Tigercat 724G drive-to-tree feller buncher working in Virgina
eucalyptus pulpwood on account of
the fast shear cycles and extremely
efficient carrier hydraulics. The
2000 shear accumulates large
parallel bunches, improving
skidder productivity.
In addition, the shear is a lower-
cost, lower-maintenance alternative
to a disc saw felling head. In
rocky or abrasive soil types, the
maintenance and wear benefits are
even more pronounced. The shear-
equipped feller buncher also burns
less fuel compared with a disc saw.
The 855D can also be mated to
the Tigercat 5185 directional felling
saw for an extremely fuel efficient
machine to fell and shovel large,
high value timber.
The L855D features Tigercat’s
patented forest-duty leveling
undercarriage, providing
exceptional stability on steep
slopes. It uses two massive
hydraulic cylinders and heavy
steel sections for a solution that is
simple, robust and reliable.
Similar to the 820D, the 855D
and L855D are powered by the
Tigercat FPT N67. For Tier 4 final
regions, the N67 engine on the
855D/L855D delivers 210 kW (282
hp) at 2,200 rpm and for Tier 2
regions it is rated at 205 kW (275
hp) at 2,100 rpm.
Drive-to-tree feller bunchers
Tigercat builds three models of
drive-to-tree feller buncher models
for the full range of thinning and
final felling duties. The 720G and
724G are designed for thinning and
clear fell applic
