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 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.

Trucks for Forestry
From building logging roads to hauling timber to the mill, transporting heavy equipment from site to site, or simply hauling processed materials to end users, the forestry industry relies on commercial trucks to deliver the products needed for the world’s markets. International’s truck lineup offers a range of vehicles fitted to the needs of the forestry industry. From the rugged HX and HV to the fuel efficient LT, customers know they can count on an International truck to get the job done.

Dump Trucks
Putting in rock on a new forest road? The International HX is up to the task. With the industry’s strongest frame rail, engine and suspension from leading brands, the HX is ready for any challenge.
Heavy Haul
With an available 20k front axle and 20k steerable or non-steerable lift axle, the HX is ready for extreme weight on road, and rough forest tracks off-road. Plus, it’s designed for maximum comfort that cushions out all the bumps.
Log Trucks
No mention of the International HX would be complete without a summary of its many capabilities as a log truck. This capable truck is built for the challenges, heavy loads, and unforgiving terrain of the Western woods!
Service Trucks
The same service trucks we use come with the choice of International or Cummins engines and available four-wheel drive. Purchase the whole package or just the chassis from your local Peterson Trucks dealership.
Attachments
Processors
Processing heads cut trees to length for easier transport to the sawmill while removing excess bark and branches from the log. They can also fell trees, and in some cases (typically the category of head known as a grapple processor) can be used to stack logs or load trucks. Processing heads are available in fixed or dangle varieties. Dangle processors swing freely from the stick of the forestry machine while fixed heads are manually tilted for easier control. For smaller logs, and depending on the model of processor, more than one tree can be delimbed at a time.
Mulchers
A mulcher turns stumps, small logs, branches, and brush into woodchips allowing natural decay to return them to the soil faster. Mulchers can be used for fuel management, right-of-way maintenance, invasive species clearing, property rehabilitation, and even tree felling (logs up to eight inches in diameter). Excavator-mounted units allow for reach into tough spots and safe access to slopes, while dozer/compact track loader units provide more power for quick work on flatter surfaces.

Saws
Feller bunchers are equipped with two main styles of heads: hotsaws and felling heads. A hotsaw is equipped with a continuously rotating disc that operates at high RPM. The weight of the disc and its row of carbide teeth (bolted to the saw at a right angle) ensure trees are cut quickly and effortlessly. As the tree is cut, a group of hydraulic arms grab the tree and lower it to the ground for processing or transport to the log deck via a skidder or yarder. Hotsaws can handle trees over two feet in diameter, and in smaller wood can grab trees in bunches due to independently controllable grab arms.
Felling heads are equipped with retracting bar saws like a processor, but the head itself is often designed more for shovel logging than simple cutting. Felling heads are increasingly common on self-leveling logging machines including those equipped for tethering. They allow an operator to cut, sort, and shovel wood while perched on a steep slope. Felling heads can handle timber close to and above three feet in diameter, making them an ideal choice to replace hand crews in rugged conditions.
Custom Fabrication
Peterson TSK
The one-of-a-kind Peterson-built TSK offers improved stability, increased performance, and reduced engine noise over previous track skidder models. This machine was purpose-built for the woods, and offers excellent ground flotation with available LGP tracks, easy maneuverability, and an independent swing boom and large grapple, perfect for grabbing large timber in difficult to reach spots.
Special Services
Need a machine for steep slope logging? Peterson’s Special Services division customizes feller bunchers for use with a cable assist system, and we offer customized boom and directional felling head packages for use in these challenging conditions.
Whatever your forestry needs, you can rely on the team at Peterson to deliver a machine that will work for you, and we’ll back that machine up with the product support and parts you need to keep running all season long!
