OPERATING INSTRUCTIONS
Mulching Trees S
maller than 6”
1. First, you must decide if you can mulch the
standing tree as one piece, based on the trunk
diameter. If the tree is
a softwood of 6” diameter
or less (5” diameter or less for hardwood), use
the procedure below.
2. To properly mulch an entire tree, make sure the
disc is spinning at maximum RPM. This may take
up to 45 seconds if starting from a dead stop.
With the mulcher tipped back at a 20 to 45-
degree angle, raise the front of the mulcher about
3 feet to 6 feet off the ground. Position the
mulcher so the tree is in the disc ingestion zone
(between the 12 o’clock and 2 o’clock position)
Then slowly move into the tree and slowly raise
the loader arms to ingest the top portion.
Always keep the attachment
tilted back so that you are not exposed to
flying debris
3. Once the tree top is cut off and the disc speed
has recovered to full RPM, lower the attachment
slowly over the remaining tree trunk to mulch it.
If you lower the attachment too quickly you may
stall the disc. You may need to drive forward and
backward a small amount to ensure the teeth on
the bottom of the disc are engaging the tree trunk.
4. If the tree falls to the ground without being
ingested directly into the top of the disc, you can
still process the tree in one piece. To do this,
position yourself parallel to the tree trunk and
facing the bottom end. Lower the front of the
mulcher deck to the ground and feed the lower
end into the ingestion zone of the disc.
NOTE:
When shutting down the attachment, the
inertia of the disc will cause it to continue spinning for
several minutes after the hydraulic drive is
disengaged. To stop the disc faster, grind a stump
with the hydraulic drive disengaged.
Before leaving the operators
position, disengage hydraulic drive, lower the
attachment to rest flat on the ground, stop engine,
set park brake, and wait for all motion to
stop. Even after disengaging the hydraulic drive,
the disc will continue to spin for several
minutes. Do not leave the operator's position or
allow other people to approach the attachment
until the disc has stopped.
