10. If measurements are out of range, raise
the low side of the deck using the height
adjusters on the deck lift brackets (see
figure 15). Be sure to raise the deck
evenly to keep the deck level side to
side.
NOTE: Pitching the front of the blades lower
than the rear provides a balance between cut
quality and the power needed to cut grass.
Certain cutting conditions require the deck to
be pitched with the rear of the blades lower
than the front. Heeling the deck this way
requires more engine power but can provide
better cut quality.
11. Remove the blocks from under the deck.
