en-388 ADJUSTMENTS8.1 51 MARQUIS: HEIGHT OF CUT ADJUSTMENT________________________The cutting height is determined by the postion of thefront rolls in relation to the bottom blade, variation ofthis height is made by adjusting the front roll. a rangeof cut between 6mm and 27mm can be achieved withthe adjustments explained below.The height of cut bar [A] (Fig. 8.1a) is used toaccurately set the height of cut. The bolt in the heightof cut bar is positioned so that the head of the bolt ishooked over the lip of the bottom blade. The bar restsagainst both the front [C] and the rear [B] rolls.The measured hieght of cut would be from theunderside 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 positionit over the lip of the bottom blade. If it does not fit snugly, 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 rearlandroll.Pull out the pin [A] (Fig. 8.1b) on both sides of themachine and replace it in one of the other 3 holes(coarse adjustment).Placing the pin in the hole towards the front of themachine will increase the height of cut and towards theback of the machine will lower the hieght of cut.For fine adjustment the screw [B] should be turned.8.2 61 MARQUIS: HEIGHT OF CUT ADJUSTMENT_________________________The height variation is made by adjusting the front rollby means of a handwheel [C].To raise the height of cut, the roll has to be loweredandthis is achieved by turning the handwheel clockwise.To lower the height of cut, the roll has to be raised.Turnthe handwheel antoclockwise.To ensure that the height of cut is set correctly, tilt themachine back and place a straight edge across thefront and rear rolls. The gap between the bottom bladecutting surface and the straight edge should not beless than 6mm ( 1 /4in).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 damageFig. 8.2Fig. 8.1bFig. 8.1a
