After detachment of the cutter its supporting feet must be extruded properly and locked against
loosening. This supporting frame is designed for keeping stability after putting the cutter aside.
Cardan Shaft Adjustment
Before use it is necessary to check up cardan shaft adjustment as to its proper length. The cardan
shaft length must be always adapted to the given tractor type.
Check up the cardan shaft length as follows:
-
couple the cutter in the top and bottom draw rods of the tractor three-point linkage,
- lift up the linkage (for adjustment the
cutter must be lifted in its top position)
- mark the position of the telescopic guard
edge,
- having coupled and locked the machine
to the tractor, connect the cardan shaft
(extend it as necessary),
check up clearance between the guard edge
and its previously marked and retracted
position: it should exceed 200 mm,
-
let the linkage slowly sink in its bottom position (supporting feet frame in contact on the
ground),
- let the cutter arm sink in its bottom position with the cutting head hinge as close as
possible to the tractor (hydraulic cylinder fully extruded),
- swing out the jib to the left or to the right in its utmost position.
The bottom position is in fact the utmost position in which the cutting head can
reach 600 mm (max. operating depth). For
this purpose it will be useful to have
the machine standing on the edge of a loading
ramp. In this case it will be
possible to reach the real bottom position.
Again check up clearance between the guard
edge: min. clearance should exceed 20 mm,
see fig.
If not, the cardan shaft should be shortened
accordingly, see instructions of the cardan
shaft manufacturer. Otherwise it may bring
damage on the shaft or even on the tractor.
