Deere Disc Saw Felling

John Deere announces its newest forestry attachment offering with the FR27 disc saw felling head. Now standard on the John Deere 953M and 959M feller-buncher models, and available as an upgrade on the 853M, 859M and 903M feller-bunchers, this felling head attachment has a larger cut capacity compared to previous felling head models. Building upon the success of the FR24B, John Deere has successfully designed the durable FR27 as a solution aimed to increase productivity on the job.

The FR27 is designed to take on a variety of timber applications, from large single stem cutting to mid-sized accumulation, and boasts an all-new design and overall rebranding from previous John Deere felling head models. In addition, this robust, high rotation felling head features excellent cut and accumulation capacity, offering top-of-the-line productivity compared to previous models. The FR27 features an impressive cutting capacity of up to 27.2" and an accumulation capacity of up to 7.5', improving capability in the woods. Building upon the success of the field proven FR24B, the

FR27 features an updated frame and wrist design, which includes a tall horn, long harvesting arms and continuous hose routings that promote easy machine clean-out. The hardened saw housing wear plates are now standard and offer improved saw housing wear resistance.

Additionally, the FR27 offers bolton saw housing for improved serviceability, with three separate saw housing sections with integrated skis getting you back on the job sooner. The incorporated large side chip exhaust chute minimizes build up and plugging, keeping your machine up and running. The side chip exhaust chute also includes a cover that can be added or removed depending on application. Visit johndeere.com.

Tigercat Head Controls

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. The system offers powerful functionality, simplicity and intuitive operator navigation. There are two types of bucking controls available for D7. Prioritybased bucking logic utilizes 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. 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.

D7 is currently available for the Tigercat 534 harvesting head. Visit tigercat.com.
