There are a variety of harvesting heads on the market targeting the larger end of the log size spectrum. They aren’t all up to making the 120-ft. poles that Beaver Fever Contracting is harvesting, but they all address the need for more power in big wood. Here are some options.

Cat PF-48

 

The PF-48 is a fixed head with a maximum knife opening of 788 mm (31 in.); maximum full coverage delimbing capacity of 480 mm (19 in.) and high torque Poclain feed motors with speeds of 4.3 m/sec. The 4-roller design gives the head more contact with the tree for better feeding and more torque than a two-roller head. The hydraulics and valve body are mounted on the carrier — not out on the head getting slammed into the ground and taking the abuse. Other features add to the head’s robustness: the knife cylinder pin anchors into the frame, dissipating the stress that could cause cracking in the knife cylinder mounting. The thick saw cover reduces the chance of damage from falling limbs.

Ponsse

The Ponsse H8 was built to sustain enough feed power to handle larger trees. With a roller opening to a maximum of 740mm (29 in.), the H8 uses distinctive grip geometry to provide an easier hold for large stems. Lighter than many big wood harvester head options, Ponsse’s largest model weighs just 1,300kg (2,860 lbs.).
The H8 specializes in user-friendly features to make adjustments easier during the job, like better control of feed rollers and blade grip pressure, and feed acceleration and deceleration. With one stationary and four hydraulically movable knives, the H8 has innovations that significantly speed up harvesting, and ensures optimum sawing efficiency.
