QS505 Grapple Processor

4X4 equals increased traction, torque, and delimbing force.

The QUADSTAR grapple processor is heavy duty and built to last.

The QS505 Grapple processor is designed to be able to sort, shovel and load like a grapple and process, measure and cut with all the advantages of a Southstar processor. Combine your loading and processing into one effective machine. The QS505 is designed for small to medium sized wood with an optimum operating size of 18-24” in diameter. This large multi tree grapple processor is packed full of design features that set it apart from the competition.

Grapple delimb arms

Extra large grapple delimb arms to maximise capacity while retaining delimbing excellence. Unique drive arm design fold out when loading for extra capacity.

Tilt lock system

Powerful tilt lock system - activated with twin cylinders allowing this grapple processor to operate without a heel attached.

Tilt leveling software

Combined with innovative tilt levelling software to control logs when loading from back of trailer or handling wood off centre.

Dual rotate motor drive

Powerful dual rotate motor drive allows operator to rotate logs up steep slopes and when loading trucks on uneven ground.

4x4 drive system

Powerful 4x4 drive system providing amplified torque in large wood when processing, while increasing productivity with the ability to multi-stem small wood.

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 wastage when multi tree processing.

Dasa 5

Controlled with proven DASA 5 computer system combined with Southstars unique Startrax satellite communication system.

Taper Lock Collar

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


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