Note:

Rotate the by-pass valves a maximum of 2 turns

so the valve does not come out of the body causing
fluid to run out.

Important:

Do not start or operate the machine

with the by-pass valves open. Damage to system
may occur.

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 baffle, loosen the nut (Figure 15).

4.

Adjust the baffle and nut in the slot to the desired
discharge flow and tighten the nut.

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 16). 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.
