FELLER BUNCHERS

 

Caterpillar
Multi-functioning, maneuverability, lift capacity and quick saw recovery are key advantages of the Cat® track feller buncher. The Cat 500 Series can climb steep slopes while the boom, stick and tools function simultaneously, increasing productivity. Zero and full tail swing models, several with leveling systems, are available. The rugged undercarriage travels through wet lowlands or climbs steep, rocky terrain. Ground clearance is 30-35-in. (762-889 mm) depending on the model. Improved hydraulic flow management regulates the distribution of hydraulic oil between functions to increase speed and smoothness. A new hydraulic oil level sensor makes it easy to ensure the tank contains the required amount. Another upgrade improves machine start-up when the engine is cold. The cab also has been updated recently to improve operator comfort and visibility. Wheel feller bunchers are also offered.
