Mounting the mower on hitch triangle, cat. II
WARNING
For front 3-point linkage lifters with forced pressure (cylinders of front lifter
are under pressure during lowering) there is a risk that the machine is
damaged when being lowered. Excess pressure of the mower on the ground
may cause damage to the mower's hitch, damage to the entire machine,
excess stretching or damaging the support springs.
After the mower has been attached to tractor, check balance and steerability of tractor-mower
set. To do this, calculate to formulas given in the appendix or weigh the set, and then drive on the
scales only with front 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, rear axis should be balanced properly.
5.2.
Mounting PTO shaft
Prior to commencing operation, examine and adjust length of PTO shaft, which is designed to
mount machine on tractor. In some cases it is possible, that the shaft is too long and therefore needs
to be shortened, so that there is adequate tolerance for the shortest possible distance between
tractor’s shaft
O
and machine’s shaft
P
.
Shaft length should be adjusted individually for tractor, on which the machine is mounted.
Mount the PTO shaft so that the end with friction
clutch is on the mower's side.
Lift the mower on the 3-point linkage to its
maximum and mount the support springs so that,
when the mower is lowered on the ground and is
level with the tractor, the spring stretches from 50
cm to 64 cm.
It is advisable that the spring dimensions fall within
70 x 45 cm.
Secure the hitch triangle
with pin and connect it
with spring cotter.
Set the mower's inclination for cutting
height and lock the upper strand
against disconnection.
