ASTEC Drum Chipper

ASTEC Industries Peterson’s 4300 and 6300 series drum chippers are available in double or triple grouser tracked options. Powered by a Caterpillar engine, Peterson drum chippers boast high torque for high volume production. Chip accelerators enable faster load times with more chips in each truck.

The 4300B drum chipper can easily handle material from logs up to 26" (61 cm) in diameter, to brush and small feedstock.

The chipper utilizes a 36" diameter by 40" wide (91 by 102 cm) drum with wear resistant AR450 wear surfaces on the drum pockets and shell.

A sloped feed deck makes feeding the chipper easier. The optional material sizing grate and chip accelerator ensures tight chip packing and fully loaded chip vans. All models come standard with an end-load spout; the 4310B and 6310B are available with an optional top-load spout. The discharge system can either add load density or propel chips significantly farther from the machine for in-woods and clearing operations.

The grate system provides ultra-consistent chip sizing; twigs and small stems are easily fractured through an innovative system. Easy access knives on all drum chipper models have a patented safety latch system which prevents the drum from moving during knife changes. Anvils are made from AR400, for long life and accurate chip sizing.

The 4310B is also available as a Highwalker giving extra ground clearance for landclearing operations. More torque creates superior fuel efficiency. Longer knife life reduces downtime from replacing wear parts frequently and the Adaptive Feed speeds reduce engine load and increase fuel efficiency. Visit astecindustries.com.

Grapple Attachments

Tigercat is steadily growing its line of grapple attachments in an effort to provide end-to-end Tigercat branded solutions that integrate seamlessly with Tigercat loggers, loaders and shovel loggers.

The new butt-n-top and shovel clam grapples are built with durable boxed style jaws fabricated from high strength steel. Replaceable tine tips are made from abrasion resistant steel.

High quality, heavy duty components are used throughout. Cushioned cylinders, and a softstart and stop slew hydraulic circuit prevent structural shock loads and promote extended grapple life while providing ample speed and torque for excellent performance.

Hydraulic hoses are routed on top of the boom and under the connecting pin to best protect the hoses from damage. The BT08 and SC08 grapples are simple to maintain with easy access to daily service points and critical components. A sealed electrical box protects electrical components from the elements.

With an 8 ft2 load capacity area, the BT08 butt-n-top grapple is designed to match up to the 865, 875E and 880E series loggers. The overall design provides exceptional control of tree-length timber. The jaw profile rolls the logs into the load area to maximize load size and minimize cycle times.

The new Tigercat SC08 shovel clam grapple is designed for the LS855E and LSX870D shovel loggers. Also with an 8 ft2 load capacity, the shovel clam grapple provides an alternative to dangle style log and bunching grapples. The SC08 can enhance shovel logger functionality and productivity by increasing control of the trees and the speed at which the operator can gather and manipulate the bunches. Visit tigercat.com.

Designed to achieve exceptional stability, the 180 can achieve high line pull without the use of guylines in most operating conditions. The undercarriage has a reinforced pedestal and carbody with an extended blade for added stability. Blade mounts are tied directly into the carbody for added strength. The machine can be quickly moved to the next setup by simply lifting the blade. In operating situations where additional stability is required, such as with extremely long yarding distances or low deflection conditions, a simple static guyline can be quickly set up. The machine still retains the ability to swing with this guyline attached.

The winches are driven with efficient dedicated closed loop hydraulic circuits for smooth operations and infinitely variable speed control. The closed loop circuits provide energy when lowering the load for increased efficiency. Intuitive joystick controls, along with many programmable features reduce, operator training time and increase production. Visit tigercat.com.
