Riding Mower Overview

Each series of riding mower has it's own method of
suspending the mower assembly. For checking and
adjusting the blade tracking, height of cut, side-to-side
level, and front-to-rear pitch on a given riding mower,
see the subsection that discusses the appropriate
series of riding mower.

Checking Blade Level—
All Mowers
Checking the blade level involves preparing a suitable
workspace and measuring the distance from one of the
blade tips to a level flat surface at the 12, 3, 6, and
9 o'clock positions.

Preparing the Workspace

Use a straight edge to verify that the workspace is flat.
Do not assume the floor is flat even if it appears to be
so. You will make measurements with a tolerance of
less than 3/16 inch (5mm) (Figure 13). A small dip in a
concrete floor may cause you hours of work trying to
find a problem that isn't there.

For smaller product a 4 by 8 foot sheet of 3/4 inch
plywood laid on the floor may assure you of a relatively
flat surface. It is rigid enough to give you a good

surface to measure from and will serve you for all
mowers up to 48 inches wide and with a wheel base
less than about 84 inches. For larger machines you
may need to find a larger level area to verify the blades
are at the correct level.
