Hydraulic Wing Deck Locks

Close-up of a flex-wing grooming mower's wing deck hydraulic lift cylinder

The FM4012 has hydraulic lifts for the wing and rear decks to automatically lock them in the up position for transport. It uses a single acting cylinder, requiring only one tractor rear SCV.

Deck Baffling for Quality Cut

Front view of the underside of an FM40 series flex-wing grooming mower, featuring deck baffling around the three blades

Deck baffling around the blade ensures optimum cut quality. The FM4012 deck depth with baffling around the blades ensures exceptional material distribution and a higher quality of cut.

Caster Wheels for Uniform Cut

Green grooming mower shown from the side, featuring caster wheels, a PTO driveline, and a rectangular mower deck

By having four caster wheels per deck, this mower follows ground contours with ease. Tubular caster wheel arms are bolted to rail supports for added durability.
