The ultimate tool for mechanised harvesting in New Zealand, our “Big Woodsman” will go to work on the most demanding trees and reliably produce clean stems and high-quality logs with speed and efficiency.
The Woodsman Pro 850 is engineered specifically for the most demanding and harsh forestry environments.
This 5.2-tonne (11,603 lb) powerhouse delivers superior single-pass delimbing, achieved by its four-knife design. The 850 features a main saw with a maximum cut diameter of 930 mm and a maximum delimb knife opening of 874 mm.
The Woodsman Pro 850 is suitable for 32+ tonne (70,548 lb) base machines. It is paired with our LOGGIC control system, ensuring superior performance, productivity, and ease of operator use.
- Continuous 360° rotation for manoeuvrability.
- Best-in-class single pass delimbing.
- Well concealed yet readily accessible hosing from machine arm to the control valve mounted in the head so downtime due to damaged hydraulic lines is kept to a minimum.
- On-board fault diagnosis for head and base machine.
- Optional 3-colour SED and LED colour marking system.
- Strong unyielding chassis with minimal wear to all pin connections after thousands of hours of harsh operation.
- Fabricated steel control valve bonnets providing easy access to main control valve and critical maintenance areas.
- Feed wheels feature reversible mounting to enable more even wear and prolong service life.
- Large range of service exchange parts available to minimise down-time.
- Main saw auto chain tensioning.
- Dual diameter sensors for increased diameter reading accuracy and reliability.
- Heavy duty delimb arms – two sets (upper and lower) are individually controlled.
- Maximum delimb knife opening is 874 mm.
- Top floating delimb knife and keepers feature replaceable wear pads to help avoid expensive rebuilds.
- One-bolt replaceable delimb knife insert tensioning system New Zealand patent application 777146
- Replaceable bolt-in belly wear plates.
- Knuckle design allows for large swing arc and excellent grease point access.
