1. INTRODUCTION
Congratulations on your choice of a Baumalight
3-Point Stump Grinder to complement your stump
grinding operation. This equipment has been
designed and manufactured to meet the needs
of a discriminating buyer for efcient grinding of
stumps.
Model 3P24 has 34 teeth on a 24 in. cutter and
models 3P34 and 3P40 have 54 teeth on a 34
in. cutter. This means less cutting for each tooth
resulting in longer tooth life and smoother cutting
for less wear on the tractor. Heavy tooth population
makes ner mulch and smoother operation.
The cutting wheel is powered by the PTO on your
tractor with the swing and lift cylinders activated
by the standard remote hydraulic connectors on
the tractor.
Grease zerks and replaceable brass bushings are
provided at major pivot points for extended service
life.
The debris shields is standard equipment on all
stump grinders. It is recommended that the stump
grinder never be operated without one.
Safe, efcient and trouble free operation of your
Stump Grinder requires that you and anyone
else who will be operating or maintaining the
Stump Grinder, read and understand the Safety,
Operation, Maintenance and Troubleshooting
information contained within the Operator’s
Manual.
This manual covers the Baumalight 3-Point Stump
Grinder, models 3P24, 3P34 and 3P40. Use the
Table of Contents as a guide to locate required
information.
Keep this manual handy for frequent reference
and to pass on to new operators or owners. Call
your Baumalight dealer, distributor or the factory
if you need assistance, information or additional
copies of the manuals.
1.1 Overview
When this machine is worn out and no longer in
use, it should be returned to the retailer or other
party for recycling.
OPERATOR ORIENTATION - The directions left,
right, front and rear, as mentioned throughout this
manual, are as seen from the tractor driver’s seat
and facing in the direction of travel.
1.2 Intended Use And Foreseeable
Misuse
The stump grinding tool is designed to be used
by experienced operators, trained in the safe
operation of a tractor and trained in the hazards
related to using the stump grinder and the safe use
of the grinder for the intended purpose. Operators

within the stump size limits shown in the catalog
and in the implement specications in the manual.
Care is required to ensure that the stump grinding
tool will not come across metallic objects, stones
or other materials harder than a typical stump
while grinding.
Stump grinding tools are not designed for use
in hazardous atmospheres where there is a risk
of re or explosion due to ammable gases or
vapors. Use in hazardous, explosive atmospheres
is prohibited.
Serious injury or death of the operator or

4.3 Driveshaft Dimension
To accompany the variety of 3 point hitch geometry
available today, the driveshaft can be too long for
some 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.
To determine the proper length of the driveshaft,
follow this procedure:
1. Attach stump grinder to tractor but do not
attach driveshaft.
2. Raise grinder until the input shaft is level with
tractor PTO shaft.
3. Measure dimension (A) between locking
grooves on tractor PTO shaft and grinder input
shaft.
4. Measure same dimension (B) on compressed
driveshaft.
5. If compressed driveshaft dimension (B)
exceeds the machine dimension (A), driveshaft
must be cut.
When cutting driveshaft, follow this procedure:
1. Subtract machine dimension (A) from uncut
driveshaft dimension (B). This dimension
determines how much too long the driveshaft
is.
2. Add 1 in. (25 mm) to the dimension to be sure
it doesn’t bottom out, to determine cut off
dimension (C).
3. Use a hacksaw to cut dimension (C) from both
ends. Cut both plastic tubes and metal cores.
4. Use a le to remove burrs from cut edges.
5. Assemble shaft.
6. Make sure shaft can telescope freely. If it does
not, separate and inspect for burrs or cuttings
on shaft ends. Be sure it telescopes freely
before installing.

^ WARNING
Wear an approved respirator (N95 Type
as a minimum).
Follow local, state and federal
regulations.
The health effects from exposure to
wood dust are due to chemicals in the
wood or chemical substances in the
wood created by bacteria, fungi, or
moulds.
Although the Stump Grinder 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. Check swing
frame to ensure that it is free from obstruction and
can operate smoothly without binding.
Remove any masking materials afxed 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.
Verify the three linch pins are securely fastened.
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 ensure
that all recommended steps and procedures have
been followed. Never bar over the rotor, This could
cause damage and result in personal injury or
equipment damage.
NOTE: Always keep the weight of the machine in
mind. Never position body in line of impact.
