Other Model Specific Information
Although the Rolliflail group of flail mowers are rear mount as built, it is possible to turn them into front mount
machines by reversing the headstock. See Figure 1.6
Figure 1.6
IMPORTANT!
Before investing time in reversing the headstock, check that the rotation direction of the tractor
front output is opposite that of the tractor rear output. (
Note
: Rotation direction is defined by the
Spearhead PTO rotation convention, see section 1.3). Failure to check this first, may produce no rotor
motion when changed because the gearbox overrun operates.
1.5.1
Reversing The Headstock For Front Mount Operation
Ensure that the machine is de-mounted from the tractor and standing on firm level ground within reach
of lifting equipment.
The machine is normally supplied configured for rear mount and 540rpm PTO drive, see Figure 1.8.
Before disconnecting the headstock clamps measure and record the distance from the headstock to
the drive end plate to ensure it is put in the same location when reversed.
Support the Headstock in readiness to lift the Headstock clear. Be prepared, once disconnected, the
headstock support may rotate independently of the headstock.

WARNING!
Only personnel experienced in lift and hoist operation should be involved in lifting
machines.
