The PATAS System
Especially developed for the careful pruning (delimbing) of larch, pine, spruce, Douglas fir, eucalyptus, poplar, and teak—the PATAS handles pre-pruning (delimbing), live-tree pruning (delimbing), and small-scale harvesting from a single tractor-mounted platform.
See It in Action
The cutting head reaches operating speed via hydraulically driven rubber belts that guarantee minimal bark pressure and maximum grip throughout the full range of the trunk. Pneumatically adjustable blades separate every branch cleanly, without risk of injury to the cambium.
The remote-controlled system keeps the operator safely on the ground at all times. One operator handles the remote; a second manages positioning. Together they can process 30–50 trees per hour in European plantation conditions.
Dual Function
Forestry experts who observed the PATAS in the field reached the same conclusion: "The selection of crop trees must be completely rethought as soon as this machine is deployed."
Trees destined for felling can be pruned (delimbed) by the PATAS—whether that harvest is next week or 20 years from now. The lower 40–50 feet (12 to 15 meters) remain branch-free, eliminating the need for a full harvester or post-felling manual pruning (delimbing) in most cases.
That means lower operating costs, faster extraction, and better log quality at the mill—all from equipment that pairs with a standard 40 hp tractor you may already own.

Specifications
Compatible Species
The PATAS Climber mechanical pruning (delimbing) system is engineered for the softwood and plantation species where knot-free timber production delivers the greatest economic return. Compatible species include:
Nova Scotia and New Brunswick are among the most white pine-dense regions in eastern Canada, making them strong markets for production pruning with the PATAS Climber. The combination of established timber ownership, active forestry contractor networks, and premium clear pine demand at Atlantic mills creates an ideal environment for mechanical high-pruning (delimbing) operations.
