GreensPro 1240 machines use a hydraulic transmission driven by the engine
through a rubber drive coupling to propel the machine (
Figure 10 ). The
transmission is connected to the drive roller through a double row chain. The
transmission is a 10.2 cc (0.62 cu in) variable displacement bidirectional axial
hydraulic pump coupled to a fixed displacement 21.8 cc (1.33 cu in) hydraulic
motor.
The operator moves the motion control pedals connected to the hydraulic
transmission control arm to control the machine direction and speed. With
the engine running and the motion control pedals in the N
EUTRAL
position, the
transmission supplies no drive to the traction roller, so that the machine remains
stationary. When one of the motion control pedals is pressed, the motion control
linkage moves the transmission control arm so that the transmission output
turns the drive roller. Machine movement occurs in the direction of the motion
control pedal applied.
The 2 foot-operated motion control pedals are on either side of the steering
wheel column. These pedals control the motion of the traction roller. The pedals
are connected to a common pedal rod pivot so that the motion control pedals
cannot be pressed down at the same time. Pressing the right-hand motion
control pedal will move the machine to the right, and pressing the left-hand
motion control pedal will move the machine to the left. The farther the pedal is
pressed, the faster the machine will move in that direction.
