1-2 DESCRIPTION

The Side Mount Rotary Cutter (Fig. 1-1) is an agri- cultural implement designed primarily for cutting brush up to 1 inch (2.5cm) in diameter along ditches

and banks. It is to be used on tractors weighing a minimum of 6000 lbs. (2722 kg) not including ballast and having a minimum of 50 PTO horse- power. Two models are available; the model SM60R, requiring 540 rpm PTO speed and the model SM160R, requiring a 1000 rpm PTO speed. Front and rear discharge shields are standard on each.

The cutter is all hydraulically powered as shown in Fig. 1-2. A hydraulic gear pump is driven by the tractor PTO. The 35 gallons of oil are delivered to the motor at a maximum of 3200 PSI on a cast iron pump and motor. The hydraulic oil is filtered by a suction strainer mounted inside the tank and a canister type return line filter. Each filter is equipped with a bypass to prevent pumpt cavitation, should it become clogged. Slide cylinder and deck pivot cylinders are controlled by the tractor auxiliary hydraulic system.
