HYDRAULIC LIFT SYSTEM
WARNING
Before operating any of the controls
ensure that all pedestrians are clear of
the tractor and Its implements.
The hydraulic system combines the
tractor and implement into one unit with
the implement hydraulically controlled.
This system provides these five functions:
1.
Draft control
, (1 Fig. 14) operates in
the Yellow (Draft ) range of the quad-
rant and is used to control the working
depth of soil-engaging implements.
The further the lever is moved to the
‘DOWN’ position, the deeper the imple-
ment will tend to penetrate the ground
and, conversely, the nearer the lever
is to the ‘UP’ mark, the shallower the
implement will tend to work.
2.
Position control
, (2 Fig. 14) oper-
ates on the Red (Position and Trans-
port) and Constant Pumping range of
the quadrant. The Red sector is used
to control the working height of im-
plements above the ground. When the
lever is in the Constant Pumping range
shield to be bolted to the tractor when
pull-type PTO driven equipment is be-
ing used. A hole (2) is also provided for
the PTO driveline shield chain.
4. If PTO driven equipment is connected
to the swinging drawbar, the drawbar
must be set so that the horizontal dis-
tance ‘A’ between the end of the PTO
shaft and the pin hole in the end of the
drawbar is 356 mm, (14 in) if using the
six spline 540 rev/min shaft.

ATTACHING TO THE PTO SHAFT (Fig.
13)
1. Unscrew and remove the PTO cap and
store it in the tool box for future use.
2. Attach the PTO shaft to the splined
shaft on the tractor. Ensure that the
locking device has securely retained
the shaft.
3. Ensure that all the guards are in place.
A slot (1) is provided in the top of
the PTO guard to enable the driveline
