Control of hydraulic system and
hitch linkage of tractor
On tractors, the hitch linkage is controlled
by the extreme right lever of the distribu-
tor.
Working with implements, use only the lift
and floating positions of the lever.
It is forbidden to shift the lever to the
lowering position when working with
soil processing implements!
Use the lowering position only to control
the extension cylinders installed on a ma-
chine and intended to control positions of
tools (such as reel, haeder, sharers etc.) of
harvesting, sowing and other machines. If
after completion of a cylinder stroke, the
distributor lever does not return to the neu-
tral position automatically, bring it there
manually. And on the contrary, in case of
an early return of the lever, hold it with
hand to let the operation be completed.
