Accurate length/diameter measuring systems

Patented length-measuring wheel cylinder design ensures constant pressure to closely follow stem irregularities and a find end photocell sensor provides excellent accuracy. Four-point diameter measuring system ensures superior diameter measurement.

MaxiXT smart control system

State-of-the-art control system with intuitive graphical interface to manage all aspects of head control and performance. Easy programming of individual operator control preferences plus production parameters such as tree species, length and diameter.

Support you can count on

Technology that works as hard as you do

MaxiXT smart control system

The MaxiXT smart control system is designed to enable fast, accurate execution of even the narrowest of cutting windows. The power of the knives, feed rollers and tilt down function are determined by stem diameter and tree species, and are easily adjusted using a graph. This helps optimize your productivity, measurement accuracy and time savings.
