Product Description
LC150 Stump Grinder
The Ventrac LC150 stump grinder is designed to operate with the Ventrac Series 3000 power
unit. It is a great tool for removing stumps up to 10-12 inches (25.4-30.5 cm) in diameter as well
as remove above ground roots which may damage mowing equipment. It is equipped with a
multi-function arm that is controlled by the auxiliary lever of the power unit hydraulics. This arm
can be used to achieve a common grinding depth of a stump that is repeatable by using the
depth indicator gauge. It also can be used as a blade to level the area where the stump was
ground out. The arm serves as a stand when the stump cutter is removed from the power unit,
holding the hitch arms at the correct height for easy hookup.

SAFETY
B-7
LC150 Safety Procedures
•Set up power unit and stump grinder so that particles are directed away from buildings or other objects
of value.
•During the grinding process, objects can be propelled from the stump grinder causing injury or damage
to people, animals, buildings, vehicles, or other objects of value. Block access to the area prior to
grinding stumps. Use plywood or equivalent shielding to protect nearby building or objects. If access to
the area cannot be prevented, use plywood or equivalent shielding to protect pedestrian areas.
•Stop grinding immediately if the cutter head strikes a rock or other solid object. Damage to the cutting
teeth or the cutter head may occur.
•Do not operate with any of the cutting teeth missing. This causes the cutter head to become
unbalanced and may cause damage to the stump grinder.

OPERATION
C-1
Daily Inspection
1 Park machine on a level surface, with the
engine shut off and all fluids cold.
2 Perform a visual inspection of both the power
unit and the stump grinder. Look for loose or
missing hardware, damaged components, or
signs of wear. Inspect hydraulic hoses, hydraulic fittings, and fuel lines to ensure tight, leak free
connections. Inspect drive belts. Belts should be in good condition.
3 Refer to the power unit operator’s manual. Check the power unit’s engine oil, hydraulic oil, cooling
system, tire pressure, and fuel level. Add fluid or service as required.
4 Inspect the cutting teeth for wear and service as required.
5 Test the power unit’s operator safety interlock system*.
Attaching
1. Drive the power unit slowly forward into the hitch arms on the stump grinder. Align the hitch arms to
complete the engagement.
2. Once completely engaged, close the front hitch latch.*
3. Set parking brake, stop engine, and remove the key.*
4. Install the PTO drive belt onto the power unit. It is easier if the belt
is first removed from the pulley on the gearbox and then installed
onto the bottom groove of the double pulley on the power unit.
Once the belt is installed on the power unit then install it back onto
the bottom pulley of the gearbox. It is also helpful to have the
tension idler rotated so it is centered in the belt. (See Figure 1)
5. Rotate the tension idler pulley over the belt to the left as viewed
from the seat (See Figure 2). Hook the torsion spring inside the
tab that is welded to the left hitch arm (See Figure 3). Do not hold
the torsion spring at the end as this is the area that is held by the
tab. Grasp the spring approximately 1-1/2" from the end to
prevent pinching.
6. Wipe hose ends clean and connect to quick couplers. If equipped,
connect the hoses and quick couplers so the red indicators are
paired together and the yellow indicators are paired together.
Detaching
1. Park the power unit on a level surface and set the parking brake.*
2. Lower the stump grinder to the ground.
3. Lower the multi function arm to the ground. (note detaching point
on decal)
4. Shut off engine and remove key.*
5. Disconnect hydraulic couplers.*
6. Slowly release idler torsion spring and move idler pulley in
between belts. (See Figure 1) Remove belt from power unit drive
pulley.
7. Disengage the hitch latch. (LT3000 - Rotate the locking lever
down and move the hitch lever to the right. See Figure 2.)
8. Restart the power unit and slowly back away from the stump
grinder.

