New From Tigercat: D7 Control System

The Tigercat D7 control system combines a solid and field proven hardware and bucking control system with a Tigercat developed head control and user interface, currently available for the Tigercat 534 harvesting head. The system offers powerful functionality, simplicity and intuitive operator navigation.

There are two types of bucking control available for D7. Priority-based bucking logic utilizes a list of operator-entered log specifications sizes to determine how best to process the tree. The 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.

Both Tigercat D7 Priority and Optimization levels offer StanForD Classic, StanForD 2010, and PDF production reporting based on contracts, operators, species, and product groups. The reports provide total quantity and volume, as well as per species and product group quantities and volume. Reports can be viewed on screen, or exported for later analysis. D7 also sends production volume data to RemoteLog, Tigercat’s optional telematics system.

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.

Research Shows Thinning Benefits Bees, Forests

Researchers in Colorado over a 10 year period have determined that forest thinning opens up canopies and benefits key tree pollinators by allowing more flower and shrub species that attract and sustain bee populations. Biologists from Colorado State and Utah State studied 15 thinned and 15 unthinned forest plots and found more species diversity and better overall forest health in the thinned tracts…
