Instructions and adjustment of the harrow
All fundamental adjustments must be carried out on a plane surface with the
harrow attached to the tractor and the wing sections lowered.
Attaching the harrow
Euro-Tiller is attached to the fixed tractor drawbar. Attach the
hydraulic hoses. Please note that the hoses with blue dust caps are
for lifting the harrow, and the ones with yellow dust caps are for
wing folding and leveling bar.
Adjusting the top link of the harrow
Lift the middle section just enough to lift the harrow tines from the
ground. Using the top link, adjust the middle section until it is
parallel to the ground. Remember to tighten the lock-nut. The top
link must be greased thoroughly so that fine adjustments are easily
carried out.
Adjusting the support wheels
When the harrow is parallel to the ground, the support wheels must
be adjusted.
The working depth is controlled by 3 hydraulic cylinders which are
series connected in a master-slave system.
To ensure an even depth across the entire working width, the
1
cylinders must be bled, reset and adjusted in relation to each other in
the following way:
Raise the harrow all the way up, so that the cylinders are fully
extended, and hold the lever in this position for approx. 20 seconds.
In this position, the cylinders' valves allow oil to flow through the
system and bleed the air out, while simultaneously resetting them.
This operation should be repeated for a few seconds when attaching
the machine to the tractor – after unfolding the wings but before
adjusting the harrow. It should also be carried out a couple of times
during the working day.
Make sure that none of the cylinder pistons are detached when
carrying out adjustments. Position the stop of the master cylinder so
that the harrow tines are lifted from the ground. Adjust the middle
section vertically to align it with the wings by shortening /
lengthening the piston rod (pos.1). If this is not sufficient, the same
procedure can be done on the slave cylinders. Be careful not to turn
too much.
The procedures mentioned above are fundamental: the harrow must
be fine adjusted in the field to ensure a perfect result. The earthworks