OPERATION
C-2
Operating Techniques and Tips
If a common grinding depth is desired, grind the first stump to the desired depth, then lower the multi
function arm until it contacts the ground with the cutter wheel touching the already ground stump. Note
what line the depth indicator gauge is on, and then move to the next stump. The multi function arm can
be left at the selected level from the first stump while grinding the second stump. When the second
stump is ground down to the correct depth, the arm will prevent further cutting. The depth indicator de-
cal is for reference only and does not indicate actual depth below ground level that the stump is being
ground at.
After the stump has been removed, raise the stump cutter to its highest position and lower the multi
function arm until it contacts the ground. This will allow you to push the debris back into the hole that
remains from grinding the stump out.
Grinding
Before grinding, cut stump as low to the ground as possible with a chain saw. The maximum recom-
mended height is 3” above ground level. Position the grinder above the closest edge of the stump and
lower slowly until it begins to cut. Turn the steering wheel left and right to sweep the cutter head across
the stump. After each pass, lower the grinder a little more and repeat the process.
After removing several inches on larger stumps, move forward and repeat the process as required.
Also on large stumps, it is advisable to approach from several different angles.
Follow this procedure until the stump is cut to desired depth below the ground surface.
If the grinder is lowered too much at one time it will not allow the power unit to be steered. Lift the
grinder slightly to continue side-to-side grinding.
There are variables in stumps. Hardwoods cut much slower than softwoods. Partially decayed stumps
may cut easy in some spots, but still have some hard spots or tough roots. Experience will help the pro-
cess be more efficient.
During the grinding process, objects can be propelled from the stump
grinder causing injury or damage to people, animals, buildings, vehi-
cles, or other objects of value. Block access to the area prior to grinding
stumps. Use plywood or equivalent shielding to protect nearby building
or objects. If access to the area cannot be prevented, use plywood or
equivalent shielding to protect pedestrian areas.

MAINTENANCE & SERVICE
D-1
Cleaning & General Maintenance
•For best results, and to maintain the finish of the LC150, clean or wash the stump grinder after each
use to remove wood shavings, dirt, and other debris.
Service Schedule
Daily
•Check for loose bolts or hardware and tighten as required.
•Check cutting head for loose, dull, or bent cutters. Repair or replace as needed.
50 hours
• Grease the two bearings on cutter head shaft. Do not over grease, usually one pump is sufficient.
• Check gearbox oil level. To check remove the allen head plug at the front of the gearbox. Oil level
should be at the bottom of the plug hole. If necessary, add 80-90 weight gear oil until it reaches this
point.
Maintenance
Gearbox Oil
•Initial change at 50 hrs, then every 500 hrs or annually.
•Refill until gearbox is 1/2 full.
Cutter Head
•Tighten bolts to 35 ft lbs. (47.5 Nm) after 30 minutes of running time after initial start up.
Always set the parking brake, shut off power unit
engine, remove the ignition key, and ensure all
moving parts have come to a complete stop be-
fore inspecting components, or attempting any
repair or adjustment.
Attention
If any component requires replacement, use only
original Ventrac replacement parts.

Cutter Replacement
•The cutter head is equipped with (4) right, (4) left, and (4) straight cutters. It is important to always
replace the cutters in the original positions. It is recommended that the cutters are replaced one at a
time to ensure they are installed in the correct positions.
•Loosen the (4) bolts that hold the cutter in the cutter head. The bolts do not need to be removed, only
loosened. Using locking pliers or some other gripping device, pull the cutter out of the cutter head. On
old cutters that are going to be discarded, it is permissible to use a steel hammer to tap the cutters out.
However if the cutters are to be reused, it is not recommended due to the potential of damage to the
carbide tip on the cutter. Use only a rubber mallet or soft faced hammer on cutters that are to be
reused.
•Insert a 3/8” bolt or clevis pin in the provided gauge hole in the cutter head, which serves as a stop
when positioning a new cutter into the proper depth. Slide the new cutter into the cutter head until it
bottoms out on the bolt or pin in the gauge hole. If necessary, use a rubber mallet or soft faced
hammer to tap the cutter in, or use a block of wood to protect the carbide tip and use a steel hammer.
Once the cutter is installed, tighten the (4) clamping bolts to 35 ft-lb (47.5 Nm). Remove the bolt or pin
that was used as a gauge.
D-2
MAINTENANCE & SERVICE
After replacing the cutter teeth, re-torque the cutter bolts
to 35 ft-lb (47.5 Nm) after 30 minutes of cutting time.
