4.9.1.3 Controlled draft

(only for lifts with controlled draft function)
This is ideal for jobs that require steady draft to prevent engine strain and
reduce tractor slipping. (half-turn ploughs, disk ploughs, harrows, every kind of
rotary cultivator, etc.).
Controls:
- P Turned all the way to its (-) minus position.
- S allows work depth to be regulated based on the draft force needed and to
keep the tractor at its slip limit. Lower lever A to position 1, turn
potentiometer S until the implement reaches the required position but always
within the tractor's ground holding limit. Turn towards (+) plus, draft
decreases by limiting working depth. Turn it towards (-) minus, draft
increases and work depth is increased. After regulating draft, operate the lift
with lever A. When the implement lowers, it will be positioned for the draft
set.
- A:
Position 0 - Lever in middle position. The lift is in neutral. The implement will
hold at its current position.
Position 1 - Lever lowered. The implement will lower to the draft setting given.
Position 2 - Lever raised. The implement will be raised as long as the lever is
held upwards. When the maximum height is reached, a limit switch stops lift
raise. When the lever is released, it will automatically reset to position "0"
(neutral).
Regulating lift sensitivity
When the tractor is working under controlled draft conditions, lift sensitivity can
be regulated using oil volume regulation n.31 fig.1
• Turn the knob counter-clockwise to reduce lift sensitivity.
• Turn the knob clockwise to increase lift sensitivity.
4.9.1.4 Combined controlled position and draft
(only with controlled draft lifts)
This is ideal for jobs that require steady draft and to prevent work depth
exceeding the setting given.
Controls:
- P Allows implement height to be set at the required position.
Lower lever A to position 1, turn potentiometer P until the implement reaches
the required position. Turn towards (-) minus, the implement will lower. Turn
it towards (+) plus, the implement will raise. After regulating position, operate
the lift with lever A. When the implement lowers, it will be stop at the position
