New 8B High-Flow Chipper Attachment Delivers Optimal Grinding Performance

WEST FARGO, N.D. — November 2006

For optimal performance when grinding through branches, trees and limbs, customers can turn to the new 8B high-flow chipper attachment from Bobcat Company, a business of Ingersoll Rand, a diversified industrial firm.

The Bobcat® 8B high-flow chipper attachment reduces branch volume 10-to-1, thus limiting trips to the dumpsite and improving wood decomposition. The high-flow chipper also has several new features, including a variable gpm setting, a reset override system and a smart valve and pressure valve to maximize chipper performance.

Bobcat representatives say the new 8B high-flow chipper attachment will be ideal for contractors because unlike pull-type chippers, it can be easily placed in backyards and other remote areas due to the size, agility and maneuverability of a Bobcat loader or utility work machine.

The attachment is approved for use on Bobcat machines with high-flow hydraulic systems. This includes Bobcat skid-steer loaders (models S160H through S300H), compact track loaders (models T180H through T300H) and the Toolcat™ 5600H utility work machine.

The variable gpm setting enables the chipper attachment to operate within two different gpm flow ranges: 26 – 31 gpm and 32 – 37 gpm. This improves chipping efficiency based on the Bobcat machine’s hydraulic flow capacity.
The smart valve feature monitors the chipper disc speed and limits plugging of the chipper head. When the chipper disc speed reaches a threshold level, the smart valve slows the feed roller until the chipper disc has recovered. Once the disc reaches maximum speed, the feed roller will resume. An in-line pressure valve controls the feed roller’s auto-reverse/auto-forward feature. If the system reaches the maximum psi level, the feed roller goes in auto-reverse and -forward until an optimal pressure level is maintained.

In the event the chipper safety bar is tripped, the reset override system allows the operator to reset the chipper without having to restart the entire system.

The 8B high-flow chipper utilizes the Bobcat Remote Attachment Control (RAC) system, which enables the operator to start or stop the loader engine and chipper attachment while standing beside the attachment.
