Manual Extract: Auto PTO

This facility provides an automatic starting and stopping of the PTO in relation to the raising or lowering of the lift arms.
The height at which this occurs is pre-programmed by the operator.

To activate the Auto function, engage the PTO as previously described and then depress and hold the switch (1), for more than one second. The Auto PTO lamp on the switch will illuminate to confirm activation. With the 3 point hitch in the lowered position and the PTO engaged, the Auto lamp will remain on. Raising the implement will disconnect PTO drive and cause both PTO and Auto lamps to flash. Lowering the implement will re-engage PTO drive, both lamps will cease to flash and will remain illuminated. Depressing the Auto PTO switch again will de-activate the function and the Auto lamp will extinguish.

NOTICE: If the PTO is operating when the Auto function is de-activated, the PTO will continue to rotate until switched off using the main PTO control.

NOTE: The Auto PTO function is de-activated every time the key start is switched off but the current programmed on/off values will be stored in the memory.
