1. After adjusting height-of-cut, check the anti-scalp
rollers so that there is a minimum of 3/8 inch (10
mm) clearance above the ground (Figure 13).
2. If adjustment is needed, remove the bolt, washers
and nut (Figure 13).
3. Select a hole position so the anti-scalp rollers are
a minimum of 3/8 inch (10 mm) off the ground
(Figure 13).
4. Install the bolt and nut (Figure 13).

5. In certain mowing conditions and terrain, a
mismatch of cutting height may be seen. Adjusting
the outside anti-scalp rollers to the minimum setting
of 3/8 inch (10 mm) will help prevent the mower
deck cutting too low on the outside and minimize
the mismatch.

Adjusting the Flow Baffle

The mower discharge flow can be adjusted for different
types of mowing conditions. Position the cam lock and
baffle to give the best quality of cut.
1. Disengage the PTO, move the motion control
levers to the neutral locked position and set the
parking brake.
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. To adjust the cam lock, swing the lever up to loosen
the cam lock (Figure 14).
4. Adjust the baffle and cam lock in the slot to the
desired discharge flow.

too tight, loosen the lever and then rotate the cam
lock. Adjust the cam lock until the desired locking
pressure is achieved.

Positioning the Flow Baffle

The following figures are only recommendations for
use. Adjustments will vary by grass type, moisture
content, and height of grass.
Note: If the engine power draws down and the mower
ground speed is the same, open up the baffle.
Position A
This is the full rear position (see Figure 15). The
suggested use for this position is a follows.
• Use for short, light grass mowing conditions.
• Use in dry conditions.
• For smaller grass clippings.
• Propels grass clippings farther away from the
mower.
