3.7.4 PLANTING UNIT EXCLUSION
Switch off the tractor and remove the ignition key.
Raise the single seeder from the ground as follows:
- Turn the winged nut (1 Fig. 32) of the hooking lever anticlockwise.
- Lift the planting unit using the lever (2, Fig. 33).
- Press and hold down the sleeve (1 Fig. 34) in the direction
indicated by the arrow, push forward while turning the ring nut
(2 Fig. 34) until the iron pin comes free.
- Pull the sleeve back as far as it will go (1 Fig. 34).
- To render the drive operative again, push the sleeve forward
and lock the ring nut again against the iron pin.
IMPORTANT!
Pay the greatest attention to the couplings of the cardan shafts
(A, Fig. 34) and follow the position of the crosses.
3.7.5 PLANTING UNIT TRANSMISSION
Each case is equipped with a safety pin which breaks (1 Fig. 35)
when the rotating of the seeder plate is forced or jams as a result
of foreign bodies entering the distributor (paper, string etc.) Should
this occur, pour the seeds out of the container, check and clean
the distributor, check the plate pegs and replace the safety pin.
Each transmission shaft has a torque limiter with a sound alarm
(3 Fig. 35) that, when the pin breaks (1 Fig. 35), signals the anomaly
or breakdown that has occurred in the distributor. If this happens,
stop at once and remedy the situation; remove the broken pin
and replace it (use the pin punch supplied).
IMPORTANT! Do not use metal pins. Always use original spare
parts.
WARNING
! Do not over-tighten the screws holding the case (2
Fig. 35). It should be able to oscillate.
