MOWING HEIGHT ADJUSTMENT
The mowing height is determined by three factors: the
mount position of the mower deck, the number of blade
spacers above the spindle and the number of caster
spacers above the caster arm.
Refer to the chart to the right for the correct settings to
obtain the desired height of cut. Remember, the “Blade
Spacers” and “Caster Spacers” columns refer to the
number ABOVE the spindle and caster arm.
