10 ADJUSTMENTS
10.1 51 MARQUIS: HEIGHT OF CUT
ADJUSTMENT
The cutting height is determined by the position of
the front rolls in relation to the bottom blade,
variation of this height is made by adjusting the front
roll. A range of cut between 6mm and 27mm can be
achieved with the adjustments explained below.
The height of cut bar (A Fig.10.1.1) is used to
accurately set the height of cut. The bolt in (A) is
positioned so that the head of the bolt is hooked
over the lip of the bottom blade. The bar rests
against both the front (C) and the rear (B) rolls. The
measured height of cut would be from the underside
of the head of the bolt to the surface of the setting
bar.
It is important when using the bar to set the bolt to
the desired height of cut first and then to try to
position it over the lip of the bottom blade. If it does
not fit snugly then the front roll will require
adjustment.
This procedure should be carried out at both ends of
the bottom blade in order to set it parallel to the rear
landroll.
45cm and 51cm machines (Fig.10.1.2)
Pull out the pin (A) on both sides of the machine and
replace it in one of the other 3 holes (coarse
adjustment). Towards the front of the machine will
increase the height of cut, towards the back of the
machine will lower the height of cut. For fine
adjustment the screw (B) should be turned.
10.2 61 MARQUIS: HEIGHT OF CUT
ADJUSTMENT
The height variation is made by adjusting the front
roll by means of a hand wheel (C).
To raise the height of cut the roll has to be lowered
and this is achieved by turning the hand wheel
clockwise.
To lower the height of cut the roll has to be raised.
Turn the hand wheel anticlockwise.
To ensure that the height of cut is set correctly, tilt
the machine back and place a straight edge across
the front and rear rolls. The gap between the bottom
blade cutting surface and the straight edge should
not be less than 6mm. Check the setting at both
ends of the bottom blade.
NOTE: The front roll should never be set so that the
bottom blade is pressing on the turf; this will
damage the spiral cutters, bottom blade and the turf.
