Hole to drill
1. Place baffle in the cutting chamber (Fig. 2).
Note: When installing bolts, the bolt heads
need to be on the inside of cutting
deck.
2. Install a bolt and nut into the one pre–drilled
hole (Fig. 1 and 2).
Note: When installing bolt into pre–drilled
hole, notice which hole it is installed
through the baffle (Fig. 1).
3. Install new mulching blades after the baffle is in
place and without anti-scalp cups (Fig. 1).
IMPORTANT: The sail part of the blades
(i.e., the turned up section) must face the
inside of the mower (Fig. 1).

Installation Instructions
5. To determine where you need to drill holes,
arrange the baffle in the mower as shown in
Figure 3. Rotate the center blade to ensure that
there is a 1/4” of clearance between the tip of the
center blade and the baffle.
Note: Use the center blade to determine the
location of the baffle.

Mulching Tips
Selecting The Proper Height-Of-Cut Setting To
Suit Conditions – Remove approximately one inch
or no more that 1/3 of the grass blade when cutting.
In exceptionally lush and dense grass you may have
to raise the height-of-cut setting another notch or
convert to side discharge or bagging operations.
Mowing In Extreme Conditions – Air is required to
cut and recut grass clippings in mower housing, so do
not set height–of–cut too low or totally surround
housing by uncut grass. Always try to have one side
of the mower housing free from uncut grass, allowing
air to be drawn into housing. When making an initial
cut thru center of uncut area, operate machine slower
and back up if mower starts to clog.
Mow At Pr
conditions you’ll need to mow every 4–5 days.
However, grass grows at different rates at different
times. Thus, in order to maintain the same
height-of-cut, which is a good practice, you’ll need to
cut more frequently in early spring; as the grass
growth rate slows in mid summer, cut only every
8–10 days. If you are unable to mow for an extended
period due to weather conditions or other reasons,
convert to side discharge or bagging options or mow
first with the height-of-cut at a high level; then mow
again 2–3 days later with a lower height setting.
Always Mow With Sharp Blades – A sharp blade
cuts cleanly and without tearing or shredding the
grass blade like a dull blade. Tearing and shredding
causes the grass to turn brown at the edges which
impairs growth and increases susceptibility to
disease.
After Operating – To ensure optimum performance,
clean underside of mower housing after each use. If
residue is allowed to build up in mower housing
cutting performance will decrease.
