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.
