Text 1. A FELLER-BUNCHER (SKIDDER)
In April 1992 “Tigercat” unveiled its 726 feller-buncher prototype at a log-
ging expo in Tifton, Georgia. The 726, plus six more models and four felling
heads (equipped with either a saw or shear and a gathering pocket) have resulted
in 200 employees working in four plants. Today the corporation holds nine
plants totalling 770000 square feet and 750 employees. In recent years sales in-
creased and net income levels were maintained, investment in research and de-
velopment continued.
“Tigercat” now has almost 50 dealer locations in the USA and 30 locations in
Canada. Its products are not over-engineered, just properly designed and pur-
pose-built. What loggers want is rugged, reliable, durable, and easily maintained
equipment. But since loggers are faced with adverse operating conditions and
because forestry soil guidelines encourage loggers to use low ground pressure
equipment and make fewer disruptive trips, “Tigercat” builds in extra strength,
power and capacity.
Cooper’s 630 exemplifies “Tigercat’s” innovations in design matters large
and small. Its the world’s first serial production hydrostatic skidder. Essentially,
the hydrostatic drive permits the engine to run at a constant speed, and operator
to start, stop and accelerate with just two foot pedals, eliminating a thousand or
more gear changes a day. They rotated the 726 engine 180 degrees. Creating a
cleaner engine environment and radiator meant better cooling, which meant re-
duced maintenance. Rotating the engine also permitted mounting the numerous
and heavy hydraulic pumps, immediately inside the engine access door. Opera-
tors can change oil in the “Tigercat” in a third of the time they could in the other
machines. Also, a rearward shift of the center of gravity allowed the 720 and
726 feller-bunchers greater lifting capacity at the business end.
“Tigercat’s” cabs are strong, with no plastic and no on-board computers. All of
them are air-conditioned and sport an AM/FM stereo cassette and an ergonomic
seat for operator comfort.
Sloping the windshield in at the bottom, which is surmounted by a heavy
frame, reduces the need for windshield wipers, which are easily wrecked by tree
branches. The 860’s electro-hydraulic operated engine enclosure doors open to
form a large work platform. Regardless of listing on uneven ground, operators
can check the engine without jumping off into deep snow. All “Tigercat” ma-
