Features
High Blade-Tip Speed

High blade-tip speed and precise blade overlap work together to ensure exceptional strength, performance, and a quality cut.
Caster Wheels Follow Ground Contours and Prevent Scalping

By having four caster wheels, the GM40E Series Grooming Mower follows ground contours and prevents scalping. Heavy tubular caster wheel arms are bolted to rail supports for long life.
Floating Hitch for Level Cutting

The floating top link on the GM40E Series keeps the deck tracking over ground contours for a level and smooth cut.
