  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 accelerator pedal to close the clutch and engage the PTO in mobile mode. The PTO may be operated with the transmission in reverse, neutral, 1st, or 2nd gear only.

    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 down 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.
