Timberjack adds two feller bunchers
TimberJack has introduced the 608L leveling and the 608S non-leveling feller bunchers to their 608 line. The 608L is the first leveling feller buncher, using a patented leveling system called ShiftTilt. This patented 4-way leveling system shifts the center of gravity ahead as the cab is tilted forward. The upper can tilt 27º forward (51% slope), 10º rear (18% slope), and 20º (36% slope) to each side, for working at maximum reach and lift capacity in all directions. The leveling system also allows 360º continuous rotation, so the operator doesn’t have to be concerned about limit stops. The innovative leveling system moves the cab ahead as it tilts forward, allowing the operator better visibility. The 608L is powered by a 230 hp Cummins 6CTA8.3 diesel engine.

It has a 30” ground clearance and an open center carbody to reduce build-upon of debris, snow and ice. It’s equipped with an 18” Timberjack S547 disc sawhead with a 22” severance capacity for handling large butt flares. Its compact size, long reach and near-zero tailswing make it a great choice for thinning. And its 23’3” boom reach gives a wide work radius and reduces machine travel. The 608L is low impact, with a ground pressure of only 7.2 psi on the optional 28” single grouser track, and weighs in at 59,159 lbs. The 608S is a heavier and more powerful version of the 608B. It has a 205 hp Cummins 6CTA8.3 diesel engine but the 230 hp 6CTA8.3 is optional. Like the 608L, it’s equipped with an 18” Timberjack S547 disc sawhead.

The boom has a reach of 25’8” allowing it to work in most 5th row thinnings without travel off the takeout row. It has continuous 360º rotation and features SPEED SENSE, a hydraulic pump control system that matches hydraulic demand to available engine power. Timberjack’s harvesting heads — the FG18 & FG22 — work like giant, flexible hands. With 220º wrist rotation they can be positioned anywhere you want, for faster cutting and bunching without moving the feller buncher. Larger, right sized bunches reduce the number of bunches per cut block, all positioned for fast pick-up by a grapple skidder. The 110º rotation to each side is accomplished by a unique twin cylinder gear drive mechanism, offering lower maintenance than other high rotation wrist systems that use hydraulic motors and gear boxes.

The wide throat opening, large accumulation area and high rotation capability make it easier to cut and gather up to eight small stems before bunching. High rotation enables bunching at full boom reach on both sides of the machine, so each bunch is accumulated and stacked without moving the machine. Both models feature field proven disc saw blade and saw teeth. The FG18 felling head weighs in at 5,905 lbs., has a cutting capacity of 21’5”, a throat opening of 27.35” and an accumulation capacity of 4.53 sq. ft. The FG22 however is 6,575 lbs., with a cutting capacity of 23.35 inches, has a throat opening of 38.75”, with an accumulation capacity of 5.0 sq. ft.
