series models (e.g., L120, L130, LA145, LA165, LA175 – verify mount pattern).

What to measure/check:

• Seat mounting hole spacing: 7.5" x 7.5" (center-to-center) – standard for most Deere 300/500 tractors.
• Seat pan width: ~18" – ensure clearance with your fender deck.
• Slide rail length: ~10" – fits standard Deere slide brackets.
• Not compatible with X300 models below s/n 020001 (pre-2009) or X500 series below s/n 020001 – those use a different seat pan.

OEM vs aftermarket: This is an aftermarket replacement for John Deere part AM136044. It matches OEM dimensions, foam density, and mounting hardware. Some users report slightly softer foam than OEM – acceptable for most.

Key Things to Know

• Installation difficulty: Easy – 15–30 minutes with basic hand tools (10mm socket, screwdriver). Unbolt old seat, transfer slide bracket if needed, bolt new seat to tractor frame.
• Hardware included: Yes – comes with mounting bolts, washers, and nuts. No need to buy extra.
• Common gotcha: The seat slide lever may need minor adjustment if your tractor has a tilt-up seat. Loosen the lever set screw with a 3mm Allen key and reposition.
• Durability: Yellow vinyl holds up well under sun exposure but may fade slightly over 2–3 years if stored outside uncovered. Use a seat cover or garage storage for longer life.

Should You Buy It

If you own a compatible John Deere X300 or X500 series (s/n >020001) with a worn or cracked original seat, this is a solid, budget-friendly replacement that restores comfort and matches factory color. It’s not for older Deeres (pre-2009) or non-Deere brands – skip it if your mount pattern differs. For the price, it’s a reliable choice for DIY owners who want a durable, comfortable seat without paying OEM markup.
