3.3 Adjusting the Compensating Spring
for the cutterbar
The three compensation springs adapt the pressure
exerted by the cutter beam on the ground below to local
conditions. In the interests of the turf, the cutter beam
should be provided with enough load compensation to
prevent jumping and subsequently leaving marks in the
ground. To make the appropriate adjustment, set the
disc mower to transport position, ensuring that the
transport lock (6) is engaged.
In this position, the compensation springs (2+3) of the
cutter beam can be taken off the pin (1), making it
possible to change their length. Shortening the length
means that the load compensation of the cutter beam is
greater.
The compensation springs (4) can be adjusted at the
spindle (5). Springs 2 and 3 provide load compensation
for the cutter beam, particularly on the outside. Spring 4
provides more load compensation on the inside.
After the compensation springs have been mounted,
resecure them on the pin with the hinge clip and washer
to prevent them slipping off.
3.5 Basic setting of the tractor lower
link arm
The best working height of the lower link arms is
achieved when the bracket (1) is fitted in the slot (2)
with a distance of a = 90 mm. This guarantees that the
mower unit will be able to adapt to uneven ground.
When preparing for turning, the cutterbar is simply lifted
by means of the hydraulic cylinder fitted to the disc
mower.
3.4 Adjusting piece for lifting cylinder
and flotation spring
The lower bearing bolt for the lifting cylinder and the
flotation spring must be locked in the correct position on
the different mower types. This adjustment is performed
at the factory and must not be changed.
Bolt (1) must be installed through lever (2).
Basic setting: distance "a" = 80 mm
distance "b" = 60 mm
