QS450

4 x 4 equals increased traction, torque, and delimbing force. Ideal for harvesting, processing, thinning, and debarking operations.


The QUADSTAR harvester processor range is heavy duty and built to last.

The QS450 is designed for small sized wood with an optimum operating size of 14-18” in diameter. This multi tree processor is packed full of design features that set it apart from the competition.

4X4

4X4 extra wide feed rollers for increased surface contact with the log. Large diameter wheels for increased speed.

Side Stepping

Innovative patent pending Side Stepping drive feature allowing for independent control of two stems. This allows the operator to align butts, trim defects out of one stem but not the other and or, process one stem and not the other.

Dual find end

Dual find end sensors to eliminate waste when multi tree processing.

Wide Chassis Structure

Wide Chassis Structure for improved structural strength and increased single and multi-tree processing capacity.

Hose Through

Clean Hose Through design with Taimi swivel or 360 rotation option to better protect hoses.

Taper Lock Collar

Large diameter pins with Taper Lock Collar design for decreased wear and increased life expectancy.

DGlide

State of the art DGlide bushing material for extended life and durability of pins.
