POWERFUL PERFORMANCE.
Powerful combination of lift capacity, swing torque, and tractive effort provides for maximum machine performance, increasing overall machine efficiency and operator experience in high production felling applications.
Track Feller Bunchers
The Weiler B757 track feller bunchers provide industry leading lift capacity throughout full reach, a key benefit in large timber. A robust undercarriage utilizes proven components, customized for demanding forestry conditions while maintaining industry leading ground clearance. Both reduced tail swing and full tail swing machines are available as tilting or non-tilting to meet a variety of application requirements.
UNOBSTRUCTED GROUND CLEARANCE.
High, unobstructed carbody enables un-impeded travel over rocks, stumps, and other debris with 35” (889 mm) of ground clearance. Approximately 90° carbody to roller frame interface allows maximum clearance across the width of the carbody.
PURPOSE BUILT LOWER FRAME.
Variable gauge roller frames provide flexibility in machine width, for over-the-side stability or transport. Optional star rollers, available for certain ground conditions, help shed debris and improve track retention.
MAXIMUM FUEL CAPACITY.
Large fuel tank with 312 gal (1181 L) of capacity is designed to enable two complete shifts of operation, which increases machine uptime and reduces owning and operating costs through less time spent fueling and reduced travel.
PROVEN RELIABILITY AND DURABILITY.
Extensive validation of common key components that includes the engine, hydraulic pumps, swing drive, and grease-lubricated Cat® 336 HD HEX undercarriage ensure machine uptime and reduce overall operating costs.
EXCELLENT SERVICEABILITY.
Gull-wing engine enclosures provide unmatched serviceability of components and enables “walk-through” engine access from the cab side of the machine. Enclosures provide a flat area to complete preventative maintenance and service.
