wood products can expose you to wood
dust, a substance known to the State of
California to cause cancer�
Avoid inhaling wood dust or use a dust
mask or other safeguards for personal
protection� For more information go to

WARNING
Wear an approved dust mask or
respirator�
Follow local, state and federal
regulations�
Although the brush mulcher has been carefully
inspected and checked prior to shipment from
manufacturer, it is recommended that the unit be
thoroughly inspected.
Check all bolts for tightness and remove all shipping
tags, bags, skids, and blocking.
Review and understand this manual and operating
unit manual.
Remove any masking materials affixed during
painting. Inspect the tractor and any accessory
equipment to verify that nameplates and all safety
warning, caution signs and decals provided with
the equipment are in place and clearly visible.
Visually inspect the unit before each start up.
Check for loose or missing parts and any damage
that may have occurred during moving or shipping.
Review all tractor pre-start instructions, and be
sure that all recommended steps and procedures
have been followed.
4 OPERATION
4�1 Preparation For Use
4�2 Driveshaft Dimension
A PTO driveshaft is supplied with the machine. To
accompany the variety of 3 point hitch geometry
available today, the driveshaft can be too long for
most machines or too short for others. It is very
important that the driveshaft be free to telescope
but not to bottom out when going through its
working range. If the driveshaft bottoms out, the
bearings on both the machine and tractor PTO
shaft will be overloaded and fail in a short time.
1. To determine the proper length of the driveshaft,
follow this procedure:
a. Clear the area of all bystanders.
b. Attach brush mulcher to tractor (see section
4.5) but do not attach driveshaft.
c. Raise mulcher until the input shaft is level
with tractor PTO shaft.
d. Measure dimension between locking
grooves on tractor PTO shaft and machine
input shaft.
e. Measure the same dimensions on the
compressed driveshaft.
f. If compressed driveshaft dimension
exceeds the machine dimension, driveshaft
will have to be cut.
2. When cutting the driveshaft, follow this
procedure:
a. Subtract machine dimension (A) from
uncut driveshaft dimension (B) or (B-A).
This dimension determines how much too
long the driveshaft is.
b. Add another 1 inch (25 mm) to the
dimension to be sure it doesn’t bottom out,
to determine (C) the cut off dimension.
c. Use a hacksaw to cut dimension (C) from
both ends. Cut both plastic tubes and metal
cores.
d.
Use a file to remove burrs from edges that
were cut.
