PTO - Variable Mode

In this mode, the vehicle can be programmed for stationary or mobile operation.

The variable PTO mode controls engine speed and PTO load engagement is selected by either the PTO in-cab or remote switches. Engine speed selection is variable between base engine idle speed and a maximum of 2100 RPM.

In the mobile PTO mode, the vehicle will operate at a vehicle speed resulting from the current PTO engine speed request and current transmission gear range selected.

Vehicle speed stability is greatly improved by shifting into the transmission manual mode because upshifts are limited. This reduces the maximum vehicle speed while allowing high engine speed operation. Therefore, low vehicle speed operation, 16-40 km/h (10-25 mph) and high PTO engine speed 1500-2000 RPM can be achieved in the manual mode 1 and 2 transmission ranges.

In-cab PTO Switch Operation:

• 1: This is the PTO switch On position. Press and release the 1 switch to engage PTO. PTO will increase the engine speed to the factory preset engine speed. The initial standby speed can be adjusted by holding the accelerator to the desired engine speed, then pressing and releasing the 1 switch. The current engine speed will become the new standby speed. This adjustment can only be done once at the initial engagement of PTO, and the initial standby speed adjustment must be between the engine base idle speed and the maximum PTO engage speed.
• 0: This is the PTO switch Off position. Press and release the 0 switch to disengage PTO. The engine speed will be return to the base idle speed and the PTO load relay will be disengaged.
• SET -: Press and hold the accelerator to obtain the desired engine speed, then press and release the SET - switch. The current engine speed will be maintained. This action can be repeated as desired to a higher RPM value. The PTO set speed cannot exceed 2100 RPM.
  • Tap Down: Press and release the SET - switch to reduce the engine speed by increments of 100 RPM.
  • Coast: Press and hold the SET -switch to reduce the RPM by 200 RPM per second until the desired engine speed is reached or until the initial PTO standby speed is reached.
• RES +: When a PTO set speed has been achieved, press and release the brake pedal. Engine speed will return to normal idle speed. The PTO LED will flash slowly indicating the previous PTO set speed has been retained in memory. Press and release the RES + to resume the previous PTO set speed. The PTO set speed cannot exceed 2100 RPM.
  • Tap Up: Press and release the RES + to increase the engine speed by increments of 100 RPM.
  • Accelerate: Press and hold the RES + to increase the RPM by 200 RPM per second until the desired engine speed is reached or until the maximum allowable PTO set speed is reached.
