Lift Float (Option) - Tiger RBM16 Operator's Manual

LIFT FLOAT (Optional Extra for Ground Work)
Work without lift float requires far more concentration and input from the operator to
quickly react and re-adjust to the ground contours often resulting in patches of higher cut
material where the head is cutting too high and 'scalping' of the ground where it is cutting
too low – in the case of the latter this can lead to increased flail wear, damage or even loss
of flails.
The Lift float feature is an optional extra for use during mowing work. When the function is
activated the pressurised accumulator(s) work in conjunction with the valve and lift ram to
take a proportion of the flailheads weight off the flail roller allowing the head to
automatically follow the natural contours of the ground; this produces a cleaner more
uniform cut without the need for constant operator re-adjustment.
Operation of the lift float function is as follows: with lift float switched off, position the
flailhead approximately 1m clear of the ground before switching the float function on to
charge the accumulator(s) – the arms may drop at this point depending on the current
level of retained pressure. Lower the flailhead into the work position, release the lift control
and proceed to work. NOTE: occasional operation of the lift function will be required when
working on downhill or uphill slopes and when reaching in or out in order to replenish the
oil level within the accumulator(s) to retain optimum float capability.
Without Lift Float
- Will require constant operator input.
Lift float operation is controlled via the auxiliary electric switch supplied with the kit. The
switch will need to be mounted in a suitable convenient location in the tractor cab.
Lift Float Power Supply
The supply cable from the poppet valve solenoid must be connected into the tractors
ignition system - the brown lead is positive and the blue lead is negative.
With Lift Float
- Automatically follows ground contours.
