Tigercat releases 570 harvesting head 

Tigercat continues to expand its range of harvesting heads with the new 570, a robust, high-performance, two-wheel drive harvesting head.

The new Tigercat 570 harvesting head offers excellent productivity and reliability, utilizing 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 chassis is designed for optimum strength-to-weight with focus on visibility, component protection and quick service access. A new integrated valve package enhances performance and service access with fewer hoses and connections to improve reliability. Clean electrical routing with common service parts further increases up-time.

Flexible configurations

Dual-purpose harvesting and processing knives — with replaceable blades and tips — come standard with independent cylinders as the ultimate solution for crooked or heavily limbed stems. The dual, independent cylinders allow the knives to follow the stem profile, improving control and delimbing quality. The 570 is flexible and configurable. Optional hydraulic front knife timing improves picking 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 most productive working with trees 15-50 cm (6-20 in) 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 20-25 tonne forestry excavator.

Tigercat D5 control system

The 570 and 575 harvesting heads both use the Tigercat D5 Control System which combines a solid and field proven hardware and bucking control system with a Tigercat-developed head control and user interface that offers simplicity and intuitive operator navigation. The Tigercat D5 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.
