3.2.2.4 Verify that the protection rotates freely and secure it with the appropriate chain. Remove the support from the
PTO shaft.
3.2.2.5 Connect the headstock top link (C), securing it with the appropriate pins and split pins, and use the tractor
adjustable top link to adjust correctly, making sure that the upper surface of the flail mulcher is parallel to the
ground. This is very important in order to obtain parallelism between the rotor shaft and the tractor power take-off.
3.2.2.6 Operating in these conditions limits the stress on the power take-off and prolongs the working life duration of
the PTO shaft and the flail mulcher itself.
3.2.2.7 The correct position of the tractor/flail mulcher unit is such when the flail mulcher is at a distance from the
tractor so that the PTO shaft does not extend beyond 5-10 cm from the maximum closing position.
3.2.2.8 Connect the mulchers hydraulic hoses, which control the rear hood, to the appropriate connectors on the
tractor, see Figure 3.3.
3.2.2.9 Engage the PTO and accelerate up to a minimum of 400 rpm. Then test lift the flail mulcher to verify proper
operation.
