To operate Live P.T.O., start the engine, fully depress
the clutch and pull the P.T.O. selector lever, Figure 9,
rearwards to engage the P.T.O.
Set the engine speed at 1800 rev/min and release the
clutch pedal to the halfway position to actuate the P.T.O.
output shaft.
With a gear selected, fully release the clutch pedal to
run the tractor.
To stop the tractor, depress the clutch pedal to the mid-
position and to stop the P.T.O. output shaft depress the
pedal fully.
BELT PULLEY (where provided)
The belt pulley, which is driven by the P.T.O . output
shaft, should be installed as shown in Figure 10.
Prior to installation, remove the drawbar and drawbar
hanger to provide the maximum clearance for the drive
belt.
To install the belt pulley, remove the P.T.O. safety cap
and guard and the four bolts securing the check chain
brackets to the rear axle center housing. Install the belt
pulley on the P.T.O. shaft using the four bolts provided.
WARNING :
To avoid injury, always use a belt
guard whenever using the belt pulley.
l
Hang a chain or lean an iron bar against the tractor
to earth static electricity.
l
Start the engine and engage the P.T.O. The
recommended belt speed is 3000-3200 ft/min
(15.3-16.3 m/sec). To obtain this speed set the
engine speed at 2000 rev/min.
WARNING:
Never attempt to re-fit or adjust a
belt in motion. Never approach a moving belt
when wearing loose clothing. Apply the parking brake,
place both gearshift levers in neutral and block all four
wheels before operating the belt pulley.
HYDRAULIC SYSTEM
Your tractor is equipped with a hydraulic system
providing accurate and sensitive control over a wide
range of operating conditions.
Two distinct systems are incorporated
1.
Upper Link Draft Control.
2.
Position Control.
The type of control selected will depend on the type of
implement in use and the operating conditions.
Draft Control
is most suitable for mounted
implements operating in the ground. Changes in the
working depth or soil resistance cause the draft loading
on the implement to increase or decrease. This change
in draft loading is sensed through the top link of the
three-point linkage and the hydraulic system responds
by raising or lowering the implement to restore the draft
loading. In this way a uniform draft load is maintained
on the implement. The system responds to both upper
link compression and tension loads and is, thus,
described as a double-acting system.
Position Control
provides accurate and sensitive
control of implements such as sprayers, rakes, mowers,
etc., that operate above the ground. Position Control
would not normally be used with ground engaging
equipment unless it is essential to maintain a constant
depth regardless of the draft load.
The tractor has a dual lever system, i.e., separate levers
for Draft and Position Control functions. See Figure 11.
The Draft and Position Control levers are used to raise
or lower the three-point linkage (and implement) to the
required height or working depth.
To Operate the Belt Pulley
l
Fully raise and secure the lower links.
l
Align the tractor with the equipment to obtain full width
contact on both pulleys without the belt contacting any
other part of the tractor or equipment.
l
Apply the parking brake and block all wheels to prevent
tractor movement due to vibration.
