OPERATION

7.10 Lift Float Kit (Optional)

Ground scrub flailing can be a slow tedious task requiring a high degree of operator concentration especially when working on a rough or rising ground. A hydraulic float kit is available which is mounted tap upwards through the inboard mounting hole of a bracket which is located and bolted vertically to the face of the lift ram base lug nearest the tractor. See Illustration. The small hose supplied with the kit connects one side of the tap to the base connection of the lift ram. The existing lift ram hose is then attached to the remaining tap connection.

In work, with the stop tap open, the flail runs along the ground automatically lifting and riding over bumps. Any shock loads are absorbed by the accumulator which is precharged with nitrogen to 600 PSI (41 Bar).

To obtain optimum working performance the lift control should be operated to take approximately fifty percent of the flail head weight off the flail roller. This is important as with too little weight on the roller, the flail head will tend to remain in the air after riding over a bump and leave areas of uncut material, while with too much weight on the roller the float will be inoperative. The ground will be scalped in places and increase flail wear, loss or damage to flails could occur.

To revert to hedge cutting or to use the flail without it running along the ground, the stop tap should be closed to isolate the accumulator.
