Power Takeoff (PTO) Governor

SD DM 10.04.01

Front Engine Power Take Offs (PTO) are devices used to tap into engine power to run auxiliary devices. Common uses are vehicles with hydraulic pumps which power additional equipment. The following instructions are general guidelines for operating a PTO.

  1. Set the parking brake. Shift the transmission to neutral.
  2. Press the dash PTO switch. Release the switch when the light begins to blink. When the light comes on steadily, the PTO is engaged and ready to operate. In stationary mode, the vehicle must remain in neutral with the parking brake set.
  3. To activate the mobile mode, shift from neutral to reverse, 1st, or 2nd gear. The clutch will open and the PTO will disengage for a moment.
  4. Touch the throttle pedal to close the clutch and engage the PTO in mobile mode. The PTO may be operated with the transmission in the following gears only: R-N-1-2.

    5. Note: Do not attempt to change gears while the vehicle is moving. The transmission will ignore the request.

  5. To end the mobile mode, bring the vehicle to a stop. The clutch will open and shut off power to the PTO.
  6. To resume stationary mode, shift to neutral. The PTO will engage.
  7. To end stationary mode, press the dash switch. When the light in the switch goes out, power to the PTO is shut off. Shut down the engine.
