Strong rear main beater side panels are slanted for clearance and wider spread, and then welded to the strong 5? U-channel side members. The side flares on all H&S heavy-duty manure spreaders are made of 10-gauge g210 culvert grade galvanized steel. The hydraulic endgate features 2 cylinders with hydraulic lines running through a 3? x 3? tube under the floor for protection. The upright position of the hydraulic cylinder stroke allows the gate to lift with the least strain at pivot points. A front splash guard is standard equipment. HEAVY WELDED FRAME The heavy-duty series of H&S manure spreaders feature a massive unitized welded frame with heavy floor supports, side stakes, and wrap-around steel front corners. GEARBOX Gearbox mechanisms and 2-speed drive for the beater and tapered roller apron are bearing equipped. The beater drive gearbox is 1:1.5 bevel gear oil bath equipped with a 4-jaw overrunning clutch for beater shut-off. The apron drive is a 50:1 bronze worm gear with shear bolt protection. UNLOADING SPEED (2-SPEED CHAIN DRIVE) PTO Apron High-Speed/540 RPMs: 8' 8.5? per minute PTO Apron Low-Speed/540 RPMs: 4' 8.5? per minute. EASY CLEAN-UP Sides, front panel and both sides of the rear hydraulic end gate use fiberglass reinforced plywood to provide for easy cleaning and minimal freeze-up. Solid virgin grade poly floor allows for considerably less torque to move a heavy load. The 29? diameter beater has two styles of replaceable beater paddles. Half of the 14 beater paddles are blunt for widespread, and the other half are a sharp ripper-type for cutting and shredding. Beater side wiper blades are also standard equipment. Special cast steel alloy apron idler slides are used instead of idler sprockets, making for years of dependable service. Adjustment for the main apron is easily made by simply loosening the two side bolts and drawing up the long bolt. Greaseable bearings
