5.2.2 MULCHING SCREEN:
The SM32S model is designed with a screen in the bottom of the rotor frame. The screen retains the
wood material in the rotor chamber until it is small enough to exit through the holes and drop to the
ground under the rotor.
The standard screen features 1-1/2" (38 mm) diameter round screen, for general purpose mulching.
Two optional screens are available: 3/4" (19 mm) diameter round for a finer mulch and 1-1/2" x 7.0" (38
mm x 178 mm ) oblong hole for wet material. See Accessories section for ordering information.
To remove the mulching screen:
1. Ensure the engine is off (ignition
switch is off and the fuel valve is
closed).
2. Carefully tilt the machine back,
so the hoppers are resting on
the ground and the bottom of the
machine is exposed
3. Remove the two mounting nuts
and bolts that hold the screen into
the bottom housing.
4. Remove the screen.
5. Reverse steps to re-install the
screen.
