Forestry Machines and Attachments by Application

Weiler feller bunchers deliver the power and stability you need to get trees cut safely, while Weiler’s new S-series skidder lineup and Peterson’s own TSK help you get logs to the landing regardless of terrain.

No selection of forestry excavators offers you more than Cat’s expanded 500 series. Led by the industry-standard 568FM, the 500 series of forest machines excels in a variety of logging applications from roadbuilder to processor, shovel logger, yoder, and log loader. And once you get to the millyard, trust Caterpillar M-series wheel loaders to get trucks unloaded and back to work in no time.

Peterson also offers Cat land management products including the rugged D3K2 mulcher and the nimble 299D3 XE. And Peterson is a supplier of a full lineup of forestry attachments including Pierce grapples, plus Satco and Logmax processing heads.

Log Loader/Processors

The industry took notice when the Cat 568 was introduced back in 2011. This machine quickly proved itself as a reliable asset in the Western woods, moving logs in tough ground like no other machine can. Today, the 568 is joined by Cat’s 538, 548, and 558 swing machines, which draw their design and features from the 568’s success. From shovel logging to truck loading to processing, you can depend on Cat 500-series forest machines to improve your productivity, reduce your downtime, and raise the bar on performance for your operation.

Wheel Dozers and Loaders

Where Cat’s woodchip dozers leave off, our selection of wheel dozers and loaders pick up. Cat wheel dozers combine the strength and performance of the Cat wheel loader lineup with a large capacity blade/scoop capable of lifting dozens of yards of material at a time and positioning it on the pile.

Cat wheel loaders, including many of the models available for millyard usage, are the optimum solution for loading and transferring chips as well. Large capacity buckets, including high dump models, fill trailers with ease, or load conveyor systems and burners. Whatever the use, there’s a Cat forestry machine for the job!

Machine Rebuilds

Knowing heavy equipment works in some of the toughest conditions on the planet, Caterpillar designed its products with the Built to Be Rebuilt philosophy in mind. This means every component on large machines (dozers, mining shovels, off road trucks, wheel loaders for example) is available for purchase independently, and the machines’ frames are strengthened to withstand the stresses of multiple lifecycles. Given the frame’s integrity at the end of a lifecycle, Peterson technicians disassemble the machine down to this bare frame, then rebuild components like hydraulic pumps and motors, diesel engines, and transmissions/torque converters. The parts are then added back to the machine in a process so high quality Caterpillar recognizes the machine as new from the factory and assigns a new serial number.
