The Weiler B458 is a leveling machine for steeper terrain and excels in select or clear-cut logging. The B458 provide a leading combination of lift capacity, swing torque, and drawbar. Multi-function performance is achieved through dedicated pumps and optimized circuit configurations. The B458 has an extended track roller frame option that includes two additional bottom rollers for a total of eleven, enhancing overall machine stability in steep terrain. In addition, a standard or heavy counterweight option is available for a diversity of harvesting conditions. Unobstructed ground clearance enables unimpeded travel over stumps, rocks, and other debris.


Excellent multi-function capability through dedicated hydraulic pumps and optimized circuit configurations.  Performance boosted by efficient travel speeds, maxiumum stability, and strong combination of lift capacity, swing torque, and tractive effort.


Elevated, unobstructed carbody with 35” (881 mm) of ground clearance enables unimpeded travel over rocks, stumps, and other debris.  Leveling cylinders do not extend below the bottom surface of the carbody, minimizing potential interference.


Variable gauge, eleven roller extended track frame option, provides maximum stability for steep slopes.  Innovative ease-of-use features, such as the ability to reduce the frequency of foot pedal motions, improves operator efficiency.


New cab maximizes operator experience through increased space, improved visibility, easier access, and options that include a heated and cooled seat, deluxe lights, and cameras.  Machine controls feature an easy to use operator interface.


Forestry-duty cooling package and extensive validation of key common components that includes the engine, swing system, and grease-lubricated Cat® 336 HD HEX undercarriage ensure machine uptime and reduce operating costs.


Counterweight walkway enables machine level access to gull-wing engine enclosure that provides unmatched serviceability of components.  Enclosure provides a flat area to complete preventative maintenance and service.
