locking catch
In practice, locking catch 6 should be taken out of both stabilisers, and the implement attached to the
three-point linkage. In order to take out locking catch pulling the snap fastening backwards. When the
implement is appropriately set, rotate sleeve until openings in sleeve corresponds with openings of free
spade terminals. Lock locking catch through opening C and secure with snap fastening.
With such a setting the stabilisers are locked as a rigid assembly and the implement is secured
against swinging equally during work as in transport.
In certain conditions or during work with such implements as ploughs etc, allowing sideways
movement of three-point linkage and implements may be indicated.
If locking catches 6 are taken out and set in oval opening B in the middle of the sleeve1, movement
shall be possible sideways to a limited angle or to opening A (pin shall act as a block, limiting angle of
swing).
ATTENTION: When setting the length of the stabilisers, especially in positions allowing swaying,
ensure that there is no possibility of contact between tyres and stabilisers or lower arms.
For example if tractor is working with plough, make the following three-point linkage adjustment:
•
during ploughing the tractor (normally) has the right wheels in the furrow, level the plough frame
(shortening or elongated right hanging rod), because in relation to the field surface, the tractor is tilted to
the right side;
•
so that the depth of work of the first and the last plough body shall be the same it is necessary (after
levelling) change the length of the top link using turning lever 1 (Figure 5-14) after unscrewing locking
nut 2. After adjustment tighten locking nut.
During travel of tractor with suspended machine (implement) for greater clearance (under the machine) one
may shorten top link.
