The quick couplings are located in the rear part of the tractor.
The following functions are available:
• Lifting and lowering with the float function.
• Position control.
• Draft control.
• Mixed position and draft control.
The instructions and controls described below refer to fig.20, where:
- P Position control potentiometer
- S Draft control potentiometer
- A Power lift lever
4.9.2.1 Lifting – lowering with float function
Use of the float function completely frees the power lift arms, allowing the
implement to freely move on the ground. This function is generally used for
ridging, hoeing and with all implements that must follow the contours of the soil.
This type of lifting mode allows use of independent single-acting hydraulics to
raise a trailer platform.
These hydraulics are controlled by the same lever as the power lift (A fig.20) and
operate when the power lift cylinders reach end of stroke.
Controls:
- P fully turned to the minus (-) position.
- S fully turned to the minus (-) position.
- A:
Position 0 – Lever in the intermediate position. The lift will be in the neutral
position and the implement will remain at a standstill in the position it has
reached.
Position 1 – Lever down. The implement lowers until it rests on the ground. In
this position, the implement will remain resting on the ground and will follow
its contours.
Position 2 – Lever up. Keep the lever up until the desired height has been
reached. The lever will return to the neutral position 0 when released.
Adjusting the up and down speeds of the power lift:
Use capacity regulator N° 1 fig.20 to adjust the up and down speeds of the
power lift.
• Turn the knob clockwise to slow the speed of the power lift as it moves up and
down.
• Turn the knob anti-clockwise to increase the speed of the power lift as it
moves up and down.
4.9.2.2 Position control
This operating mode is suitable for work where the implement must remain in a
controlled position, both in and out of the soil (diggers, scrubbers, mounted
fertilizer spreaders, side delivery rakes, side-rear mowers, etc.)
