Where to buy

The most popular heavy-duty, all-round harvester/processor head, the Waratah HTH622B is engineered to handle a wide range of applications — in the toughest conditions, the HTH622B is highly efficient in either stump-to-stump harvesting or roadside processing. Its find-end feature, topping saw, and TimberRite measuring system work together for extraordinarily accurate, intelligent processing results.

Features include a stronger body design with strengthened hanging bracket and double shear pins. Plus we’ve redesigned the hydraulic system and provided additional clearance for the saw unit and higher visibility throughout the head. The HTH622B offers a fixed knife in the saw unit, along with a lockable front knife for debarking/delimbing.

With a synchronized three-wheel feed system to provide superior traction and speed while processing, the HTH622B is optimal in 56-centimeter (22-inch) diameter wood.
