Draft control - outer lever - Yellow quadrant
Type of work:
Plowing, subsoiling, heavy cultivation, soil engaging
implements
Lever positions:
Position Control (2,Fig. 60), fully up in TRANSPORT
position.
Response Control, in the SLOW position.
Operate the lift hydraulics using the Draft Control
Lever (1).
Entering work:
Move the Draft Control Lever to the DOWN position
to lower the implement into work. The implement will
start to penetrate as the tractor moves forward. The
further the lever is moved to the DOWN position, the
deeper the implement will tend to penetrate.
In work:
When the desired working depth has been obtained,
move the Adjustable Stop (3) back to the lever and
lock into position with the hand knob. The Draft
Control Lever can be moved slightly either side of
the stop to adjust for varying soil conditions. Set the
Response Control (Fig. 59) towards SLOW (-) but in
a position to allow adequately fast entry into work. If
the implement moves up and down erratically turn
the Response Control towards SLOW.
Leaving work:
On reaching the headland, raise the implement by
moving the Draft Control Lever back to the UP
position. Re-enter work by moving the Draft Control
Lever forward to the Adjustable Stop.

required implement height above the ground is
obtained. Set the Adjustable Stop (3) in line with the
