The rugged gearbox on the GM20 Series Standard-Duty Grooming Mowers feature highly engineered spiral gears to dramatically reduce noise, increase endurance, and transfer more power to the cutting blades.
Standard chain shield for added safety
GM20 Series Grooming Mowers come standard with a safety chain shield.
Three blades per deck
To meet specific mowing needs, choose from two blade types:
High lift (standard)
The GM10, GM10E, and GM20 Grooming Mowers are only compatible with iMatch using a kit (code 9630).
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.
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.
