4.2.2
Drive away operation of tractor
a. Release the hand brake handle (if any implement is linked, it must be lifted up first).
b.Step on clutch pedal all the way to the end, shift speed-changing lever to the desired gear.
If failed to shift into gear, release the clutch pedal a little, and depress it again for
engaging the gear.
c.Accelerate gradually, meanwhile release clutch pedal slowly to drive the tractor away from
rest.
d. Normally, low gear should be used for driving away operation.
4.2.3
Driving the tractor
a.
Selecting the proper gear
Proper gear should be selected to let the engine work with 80% of maximum power.
When rototilling, Gear I, II or III will be used. Gear IV or V will be used for the
power-driven harrow and plowing and towing operation and Gear VII & VIII for hauling
operation.
b.
In operation, it is prohibited to ride the clutch (i.e. keep foot on clutch pedal half depressed)
or to control speed with the clutch. Otherwise the clutch will get overheated, which will
cause premature wear-out of the friction discs because of friction disc slippage, and even
cause further damage to the release bearing, release levers and the release bearing seat as
well.
c.
In field operation, LH or RH brake may be singly used to reduce the turning radius.
When emergency braking, depress down clutch pedal and brake pedal at the same time,
NEVER step on brake pedal only, so as to avoid damage to the brake and other parts.
d.
Close hydraulic lock valve and disengage PTO shaft when the tractor is going to travel
for a long way with an implement mounted.
e.
When tractor works in the dry field, the user may install the rear wheel ballast (optional)
in order to make full use of the traction force. If the tractor is provided with the cabin,
then it is also OK not to install the rear wheel ballast.
4.2.4
Stop of tractor
a.
Reduce throttle to slow down the tractor.
b.
Step on clutch pedal, shift speed-changing lever to “Neutral” position.
a.
Depress brake pedal to stop the tractor, then release clutch and brake pedals, let engine
run idly at low speed and apply the parking brake.
b.
Lower down the implement attached.
c.
Never step on the throttle fiercely just before stopping the engine but let the engine run
idly at low speed for a while after the engine is unloaded so as to cool down the
lubricant and water, then pull out the engine stop lever to stop engine. Drain off cooling
water when ambient temperature is below 5
℃
and drain off fuel oil when ambient
temperature is below -5
℃
.
