Long Boom Technology
Hydrostatic Drive
Boom Pivot Assembly
Expandable Track
Knuckled boom allows maximum
swing above and below grade to
access hard-to-reach areas while
maintaining full boom arc swing
regardless of cutting depth.
Hydrostatic primary drive with belt
final drive provides efficient (90%)
power transfer between drive and
cutting system with minimal
moving components.
Heavy-duty boom pivot significantly
reduces wear in critical area of the
stump grinder to provide years of
trouble-free service and allows for
greater boom arm swing radius.
Nachi Rubber Track Undercarriage
with 4.4 PSI ground pressure is
72" long x 9" wide, turf-friendly
and hydraulically expandable from
35" wide to 47" wide.
