It is described as a robust, high-performance, two-wheel drive harvesting head.
The 570 harvesting head utilises many of the structural and hydraulic performance benefits of the larger 575, in a package ideally suited to Tigercat H845 series carriers. The wheel arms, pins, bushings, cylinders, feed motors and rotator are shared with the 575 model for proven strength and long life. The design focus has been on optimal strength-to-weight, while also allowing good visibility, component protection and quick service access. The head has a new integrated valve package to improve performance and service access with fewer hoses and connections to improve reliability. Clean electrical routing with common service parts further increases up-time.
Dual-purpose harvesting and processing knives come standard with independent cylinders, allowing crooked or heavily limbed stems to be processed with ease. The knives have replaceable blades and tips. The dual, independent cylinders allow the knives to follow the stem profile, improving control and delimbing quality. Optional hydraulic front knife timing improves picking-up performance in processing applications, while optional harvesting knives with shorter tips enhance harvesting dexterity. Various wheel and motor options are available to tailor performance to application.
The 570 is designed to be most productive in trees of 15 to 50 cm (6 to 20 in) diameter in softwood and hardwood stands. Although best suited to the Tigercat H845 series, the 570 is designed to work with the H822 and H855 series carriers or a 20 to 25 tonne forestry excavator. The 570 and 575 harvesting heads both use the Tigercat D5 Control System which combines a proven hardware and bucking (cross-cutting) control system with a Tigercat-developed head control and user interface. The control system is available in three levels of bucking control and reporting: Tigercat D5 Prio, Tigercat D5 Prio PC and Tigercat D5 Optimization, allowing customers to tailor the system to their needs.
