1. INTRODUCTION
It is important that the cutting unit is correctly relieved to ensure perfect operation in
the field and to reduce the risk of damaging the cutter bar.
If the cutting unit is blocked, stop the tractor engine, activate the parking brake and
wait until the revolving parts have stopped before removing the foreign matter.
When working with a side-mounted mower, never drive too fast along slopes and
hillsides as you should be able to avoid large stones, ditches and other obstacles
which may cause the tractor to overturn.
Also remember to adjust the speed for sharp turns on hillsides and for lifting the
machine in the three-point linkage.
The side-mounted mowers have a spring-loaded safety release which secures the
directional stability of the tractor and reduces damage in case of collision.
Check that the safety release can be released and that it is not blocked.
If the vibrations or the noise of the machine increase considerably during the
operation, stop working immediately. Do not continue the work until the fault has
been corrected.
MAINTENANCE
Always make sure that the used spare parts are tightened to the correct torque.
When replacing parts in the hydraulic system always make sure that the cutting unit
rests on the ground or the lifting cylinders are blocked.
Hydraulic hoses must be checked by an expert before use, and after that minimum
once a year. If necessary, they must be replaced. The working life of hydraulic hoses
should not exceed 6 years, including maximum 2 years of storage.
When replacing, always use hoses which comply with the requirements stated by the
manufacturer. All hoses are marked with date of production.
MACHINE SAFETY
All revolving parts are balanced by JF-Fabriken by means of a special machine with
electronic sensors. If it turns out that a part still has an unbalance, small
counterweights should be mounted.
As the discs run at up to 3000 RPM, even the slightest unbalance will cause
vibrations which may lead to fatigue fractures.
When replacing blades, both blades on the disc in question must be replaced as not
to create an unbalance.
During the season check daily that no blades, carriers or bolts are missing. If any of
these are missing, mount new parts immediately.
Clean caps (if mounted) and flow intensifiers of earth and grass regularly.
Friction clutches must be “aired” regularly to ensure that they do not get rusty.
