The partial tilt arrangement consists of the following components: tilt cylinder (1) and mounting arrangement (2). The partial tilt felling head can rotate 20 degrees in either direction.
The mounting arrangement is bolted to the swing bearing that is mounted on the felling head. The tilt cylinder is mounted to mounting arrangement (2) and the frame of the felling head with pins. The tilt cylinder controls the tilt movement of the felling head.

The full tilt consists of the following components: mounting arrangement (3), balancer frame (4), Swing Bearing (5), two tilt cylinders (6) and cushion valve (7). The full tilt felling head can rotate 110 degrees in either direction.
The swing bearing is made up of the following components: a mounting plate, a gear, a side tilt bearing and a thrust washer. The swing bearing bolts to the felling head.
The balancer frame consists of gear segments and a frame. The gear segments are bolted to the frame. The balancer frame has an oil tank that is built into the frame. The balancer frame is mounted to mounting arrangement (3) with a pin. The pin is held in place with a tapered bushing. The bushing bolts to mounting arrangement (3) .
The mounting arrangement bolts to swing bearing (5). The gear segments on balancer frame (4) are meshed with the gear in swing bearing (5). The oil from the tank of balancer frame (4) lubricates the gear segments and the gear. Gravity controls the flow of the oil from the tank to the gears.
Cushion valve (7) is mounted on the frame of mounting arrangement (3). Cushion valve (7) contains two crossover relief valves. The crossover relief valves protect the full tilt circuit from sudden pressure rises in tilt cylinders (6). The valves also assist in preventing cavitation of the circuit during operation.
Tilt cylinders (6) are mounted to mounting arrangement (3) with pins. The tilt cylinders (6) control the tilt movement of the felling head.
