(1) Rotor tilt cylinder | |
Rotor tilt cylinder (1) tilts the rotor hood. When oil is directed into the rod end of the rotor tilt cylinder, the rotor hood tilts forward. When oil is directed into the head end of the cylinder, the rotor hood tilts toward the rear. When the rod is fully extended, the rotor hood is level.
During normal operation (the rotor hood tilt switch is in the FLOAT position), supply oil from the auxiliary pump is directed into both ends of the rotor tilt cylinder. Since the effective area of the head end of the cylinder is greater than the effective area of the rod end, the cylinder rod extends, and the rotor hood remains level.
The line to the head end of the rotor tilt cylinder contains an orifice and a check valve. the line to the rod end of the cylinder contains an orifice and a check valve. The orifice limits the speed at which the rotor will move.

Cab slide cylinder (2) is located in front of the operator platform. When the cab slide switch is moved to the RIGHT or LEFT position, the cab of the machine moves to the right or left.

Rear door cylinder (3) opens and the cylinder closes rear door (4). Chain (5) can be used in order to hold the rear door open.
Rear Steering Cylinder

The head end of rear steering cylinder (6) is attached to the left rear left bolster, and the rod end of the cylinder is attached to the right rear bolster. A tie rod (not shown) connected to the rear of the bolsters. The steering cylinder and the tie rod steer the rear wheels through pivot assemblies.
Rotor Elevation Cylinder

Rotor depth is controlled by rotor elevation cylinders (9). One cylinder is located on either side of the rotor hood. The head end of the cylinder is pinned to the machine frame, and the rod end is pinned to a chain case. A scale on the front of the cylinder registers the approximate rotor depth.
The rotor lock mechanism is used to hold the rotor at the preset travel height. When the rotor is at the travel height, a spring pin can be removed, and lever (7) can be rotated until the shaft of the lever is positioned between the ears of the bracket which is welded onto the housing of the rotor depth cylinder. This is the TRAVEL LOCK position. Once the lever is in place, the spring pin can be reinstalled in order to hold the lever in this position. When the lever is in the TRAVEL LOCK position, the rotor cannot be lowered.
The machine ECM uses rotor service lock switch (8) to monitor the position of the lever. This switch is a proximity type switch. When the lever is in the unlocked position, the proximity switch senses the presence of the lever. In this case, the machine ECM operates the rotor as normal. When the lever is in the TRAVEL LOCK position, the machine ECM will allow the rotor to be raised but will not allow the rotor to be lowered.
Front Door Cylinder

(10) Front door cylinders | |
Machines which are equipped with the optional hydraulically operated front door contain two front door cylinders (10) .
Hydraulic operation of the front door allows the operator to control the door position in order to match specific operating conditions. In deep, soft soil stabilization applications, the door is often opened completely in order to prevent the plowing of material. In asphalt reclamation applications, the door is usually closed in order to prevent asphalt from being thrown out the front of the mixing chamber. The front door position is also used in order to control the head of material which is in front of the rotor.
