KUAFU Tractor Seat Compatible with John Deere X300 X300R X304 X310 X320 X324 X340 X360 X500 X520 X530 Replacement for AM136044 Riding Lawn Mower Seat Yellow+Black

What It Is

This is a direct-replacement aftermarket tractor seat for John Deere X300 and X500 series lawn tractors, designed to replace OEM part AM136044. It fits riders with a standard 4-bolt seat mount pattern and provides a basic mid-back seat in yellow and black.

Fitment & Compatibility

Before buying, verify your mower’s model number (e.g., X300, X310, X500) and that the seat mount uses a 4-bolt pattern with roughly 8.5” x 8.5” bolt spacing. This seat does not fit zero-turn mowers or older Deere models with a 2-bolt or slide-rail system. Measure your existing seat’s mounting holes center-to-center—if they match 8.5” square, this will bolt on. Also check that your mower has enough clearance for the seat’s thickness (approx. 6” at the cushion). This is an aftermarket part, not OEM John Deere, so the foam and vinyl may be slightly firmer and less contoured than the original.

Key Things to Know

• Installation is straightforward – Remove 4 bolts, swap seat, tighten. No wiring or modifications needed.
• Foam density – Users report it’s firmer than OEM, which can be more supportive for larger riders but less plush for long mowing sessions.
• Color match – The yellow is close but not an exact match to older John Deere yellow; it’s slightly brighter. Black vinyl is standard.
• Armrests not included – This seat has no armrests; if your current seat has them, you’ll need to buy a different model or add aftermarket armrests separately.

Should You Buy It

If you need a budget-friendly, functional replacement for a worn-out John Deere X300 or X500 series seat and don’t mind a firmer ride and slightly off-color yellow, this is a solid value. It’s not for perfectionists wanting exact OEM look or plush comfort, but for the price it’s a reliable, easy swap that gets you back mowing.
