BEFORE CARRYING OUT ANY OPERATION SUCH AS MAINTENANCE OR ADJUSTMENT ON
THE MACHINE, STOP THE TRACTOR ENGINE, REMOVE IGNITION KEY AND WAIT FOR
ROTATING DISCS TO STOP.
Cutting height
Maximum cutting height (80 mm / 3") (fig. 26) is achieved when the discs are parallel to the ground. Adjustment of
cutting height is achieved by altering the cutterbar tilt angle. This is effected by varying top link length (P) (photo
25) until desired cutting height is achieved. To minimize blade and disc wear, improve grass regrowth and get
maximum nutritive value from the crop, minimum cutting height should never be adjusted less than 30 mm
/ 1 1/4" (fig. 27).
