Caterpillar offers felling and
bunching heads for tree-
length harvesting by track and
wheel machines that will keep
loggers felling all day long. The
attachments, designed and built
for applications ranging from
plantation thinning to select
harvesting of large diameter
trees, provide reliable, productive
solutions for tree-length felling.
Caterpillar recently introduced
the new D Series Wheel Feller
Buncher. It can be equipped
with any of three Cat saw heads,
the HFW221, HFW222 SC, or the
newest model, the HFW232 High
Capacity Bunching Saw. These saw
heads allow maximum visibility of
the cutting area and utilize high
pressure hydraulics for fast saw
recovery and quick arm speed –
boosting production and improving
tree control.
At the heart of each saw head
is a field-proven saw shaft and
bearing designed for ease of
greasing and durability in high
cycle applications. The upper
and lower bearing chambers are
individually sealed, lubricated
and vented from the bottom up.
Market-leading replaceable,
The Caterpillar 522B tracked feller buncher takes advantage of the flexible nature of the latest Cat heads to make
light work of a steep job
