Side Discharge or Mulch Grass
Warning
Step
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in place,
you and others are exposed to blade contact and
thrown debris. Contact with rotating mower
blade(s) and thrown debris will cause injury or
death.
• Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
• Never put your hands or feet under the mower.
• Never try to clear discharge area or mower
blades unless you move the power take off
(PTO) to disengage and turn the ignition key to
off. Also remove the key and pull the wire off
the spark plug(s).
Ensure the mower has the hinged grass deflector that
disperses clippings to the side and down toward the turf,
while in side discharge mode.
To mulch grass clippings, the baffles must be installed into
the mower as shown in the following steps.

Removing the Existing Blades
Parts needed for this step:
None
Procedure
1. Remove the existing blades from the spindles (Fig. 1).
Note: Save the blades for use when in side discharging
mode. Use the blade bolt and washer for installing the
recycler blades in Step 4.
Warning
A blade is sharp. Contact with sharp blade can
cause serious personal injury.
• Wear gloves or wrap sharp edges of the blade
with a rag.
Before Installation
1. Thoroughly clean mower deck. All debris must be
removed to ensure baffles will fit properly against
mower deck.
2. Repair all bent or damaged areas of mower deck and
replace any missing parts.

7–Gauge Mower Deck
Note: The bolts are threaded into the mower deck. Remove
the nuts first before removing bolts.
1. Remove the nuts holding the front baffle in place
(Fig. 2).
2. Remove the nuts holding the discharge baffle in place
(Fig. 2).
3. Remove the bolts holding the front baffle in place
(Fig. 2).
4. Remove the bolts holding the discharge baffle in place
(Fig. 2).

Procedure
Note: All holes exist in the mower for installing the new
baffles.
Note: Loosely install the baffles to align the baffles with all
existing holes in the mower. Tighten the tapping bolts into
the mower first, before tightening the flange nuts.
1. Install the right baffle into the mower.
Note: The tabs on the baffle for the center chamber need to
be installed to the outside.
2. Secure the right baffle to the mower deck with
2 tapping bolts (3/8 x 1 inch), 1 washer (3/8 inch, only
for Turbo Force mower decks), and 2 flange nuts
(3/8 inch) (Fig. 4).
3. Secure the right baffle to the rear baffle with 1 bolt
(3/8 x 1 inch) and 1 flange nut (3/8 inch) (Fig. 4).
4. Secure the right baffle to the mounting plate with
2 bolts (3/8 x 1 inch) and 2 flange nuts (3/8 inch)
(Fig. 4).
5. Install the left baffle into the mower.
6. Secure the left baffle to the mower deck with 1 tapping
bolt (3/8 x 1 inch) and 1 flange nut (3/8 inch) (Fig. 4).
7. Secure the left baffle to the front flat plate of the mower
with 1 carriage bolt (5/16 x 1 inch) and 1 flange nut
(5/16 inch) (Fig. 4).
8. Secure the left baffle to the left sidewall of the mower
deck with 1 carriage bolt (3/8 x 3/4 inch) and 1 flange
nut (3/8 inch) (Fig. 4).
9. Secure the left baffle to the rear baffle with 1 bolt (3/8 x
1 inch) and 1 flange nut (3/8 inch) (Fig. 4).

Installing the New Blades
lush and dense grass you may need to raise the
height-of-cut setting 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.
Parts needed for this step:
Qty.Part
3Mulching blades
Procedure
Important The sail part of the blade (i.e., the turned up
section) must face the inside of the mower (Fig. 5).
1. Install the new blades to the spindles with washers and
blade bolts that were previously removed (Fig. 5).
2. Tighten the blade bolt to 85–110 ft-lb (115–150 N⋅m).

Mow at proper intervals – Under most normal 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. A dull
blade will tear and shred the grass. 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.

Warning
A blade is sharp. Contact with sharp blade can
cause serious personal injury.
• Wear gloves or wrap sharp edges of the blade
with a rag.
Mulching Tips
Selecting the proper height-of-cut setting to suit
conditions – Remove approximately one inch or no more
than 1/3 of the grass blade when cutting. In exceptionally
