8TEN Deck Wheel for John Deere GX345 X350 X570 X380 X590 X580 GX345 GX355 X390 AM125172 AM124706 4 Pack

What It Is

This is a set of four aftermarket deck wheels designed to replace the factory gauge wheels on select John Deere lawn tractors. They support the mower deck, prevent scalping, and reduce wear on the deck shell during turns or on uneven ground.

Fitment & Compatibility

Before buying, confirm your mower model is in this exact list: GX345, X350, X570, X380, X590, X580, GX355, X390. These replace OEM part numbers AM125172 and AM124706. Measure your existing wheel’s outside diameter (should be ~8 inches) and the axle hole diameter (typically 3/4 inch). If your deck uses a different bolt pattern or a smaller wheel, these won’t fit. Also check that your deck has four wheel mounting brackets – some models only have two.

Key Things to Know

• Quality vs OEM: These are aftermarket wheels made from hard plastic. They’re durable for normal residential use but may wear faster than genuine John Deere parts if you mow on rough gravel or asphalt frequently.
• Installation: Simple bolt-on swap – remove a cotter pin or retaining clip, slide off the old wheel, slide on the new one, and reinstall the pin. No tools beyond pliers or a screwdriver are usually needed.
• Common Gotcha: The included bushings may need to be tapped in with a hammer if they’re tight. Also, check that the wheels spin freely after installation – if they bind, the axle may be bent or the bushing not fully seated.
• Pack Size: You get four wheels, but if your deck only uses two, the extras are spares or can be used on another compatible mower.

Should You Buy It

If you own one of the listed John Deere models and need a budget-friendly replacement for worn or missing deck wheels, this 4-pack is a solid value. It’s not as rugged as OEM for heavy commercial use, but for routine lawn care on turf, it performs well and costs significantly less than buying genuine parts individually.
