9.6.3. ADJUSTMENT OF THE HYDRAULIC COMPENSATION CYLINDER (Option)
The hydraulic compensation cylinder (GRÉGOIRE-BESSON patent) provides transmission of the
tractor draw power to the bottom mounted levers. Because of that the draw force of the tractor
ameliorates due to the optimal loading distribution.
A simple hydraulic cylinder (26) connects the upper part of the reverse head to draw equipment with
the help of 110° cardan axle. A hydraulic accumulator (27) which has pressure checking manometer
(29) and a float needle valve (30) can be found here.
¾ Perform the adjustment accordingly to the following procedure:
¾ Adjust the length of the third point put the cross-bearer into the vertical position (white dotted line),
when the plough is working under the normal conditions.
¾ Connect the tractor with the cylinder hydraulic flexible pipe,
¾ Open the float needle valve (30) 2 to 3 turning,
¾ Hydraulic circuit put under the pressure and increase the pressure (green line of the manometer
(29)). The purpose is that during the plough work, the force should not interact on the third point
of the pin (28) The proper pressure will be got if the pin is unloaded (28) . Notice that the pressure
is about 100 bar and it is important to check the pin free rotation.
¾ Close the float needle-valve back (30) if the condition of the balance is got.
ATTENTION
: Do not forget to decrease the pressure to 0 bar. If the pressure
is not eliminated the disengagement is difficult to perform and the cross-arm
can fall on the ground. Because of that you may be injured that leads to
amputation or even death.
