Soil Moisture Chart
This chart is to be used as a guideline for determining soil moisture. Core processing in conditions that fall into the shaded area
of the chart may give less than desirable results.

Inspecting and Cleaning the
Brush/Chopper Housing
Service Interval: Every 4 hours —Clean more often in high
soil moisture conditions.
The brush/chopper housings will buildup with mud more
rapidly when used in grass longer than 25 mm (1 inch) height
of cut, clay and loam soil, or in early morning dew. If the
brush housing is not cleaned, premature wear to the brush
will occur. With proper maintenance the brush should last
approximately 100 hours.
To clean the housings, do the following:
1. Raise the processor onto the transport wheels.
2. Loosen and remove the rear cover mounting bolts.
Pivot the cover forward.
3. Using the scraper, located at the front of the machine,
thoroughly clean the housing of mud.
4. Pivot the cover down and secure with the mounting
bolts.
Inspecting and Cleaning the
Machine after Operation
1. When operation has been completed, use the washout
ports
(Figure
36) or spray the chopper area.

2. Turn the key in the ignition switch to the O
and increase speed until the chopper rotator is engaged.
3. Stand to 1 side at rear of machine and spray water into
spinning chopper until clean.
4. After cleaning, inspect the machine for possible
damage to mechanical components.
Note: This assures that the machine is going to perform
satisfactorily during next operation.
