joystick. In doing so, ER transfers
energy back and forth between the
main and the stick boom functions,
reducing the total energy required
and freeing this energy up for other
machine functions or fuel savings.
“Although similar in function,
systems from other manufacturers
do not offer the fuel-efficiency
benefits of ER,” Tigercat stated.
820D track feller buncher
Building on the highly successful
822D/LX830D limited tailswing
platform, Tigercat has introduced
the compact and nimble 820D track
feller buncher.
The 820D shares a redesigned
and enhanced cab with the 822D
and LX830D models. Narrower
front posts and larger side windows
expand sight lines to both the right
and left sides. The skylight has
been replaced by a camera system
providing the operator with a much
wider field of view and eliminating
visibility inhibiting elements like
snow and debris for year round
capability.
The cab interior is quiet
and instrumentation has been
thoughtfully placed to optimize
ergonomics. The electronic control
system interface uses a high-
resolution, 180 mm touch screen
colour display. There are multiple
mounting points for additional
electronic devices.
The engine compartment is
easily accessed via the power-
operated side platform and roof
enclosures. Access to components
and daily service points is excellent
with available ground level fuelling
and easy access to the hydraulic
filters, hydraulic oil fill pump,
swing gearbox remote oil level
tank, cooling system components
and both sides of the engine.
The Tigercat FPT N67 engine
is available in Tier 2 or Tier 4
configurations. The N67 engine
is equipped with a second
generation common rail fuel
injection system, allowing it to
achieve top performance in terms
of load response, maximum torque
and top power with minimum
fuel consumption. For Tier 4 final
regions, the 820D 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.
