Machine Description

Design
The RG 25HD STUMP CUTTER is designed for your
maximum benefit per dollar spent. The machine is constructed
for durability and easy maneuvering, for those hard to reach
tree stumps and roots. Its 14" diameter x 3/8" thick cutting
wheel with 12 replaceable carbide-tipped teeth is powerfully
driven by a Kohler 25 horsepower engine. The operator
benefits from a steel cutting wheel guard and full protection
from heavy rubber curtains below the chassis.
Other special features of the RG 25HD STUMP CUTTER
include: self propelled drive via a hydrostatic transmission,
an operator's presence system,
positioning, steel guards surrounding moving parts, and
convenient access for tightening the V - belt.
How it works
The machine removes tree stumps by the repeated gradual
sweeping of a multi-toothed high-speed rotating cutting
wheel. The cutting wheel has teeth on its side, in a strategic
pattern. The rotating cutting wheel takes a sweep from one
side of the stump to the other, each tooth rapidly tearing and
stripping away small pieces of stump. After each sweep of 1
to 2 inches of depth, the cutting wheel is advanced deeper
into the stump, and the procedure is continuously repeated,
under the precise control of the operator, until the stump is
satisfactorily removed.
