2.14.7.2 Power Take-Off (PTO) Shaft Use (with a dual-function clutch)
Power for the PTO shaft is switched on and off by a 2-stage clutch, the PTO disengagement control handle and
the power output gear shift knob on the left rear of the gearbox. When the power output disengagement control
handle is pushed downwards from the front position, the control lever pushes the engagement sleeve in the
gearbox back. The PTO is engaged and disengaged with a reverse movement. Push the PTO gear shift handle
forward for a high-speed shift and pull the handle backward for a low-speed shift. The procedure is as follows:
•
Remove the traction frame and the power output cover, then install the required farm machinery.
•
The power output gearshift handle is set in the required gear.
•
Step on the clutch pedal to the lowest position to disengage the power output clutch. Then push the power
output clutch disengagement control handle to the "engaged" position.
•
Release the clutch pedal slowly. First throttle down to run at low speed and check if the operation is
normal, and then start operating.
•
When short-time repetitive activity in one place is needed, it is necessary to step on the clutch pedal lightly
to disengage the main clutch. At this time, power for the tractor gearbox is disconnected, the tractor stays in
place, however, the farm machinery in the rear is still working normally.
•
When you need power output, the power output operation handle should be in the release position, and the
cover for the power output shaft should be remounted.
WARNING: When transporting farm machinery over long distances, the PTO control handle should be
pushed to the "disengaged" position to power off and prevent personal injury and/or the farm machinery from
being damaged.
2.14.8 Electrical Equipment Usage
The electrical system for the series XT tractor is a 12V negative ground system. For components and circuit of
electrical system, see Diagram 2-30
2.14.8.1 Battery
The battery is used to store the alternator energy. When the alternator does not work or runs in low speed, the
stored energy can be provided to the power-using equipment and as a secondary short-term power supply for an
overload.
•
Series XT tractors use a maintenance-free battery.
•
You should clean the dust and oil stains on the battery cover to avoid electric leakage. Check if there are
any cracks and leaking electrolyte fluid. Good contact between the poles and the conducting wire is vital.
The air vent in the plastic cover should be smooth to avoid an explosion.
•
Starting time shouldn't exceed 5 seconds each time to prevent battery drain.
•
If the tractor is not used for a long time, the battery should be removed and maintained.
