The PTO shaft will not rotate if either of the two switches is in OFF position.
The following table explains how the PTO operates at the two different (Manual & Auto) positions of the PTO
control switch with the PTO ON/OFF switch in the on position.

From the table above we learn about the safety features of the PTO.
If the monitor on the dash panel is blinking, the PTO will notify the driver that the PTO will not rotate
temporarily because the driver is off the seat, even if it is in the ON position. When the operator is
seated again in the driver's seat or the implement is lowered to the ground with the PTO lamp
flashing, the PTO can start to rotate momentarily.
The operator must use this blinking signal to clear the area around the tractor off
bystanders/onlookers as the rotating blades of certain implements can accidentally cause injuries to
the persons standing near the tractor.
The stopping of the PTO when the implement is lifted off the ground with the position control prevents
the damage to the implement or the PTO shaft.
Warning:
1. Working on hard soils, pavements with a rotary implement the PTO ON/OFF switch must be
put to the OFF position to stop the PTO from rotating, If this is not done the rotating blades of
the implement will push on the hard ground below and in turn push the tractor toward causing
accident which can lead to serious injuries or death.
2. Extra precaution must be taken to clear the area of bystanders/onlookers when using PTO
driven implements. The rotating blades of the implements can cause serious injuries on
contact. The PTO monitor flashes or the warning lamp sounds as follows. If the driver is
seated on the seat again or the implement is lowered, PTO will start to rotate immediately.
3. On no case the specified rotating speeds indicated by the implement manufacturer be crossed
as the same can lead to serious damage to the tractor/equipment and can lead to serious
injuries to persons around.
