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. Simple knife replacement Variable knife adjustment allows replacements to be fitted easily, with no excessive grinding needed. Sharpening takes only a few minutes - achieved by simply reversing the direction of the flywheel and winding in the grinding disc. Instant feed reverse The P ttinger system for reversing the feed rollers is quick and reliable. This steel faced pulley then meshes with a rubber faced friction pulley - smoothly and quickly reversing the feed rollers.
