Tigercat’s New PD26 Delimber Tackles Trees Up to 26 Inches With Knuckleboom

Tigercat Industries has introduced its new PD26 pull-through delimber, designed to delimb and top tree-length logs in conjunction with a Tigercat knuckleboom loader.

The open-frame design combines a heavy-duty slew system, smooth feeding geometry and service-friendly features that help operators maintain consistent production while reducing maintenance-related downtime, the company says.

Powered by a 63cc gear motor with dual-tapered roller bearings on the output shaft, the compact saw maximizes the cutting envelope. The PD26 can delimb trees up from 4 to 26 inches in diameter.

The large main slew bearing with ¾-inch M20 bolt-through connections on both the inner and outer race eliminates the need for support rollers, providing smooth operation and performance. Heavy-duty round tubing on the main frame reduces snagging and material hang-ups for smoother stem flow, while the sloped surfaces and open-frame structure sheds debris. Abrasion-resistant wear plates enhance durability.

The bolt-on front knife features replaceable backing nuts for simplified servicing. The knives can be easily swung into position without interference thanks to the open frame, eliminating the need to field weld these components. All movable knife blade welds are external and fully accessible, allowing for faster maintenance and replacement.

Tigercat equipped the PD26 with a 6-gallon bar oil reservoir for extended operating time between refills. The tank also includes an inline outlet strainer, bolted cleanout flange and bolt-on design for easy removal when service is required. 

A centralized hydraulic manifold and optimized hydraulic circuit allows for function adjustments and servicing to be completed from inside the cab or safely away from moving components. Advanced hydraulics eliminates the need for an accumulator.

Hydraulic auto tensioning for the chain comes standard, or a manual tensioner is also available upon request. Additional features include debris protection for the bar cylinder connection, a saw position flag, a chain catcher and chain-shot guarding.
