TIGERCAT has unveiled a new harvester head control system.

D7 combines a solid and field proven hardware and bucking control system with a Tigercat developed head control and user interface. The system offers powerful functionality, simplicity and intuitive operator navigation, the manufacturer says.

There are two types of bucking control available for D7.

Priority-based bucking logic utilises a list of operator-entered log specifications sizes to determine how best to process the tree.

D7 Optimization level uses a value-based logic. Using multiple layers of matrices correlating price, demand, and production limits to each log size under each tree species, the control system optimizes each processed tree to achieve the best value.

These matrices are usually programmed by the timber buyer.

D7 can be equipped with a GPS receiver and the GeoInfo software. This provides an active navigation application using the machine's current position on a georeferenced map.

Work site maps can be viewed on the in-cab display screen, allowing the operator to easily view the site layout, track the movement of the machine, and view production information. Restricted areas can be marked with boundary alarms.

D7 is currently available for the Tigercat 534 harvesting head.
