Forestry Machines and Attachments by Application
No selection of forestry excavators offers you more than Caterpillar’s expanded 500 series. Led by the industry-standard 568FM, 500 series of forest machines excel in a variety of logging applications from roadbuilder to processor, shovel logger, yoder, and log loader. And once you get to the millyard, trust Cat M-series wheel loaders to get your trucks unloaded and back to work in no time.
Weiler feller bunchers deliver the power and stability you need to cut trees safely, while Weiler’s new S-series skidder lineup helps you get logs to the landing regardless of terrain.

Forest Machines
Cat Log Loaders and Road Builders
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 528, 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.
