Adjust Blade Pitch
IMPORTANT: Side-to-side deck heights
MUST remain even after completing pitch
adjustment.
NOTICE: Pitching the front of the blades
lower than the rear provides a balance

the deck rear to be pitched lower than the
front. Positioning the deck this way requires
more engine power but can provide better cut
quality.
1. Increase forward pitch:
