(6) Blade Bolt Washers Fits Kubota ZD25F ZD221 ZD323 ZD326 ZG222 ZG227

What It Is

This is a set of six blade bolt washers designed for Kubota ZD and ZG series zero-turn mowers. They secure the blade to the spindle and prevent loosening during operation.

Fitment & Compatibility

Before buying, verify your mower model matches the listed series: ZD25F, ZD221, ZD323, ZD326, ZG222, or ZG227. These are aftermarket washers, not OEM Kubota parts. Check that the center hole diameter matches your blade bolt (typically 5/8" or 3/4" on these models). Measure your existing washer thickness—these should be identical. Also confirm your deck size (48", 54", 60", or 72") is compatible; the washer size is consistent across these decks, but spindle design varies slightly on older models. If you have a ZD331, ZD1211, or ZG222 with a different spindle, these may not fit.

Key Things to Know

• Made from hardened steel to resist deformation under high torque. Cheaper washers can flatten, causing blade wobble.
• Installation is straightforward: replace one washer per blade bolt. Torque to 40-50 ft-lbs (check your manual). Over-tightening can strip the bolt or warp the washer.
• Common gotcha: these washers are not lock washers. They rely on the bolt’s clamping force, so use thread-locker (blue Loctite) on the bolt if your manual recommends it.
• The set includes six washers—enough for three blades (two per blade on most ZD/ZG decks). If your mower has a different blade count, you may need an extra set.

Should You Buy It

If you need a reliable, affordable replacement for worn or missing blade washers on a compatible Kubota ZD or ZG mower, this set is a solid choice. It’s not OEM, but the hardened steel construction matches factory specs for typical residential and light commercial use. Skip it if you require exact OEM parts for warranty or heavy commercial duty.
