Adjusting the Height of Cut

You can adjust the height of cut from 2.5 to 15.8 cm
(1 to 6 inches) in 6 mm (1/4 inch) increments by
relocating the height-of-cut pin into different hole
locations.
1. With the engine running, push back the deck-lift
switch until the mower deck is fully raised, and
release the switch immediately as shown in
Figure 26.
2. Rotate the height-of-cut pin until the nub on
it lines up with the slots in the holes in the
height-of-cut bracket and remove it
3. Select a hole in the height-of-cut bracket
corresponding to the desired height of cut, insert
the pin, and rotate it down to lock it in place
(Figure 26).
Note:
There are 4 rows of hole positions
(Figure 26). The top row gives you the height of
cut listed above the pin. The second row down
gives you the height listed plus 6 mm (1/4 inch).
The third row down gives you the height listed
plus 12 mm (1/2 inch). The bottom row gives you
the height listed plus 18 mm (3/4 inch). For the
15.8 cm (6 inches) position, there is only 1 hole,
located in the second row. This does not add 6
mm (1/4 inch) to the 15.8 cm (6 inches) position.
