2 MOUNTING BEHIND THE TRACTOR
- Adjust the tractor 3 point hitch lower arms at equal height.
The linkage bars (fig. 4) can be fitted to the headstock in two
positions. Position
ensures the closest possible position of
the ROTERRA power harrow behind the tractor.
- Mount the linkage bars, if possible, in position
. It
ensures the closest possible position of the ROTERRA
power harrow behind the tractor which leads to a more
favourable distribution of weight than position
.
- Fit the lever arms to the linkage pin.
- Mount the tractor top link to the machine by means of a
category II top link pin.
It is recommended that the top link on the tractor side is
fitted in the highest possible position whereas on the
ROTERRA power harrow side the lowest hole of the
headstock should be used. This will prevent the machine
from tilting forwards during lifting which reduces non-
uniformity in the drive. This is especially important if a
second, PTO- driven machine is coupled to the ROTERRA
power harrow.
- Top link length to be adjusted in such a way that the
horizontal position of the ROTERRA power harrow during
operations is ensured.
- Secure the tractor lever arms with stabilisation chains or
rods to avoid lateral movement of the machine.
- Check if the PTO shaft telescopes smoothly.
- Fit the PTO shaft to the tractor PTO shaft.
At first assembly or use of another tractor: check the
minimum and maximum overlap of the PTO shaft halves.
(Consult the instruction supplied with the PTO shaft.)
- Fit the safety chain of the protection tube to a rigid part
of the tractor.
