Head Float - Spearhead Excel 606 Handbook

Spearhead
Optional – Head float

Head 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 head float
To select head 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.
