The new stick boom offers a narrow design to help minimize damage to harvested trees.
To help loggers maximize timber quality, John Deere has upgraded its harvester stick boom attachment across all 800MH and 900MH Series tracked harvesters. The new stick boom geometry delivers the same high level of boom envelope performance, but with a narrower design to help operators minimize damage to harvested trees. Avoiding unnecessary damage to harvested trees is always a risk when using mechanised equipment due to the reduction of log values. The narrower boom allows loggers to reduce boom to tree contact, resulting in higher quality logs.
The new boom stick is 122mm (4.8 in) narrower at the attachment end than the existing booms, reducing contact with the harvested tree. This narrower boom uses the standard Waratah supplied dogbone adapter for traditional external hose routing. A new, narrower cradle supplied by Waratah will continue to offer customers with an optional through-the-nose plumbing solution. Source
