Adjustments
Note:
Disengage PTO, shut off engine, wait for
all moving parts to stop, engage parking brake, and
remove key before servicing, cleaning, or making any
adjustments to the unit.
Adjusting the Cutting Height
The cutting height of the mower deck is adjusted
from 1 inch to 4 1/4 inches (2.54 cm to 11.4 cm) in
1/4 inch (.64 cm) increments by adjusting the axle
position, number of spacers below the caster hub,
and number of spacers between blade and spindle.
Refer to the Cutting Height Adjustment table and
select a cutting height range in the left hand column
which corresponds to the range of cutting heights
you will most often be using. Adjustments within this
range can then be made by adjusting the number of
blade spacers between the blade and the bottom of
the spindle (this is a much easier adjustment to make
than adjusting axle position and number of spacers
below caster support hub).
Note that:
• For the best cut and discharge, place a minimum
of two spacers between the blade and the spindle.
• For highest quality cut, place all four spacers
between the blade and the spindle.
• If mulching kit is installed, the highest quality cut
can be obtained with 3 spacers between the blade
and the spindle (minimum is 1 for a good cut).
• When mulching leaves it is best to have fewer
spacers between blade and spindle.
Refer to the table and select desired cutting height
range. Refer to
Adjusting the Axle Position,
Adjusting the Number of Spacers below Caster
Support Hub,
and Adjusting the Cutting
Height with Blade Spacers and sections to make
adjustments make adjustment to obtain specific
cutting height.
