World-First Mechanical High-Delimbing Machine
The advaligno PATAS climbs a tree, delimbs to 40–50 feet (12–15 meters), and returns to the ground in eight seconds. We bring this German-engineered system to the US and Canadian markets.
The Technology
Until now, high delimbing above 16 feet (five meters) meant slow, dangerous manual labor with expensive crews. The PATAS—named after the world's fastest climbing primate—changes the economics of timber production entirely.
Hydraulically driven rubber belts grip the trunk with minimal bark pressure while precision blades cleanly remove branches up to 1.4 inches (3.5 cm) in diameter. The entire process takes eight seconds per tree. A two-person crew can process up to 20 trees per hour.
The system mounts to any standard tractor with a Category 1 or 2 three-point hitch and 40 hp minimum—equipment most timber operations already own.
Full Machine DetailsWhy PATAS
Knot-free, branch-free timber commands premium prices. With PATAS you can delimb more crop trees per hectare than ever before—significantly expanding the share of your stand that produces high-grade wood.
Manual crews average four to six trees per hour. The PATAS delivers up to 20. That productivity gap means the machine pays for itself quickly and opens new service revenue streams for forestry contractors.
Remote-controlled operation keeps workers safely on the ground. The belt-drive system applies minimal bark pressure, and biodegradable hydraulic oil (PANOLIN HLP SYNTH 32) is standard—not optional.
Dual Use
The PATAS does not just grow value in standing timber—it also works as a compact harvester on trees slated for felling. Delimb the lower 40–50 feet (12 to 15 meters) before the cut, and you eliminate the need for a full harvester during extraction.
It does not matter whether the tree comes down next week or in 20 years. The lower trunk stays branch-free from the moment the PATAS passes over it, protecting your investment in future crop trees and saving time at harvest regardless of when that day arrives.

Common Questions
A mechanical high-delimbing machine removes branches from standing, living trees at heights above what manual pole saws can safely reach. The PATAS Chasse by advaligno is the world’s first such system for commercial production pruning — it climbs a tree to 40–50 feet (12–15 meters) and removes all branches cleanly in approximately 8 seconds. It mounts to any standard farm tractor and requires two operators. Patas Forestry, a Baker Forestry company, holds exclusive distribution rights for the PATAS Chasse across the United States and Canada.
The PATAS Chasse removes branches from the lower 40–50 feet of standing crop trees, preventing new knot formation as the trunk grows. Knots are the primary defect that separates commodity lumber from premium clear grades. Research published by Maine Forestry and the Harvard Forest Bulletin shows that production pruning increases stumpage values by 20–25%. Clear, knot-free lower logs consistently command the highest prices at the mill and at veneer-quality auctions.
The PATAS Chasse was specifically engineered for larch, pine (loblolly, white pine, lodgepole), spruce, Douglas fir, eucalyptus, poplar, and teak — the commercial softwood and plantation species where knot-free production has the highest economic return. It works on trunks between 4 and 10 inches (10–25 cm) in diameter with branches up to 1.4 inches (3.5 cm).
The PATAS mounts to any standard tractor with a Category 1 or 2 three-point hitch, 40 hp minimum, and a 1-3/8 inch 6-tooth PTO shaft at 540–600 RPM. The full system weighs approximately 1,250 lb (570 kg). Most timber operations and forestry contractors already own compatible equipment — no dedicated vehicle purchase required.
