This ensures that corn kernels are cracked to aid digestibility. A two-piece grater floor is easily fitted into the flywheel housing concave. Adjustable breaker plates and additional masher bars attach to the flywheel itself. Drive is taken direct from the tractor PTO via a universal shaft fitted with an overrun clutch.
Interchangeable gears enable the flywheel speed to be set for either grass or corn.
A choice o three chop lengths is achieved by controlling the feed roller speed - this is varied by location the drive belt in one of three drive pulley grooves. Removing alternate knives doubles the chop length options. Four rollers compress the crop and present it evenly to the flywheel knives. Drive is via a chain from the flywheel to the feed roller gearbox. From the gearbox, slip clutch protected shafts drive the feed rollers.
