Overview
The Weiler B357 Feller Buncher is a compact, purpose-built machine designed for agility, durability, and all-day comfort. Weighing approximately 60,000 lbs, it's ideal for 20–22 inch felling heads in thinning or final fell applications. A forward-positioned, heated and cooled cab with LED work lights ensures exceptional visibility and operator comfort, while the intuitive control system enhances ease of use. The forestry-duty undercarriage features reinforced track guards, debris-shedding steps, and extreme-duty components for maximum durability in rugged conditions. Despite its lightweight frame, the B357 delivers reliable performance with upsized features like a heavy-duty swing drive and Cat® final drives. Designed for low ground impact and easy transport, it also offers excellent serviceability through gull-wing and hinged service doors. Paired with the CP222 hot saw head, it delivers fast cycle times, optimal visibility, and long-lasting performance.
