What It Is

This is a 6-pack of mulching blades (20.87" long) designed for 60" mower decks, specifically for John Deere commercial and residential zero-turn and compact utility tractors. They replace OEM part numbers TCU15881, M128485, M131958, M144196, M163983, and M133381.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 60" cutting width and uses blades that are 20.87" long with a 1" center hole and 0.25" thick. These fit John Deere models 737, 757, 777, 797, 997, 1023E, 1025R, and Z930A, plus many others with 60" decks. Check your current blade’s part number or measure length from tip to tip. These are aftermarket replacements for OEM blades—verify your spindle pattern matches (most 60" Deere decks use three blades, but double-check your specific model).

Key Things to Know

• Quality: G6 Gator blades are known for durable steel and aggressive mulching design. Expect good lift and fine clipping shredding, but they may wear slightly faster than OEM on heavy commercial use.
• Installation: Straightforward swap—remove the center bolt, replace blade, torque to 70-90 ft-lbs. Use a blade stop or block to prevent spinning. No special tools beyond a socket wrench.
• Gotchas: These are mulching blades, not lift or bagging blades. If you frequently bag or side-discharge, consider a hybrid or dedicated blade. Also, the 6-pack covers three blades per deck with two spares—make sure you need six total (some 60" decks use three, not six).
• Balance: New blades come balanced, but always check with a balancer before installing to avoid vibration.

Should You Buy It

Buy this if you own a compatible John Deere with a 60" deck and want a cost-effective mulching upgrade over OEM—especially for residential or light commercial mowing where fine clipping breakdown matters. Skip if you primarily bag or need lift blades for uneven terrain.
