Hydraulic Wing Deck Locks

Deck Baffling for Quality Cut
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
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.
