4. THE PREPARATION OF THE TRACTOR PULLING
4.1. NECESSARY TRACTION POWER
The power necessary for plough traction changes in the function of soil structure and working
conditions. The data in the table is informative. The GRÉGOIRE-BESSON dealer knows the
country very well where the plough is going to be used. He can give some advice not only in the
connection with the traction power but the optional possibilities of the required exceeded the time
work.
Number of plough bottoms
Average soil (15 to 30 %
clay)
Black land ( > 50 % clay)
4 plough bottoms 100 - 140 horse power 120-160 horse power
5 plough bottoms 140 - 180 horse power 160 - 200 horse power
6 plough bottoms 180 - 220 horse power 200 - 240 horse power
7 plough bottoms 220 - 260 horse power 240 - 280 horse power
8 plough bottoms 260 - 290 horse power 280 - 320 horse power
4.2. THE DISTANCE BETWEEN TRACTOR WHEELS
We blow up the rear and front tyres to the pressure specified by the manufacturer.
Follow the rules of the instruction and recommendations of the tyre producer. On the
both sides of the tractor the pressure should be the same for the plough to work on the
proper level.
In general it can be said that the plough with higher number of plough bottoms (> 6 plough
bottoms) with the growing of the tractor wheels distance the traction work will be better and better.
Besides if there is first furrow adjusting cylinder the plough can be adjusted to the tractor width (in
the case if we speak about tractor usage, or during participating in the traffic where the width must
be limited or more tractors are used with the same plough).
For the tractor going in the furrow in right
direction it is recommended that the center
of the front wheel should be in one line with
the center of the rear wheel. This way the
front driven wheel will not drag the furrow
side (gravel may damage the tyre side) so
the tractor will be easier directed as on the
left as on the right side.
