OPERATION
5.1.
Attaching the mower to the tractor
CAUTION:
When mounting and dismounting the mower, there should be no persons in
between the machine and the tractor. Any accidental maneuvering with the
set may cause to crushing of unauthorized personnel.
CAUTION:
Manufacturer is not responsible for mower’s damage, if it is caused by
improper mounting.
Unmounting of the mower may cause the following damages:
-
bending of mower’s guards by the tractor,
-
damage of PTO shaft,
-
damage of the gear and other parts of the mower.
During operation check mounting of the mower.
The mower is attached directly onto hitch triangle which is mounted to tractor's front 3-point
linkage (hitch triangle, Cat. II is delivered as mower's standard equipment).
Mount triangle (1) on tractor's lower arms, connect with pins (2), and then secure with spring
cotters (3). Next install upper connector (4), connect with pins (5) and secure both with spring
cotters (3) (Fig. 9).

After the mower has been attached to tractor, check the balance and steerability of tractor-
mower set. To do it, weigh the set and after that drive on the weigher with only the rear axis of the
tractor (the mower must be in transport position – lifted upwards). If the pressure on the rear axis is
at least 20 % of the whole set’s pressure, it means the set is stable. If not, the rear axis should be
balanced.
After having mounted the hitch triangle on the 3-point linkage drive perpendicularly to the
mower, using upper strand set the hitch triangle so it is parallel to the machine's triangle (Fig. 10),
lift the 3-point linkage until the mower is in the air and the triangle in place. Secure the hitch
triangle with pin and connect it with spring cotter. Finally adjust the length of chains (it. 5.3).
