Arm Float
This is only to be used in verge mowing set up, it will reduce weight on the rear roller
allowing head to move more easily, following small changes in ground contours in a
forward motion, with the aid of a pre-charged gas accumulator.
Operating The Arm Float
To select arm float, first lower cutting head to the ground, disengage PTO and stop
tractor engine. To the back of the slew frame is situated the float on/off tap. Turn tap
in line for ‘on’ float, remote electric switching is optional. Main Lift control lever
should be operated to take a proportion of the flail head weight off the rear roller. This
is important, as too little weight on the rear roller will leave uncut areas of grass, too
much weight on the roller will cause scalping in places and increase flail wear and
damage. We strongly recommend the use of auto reset - break back.
When the head is pushed further out more weight will be applied to the accumulator
causing the head to drop, reset with control lever.
As the ground contours alter it is necessary to reset the pressure within the main lift
circuit as above, constantly raising or lowering control lever.
Debris Blower
Hydraulically driven fan from tractor external services, please quote tractor oil flow
when ordering (maximum 40lt per min).
Warning
Do not fold the machine up for transport before turning off the arm float.
And discharging the pressure from the lift circuit.
