Revamped 568 Harvesting Head

568 harvesting head
Designed for track carriers, the TCi 568 is a robust, high-capacity harvesting head optimized for roadside processing in the 15-55 cm (6-22 in) diameter range. It has the feed speed of a 22-inch head with the feed power of a 23-inch head. Recent design enhancements have boosted performance, increased the strength and durability, and elevated the overall harvesting and processing experience.

The TCi D7 control system comes in either Priority or Optimized bucking control, and both use wireless communication between the head and the machine cab. Cab hardware and wiring have been simplified to use a single module that has constant power for quicker startups and faster processor speed to improve performance and consistency.

The 568 now uses a full-time four-wheel drive system which reduces wheel spin, improves braking performance, and achieves greater feed power than other heads in its class. Balanced frame motors and an optional mechanical frame drive locker improve alignment when feeding multiple stems. Three independent valve sections - one for each arm motor and one for the two frame motors in series improve feeding efficiency. Improved tree centering provides better contact with the length measuring wheel.

The measuring wheel arm cylinder pin and bushing arrangement has been improved, providing better reliability and serviceability. And according to Product Manager Duane Barlow, “We added additional internal guarding and a deflector guard on the measuring wheel arm to help reduce debris accumulation around the measuring wheel.”

The main chassis profile has been refined and strengthened for increased durability and longevity. The main saw box design provides improved chip exhaust, easy cleaning and better protection of the find end sensor. The top saw box cover design makes it easier to service the saw motor. Top knife enhancements include an additional grease fitting, a keyed thrust washer to prevent retaining bolts from loosening, and an upgraded spring unit.
