Fig. 11 Correct way to put the first (1) pawl on the piston rod of the cylinder to adjust the working depth
of the machine.
Fig. 12 Incorrect installation of pawls on cylinder piston rod. Partial omission of the attachment of the pawls
to the cylinder results in uneven distribution of the forces acting on the piston rod and can lead to piston
rod buckling resulting in damage to the entire cylinder assembly. This kind of adjustment is
unacceptable!
The number of pawls on all shaft arm cylinders must always be equal!
The working depth of the discs is set according to the depth of the cultivator. The discs
must work on the surface to evenly level the soil behind the plough beams.
The SPEC HD cultivator elements can be adjusted in terms of angle of attack. The more
horizontal position of the coulters reduces working resistance and undercuts the stubble
with low loosening - recommended for compact soils with optimum moisture content and
soils of medium and low compactness (nut on the spring screw). The steeper position of
the coulter facilitates penetration and loosens the soil to a greater extent - recommended
for hard and dry soils. Note that as the screw twist changes, so does the strength of the
protection induction.
WARNING! It is forbidden to make adjustments to the machine while the
tractor engine is running.
The working speed of the SPEC HD cultivator under normal operating
conditions should be 8 - 12 km/h.
