link until loose. Final adjustment will be made later.
Refer to Figure 2-2:
3. With gloves on, carefully rotate each blade tip to the
position shown in Figure 2-2 on page 15.
4. At the front of the cutter, measure the distance from
blade cutting tip to ground surface. This distance is
known as the “Nominal Cutting Height”.
5. The tail wheel will need adjusting if nominal cutting
height is not at the preferred cutting height. Adjust
tailwheel per instructions on pages 16 and 16.
6. Repeat steps 1 to 5 until preferred cutting height is
achieved.
7. Set stop on tractor lift quadrant so cutter can be
returned to the same height.
IMPORTANT: The front blade tip should be lower
than rear blade tip by approximately 1". The cutter is
subject to continuous material flow under the deck if
therear bladeisat the same height or lowerthan the
front blade causing horsepower loss, grass clumps,
blade wear, and frequent blade sharpening.
