Anti-scalping roller conversion kits for GM10E, GM11, and GM20 Series Grooming Mowers
Anti-scalping roller attaches to front of deck

An anti-scalping roller kit can be ordered as an attachment for field conversion for FM and GM Series Grooming Mowers when it is not standard equipment. The roller is attached to the front of the cutting deck to help reduce scalping.
Each kit contains one roller.
Mulching kits for grooming mowers
Kit includes baffles, blades, and guard supports

A mulching kit is available as an attachment for field conversion. The mulching kit includes unique mulching blades, baffles, and guard supports to produce smaller clippings, which decompose faster than clippings that haven’t been mulched.
Operators should follow the one-third rule for cutting height when mulching in grass.
This mulching kit also does an excellent job when mulching leaves.
Safety chain shield
Standard chain shield for added safety
GM20 Series Grooming Mowers come standard with a safety chain shield.
