bolt for adjustment
of the width of the first ridge
Setting the optimum furrow width is of particular importance for reducing the working
resistance of the agricultural machinery and minimizing the degree of soil clumping
after ploughing. The operating width of a plough body must be adjusted according to
the weather conditions, terrain and the capabilities of the farm tractor. Indicated above
is the position of the actuator within the agricultural machinery and the direction of
its movement. Extension of the actuator reduces the furrow width, while the maximum
position of the actuator corresponds to the maximum furrow width.
4.6. Adjusting the first ridge
The width of the first ridge should correspond to the width of
the remaining ridges, but one should also take into account:
•
resultant compensation of the plough’s operating resistance,
• with wide tractor tyres, the width of the first ridge should
be reduced to ensure proper alignment of the front ridges,
• For a plough equipped with a furrow widener, the width of
the first ridge should be reduced by 13 cm compared to the
width of the remaining ridges.
After altering the working width of the first ridge, one may need to adjust the width of
the furrow.
