GreensPro 1260 machines use a 10.2 cc (0.62 cu in) variable displacement
bidirectional axial hydraulic pump connected to a fixed displacement 2.1 cc (0.13
cu in) hydraulic motor to propel the machine
is driven by the engine through a rubber drive coupling. The hydraulic motor
is directly coupled to the drive roller.
The operator moves the motion control pedals connected to the hydraulic pump
control arm to control the machine direction and speed. With the engine running
and the motion control pedals in the N
supplies no fluid to the hydraulic motor, so that the machine remains stationary.
When one of the motion control pedals is pressed, the traction cable moves the
hydraulic pump control arm, hydraulic fluid flows from the hydraulic pump to the
hydraulic motor and so that the hydraulic motor 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 both 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.
Most of the traction control system components are attached to the bottom of
the chassis. The motion control pedals extend through the chassis, as does the
