Once you have obtained the desired depth. Check that the pins on the tractor and the pins on the
plough are all equidistant from the ground. And the three-point hitch pin on the plough is
approximately 1-5 cm higher than the three-point hitch-pin on the tractor.
ADJUSTMENTS
Before starting work with implement. You must perform the following adjustments:
1.
ADJUSTING THE IMPLEMENT WIDTHWISE:
The purpose of the adjustment is to ensure that
the implement is level with the ground horizontally so that all the discs work at the same
depth. Perform this adjustment with adjustable tie rod of the right hydraulic power lift arm.
2.
ADJUSTING THE IMPLEMENT LENGTHWISE
: The purpose of this adjustment is to ensure that
the implement is level with the ground lengthwise so that all the discs work at the same
depth. Perform this adjustment by lengthening the adjustable top link arm of the tractor.
3.
ADJUSTING THE WORKING DEPTH
: Perform this operation with hydraulic control lever of the
tractor power lift, or by adjusting the depth wheel.
4.
ADJUSTING THE COULTER WHEEL:
The purpose of this adjustment is to equalize the thrust of
the implement from the discs reacting to the conditions of the ground, which tends to make
the tractor pull to the right. Perform this adjustment by changing the angle of rear coulter
wheel
(Fig. 2) Ref. C
as follow.
•
Change the angle of the drawbar
(Fig. 3) Ref. B
by selecting another slot
Ref. A
to lock it.
•
Turn and/or move the eccentric axle
(Fig. 2) Ref. D
on which the wheel is mounted. Remove
the lock plate first.
Note:
If the coulter wheel is pitched too far, it could shorten the life of the bearings.
5.
ADJUSTING THE WORKING WIDTH OF THE FIRST DISCS:
The purpose of this adjustment is to
ensure that the implement works at the same width during each pass of the tractor. Perform
this adjustment by moving the drawbar to the right or left (Fig. 3) Ref. B. Once you have
made this adjustment, make sure that the stabilizer chains of the lower lift arms allow the
implement to sway from side to side approximately 5-8 cm.
Note: If moving the drawbar is not enough to adjust the working width of the first disc. Change the
tread of the tractor.
6.
ADJUSTING THE COULTER WHEEL SPRING:
The purpose of this adjustment is to ensure that
the disc is correctly loaded
(Fig. 4) Ref. C,
to allow it to penetrate the soil up to the circle,
thus creating an effective lateral support on the wall. Make this adjustment with the spring
(Fig. 4) Ref. A
, loosening first the lock nut
Ref. B
and then tightening it again once you have
made the adjustment.
