Caster wheels
By having four height adjustable caster wheels, the GM40 Series Grooming Mower follows ground contours and prevents scalping for even cut quality. Heavy tubular caster wheel arms are bolted to rail supports for long life.

High blade tip speeds allow for better mowing quality at higher operating speeds and precise blade overlap work together to ensure performance and a quality cut.
