or a proper operation of the hydraulic and mechanical
relief system the line between the tractor’s three-point
connection’s arm pivot point and the mower
attachment bolt in the working position shall form a
positive angle (1) with the surface level, never a
negative one (2).
3.2 Preparing the hitch of the discharging springs
To adapt the cutter bar to uneven ground its weight
must be reduced to 150 kg.
For discharge two springs are placed on the mower's
hitch and on the front hitch framework.
If the hitch does not ensure the 300 mm lift of the
cutter bar, it must be replaced.
If the recommended angle of the feder hitch on the
front hitch framework is not achieved, it must be
adequately completed.
Note:
If your tractor allows the hydraulic discharge of the
front hitch, no discharge springs are needed.
Adjust the discharge to 150 kg.
–
Nobody is allowed to stay between
tractor and machine when lifting or
lowering the hydraulics.
