HITCHES
E461 X463

FRONT THREE-POINT HITCH
It is designed for coupling of front-carried
faming mechanisms and implement of
category II according to ISO.
When transporting a carried
implement it is always necessary
to secure the hitch lifted position
hydraulically using the valves that are
located on the left side of the tractor
above the front axle.
This hydraulic locking is recommended
even in case that there is not coupled
any mechanism to the three-point hitch.
ADJUSTMENT OF LIFTING SPEED OF
THE FRONT THREE-POINT HITCH
Before commencement of work with the
implement attached to the front three-
point hitch it is recommended to adjust
the throttling valve (3) so that the time
necessary to lower the implement from
the highest to the lowest position is 1 to
1.5 second. Rotation of the valve body
counterclockwise (in direction of the ar-
row) the lowering speed increases. Dur-
ing adjustment the front hitch valve lev-
ers shall be in horizontal position.
