Travel drive (14) Left track (15) Sprocket (16) Left final driveOil is supplied to left travel motor (2) and by the main pump through the swivel. When the main pump supplies hydraulic oil to the left travel motor, the motor rotates and the motor torque is transferred to final drive (16). The final drive reduces the output speed of the travel motor and the final drive increases the output torque of the travel motor. Final drive (16) transfers the increased torque to left track (14) through sprocket (15).

Control Console (17) Two-speed travel switchThe travel speed can be controlled through fine movements of the travel levers/pedals. The travel speed can also be set to LOW SPEED or HIGH SPEED by using the two-speed travel switch (17). The machine will travel at LOW SPEED until the operator slides the switch to the high speed position. The machine will then move into HIGH SPEED mode. The HIGH SPEED mode is recommended for travel on a flat surface. During gradual downhill travel, the mode may be set to HIGH SPEED for high mobility.

Travel operation (1) Right travel motor (2) Left travel motor (17) Two-speed travel switch (18) Left travel control lever (19) Right travel control lever (20) Idler (21) Forward direction (22) Reverse directionThe direction of machine movement is determined by the direction of the lower structure of the machine. For normal operation, the idlers (20) are toward the front of the machine and travel motors (1) and (2) are toward the rear of the machine. When the machine is arranged for normal travel and control levers (18) and (19) are pushed forward, the machine moves forward. The machine travels backward when the control levers are pulled backward. If the upper structure is turned 180 degrees, the operating directions for the travel levers are reversed.When the machine is in the normal travel position and when one of the travel levers/pedals is moved forward, the respective track travels forward. The machine turns because the stationary track acts as the pivot point. This type of turn is called a pivot turn.The machine will perform a spot turn in order to change the travel direction within a narrow space. To perform a spot turn, move one travel lever/pedal to the rear and move the other travel lever/pedal forward at the same time. The machine
