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.
Why Do I Need An Operator's Manual?
This manual has been created to help you gain the important knowledge of what is needed to
safely operate, maintain, and service your machine. It is divided into sections for convenient ref-
erence of the appropriate section.
You must read and understand the operator’s manual for each piece of Ventrac equipment you
own. Reading the operator’s manual will help you become familiar with each specific piece of
equipment. Understanding the operator’s manual will help you, as well as others, avoid personal
injury and/or damage to the equipment. Keep this manual with the machine at all times. The
manual should remain with the machine even if it is sold. If this manual becomes damaged or
unreadable, it should be replaced immediately. Contact your local Ventrac dealer for a
replacement.
When using a Ventrac attachment, be sure to read and follow the safety and operating instruc-
tions of both the power unit and the attachment being used to ensure the safest operation
possible.
The information in this manual provides the operator with the safest procedures to operate the
machine while getting the maximum use out of the unit. Failure to follow the safety precautions
listed in this manual may result in personal injury and/or damage to the equipment.
