4 x 4 equals increased traction, torque, and delimbing force. Ideal for harvesting, processing, thinning, and debarking operations.
The QS450 is designed for small sized wood with an optimum operating size of14-18” in diameter. This multi-tree processor is packed full of design features thatset it apart from the competition.
Features may include:
Wide frame structureWide frame design for structuralstrength resulting in a reductionin frame cracking. This also allowsfor improved hose routing withminimal exposed hoses.
Front knifeExtremely tough fixedfront knife.
Touch-less encodersMagnetic touch-less encoders forbetter accuracy and extendedlife duration.
BushingsD-Glide bushing material forextended life and durability ofmain pins.
Spring linkInnovative spring timinglink to allow for variationin multi stem diameterswithout loss of drivetraction.
Delimb armsFabricated delimb armswith replaceable highwear resistant alloycutting edges.
Delimb tipsExtended delimb tips and pop angle forease of picking from the stack.
Drive teethBidirectional drive teethdesign for optimum grip inboth forward and reverse.
Tami SwivelHose through design tobetter protect hosing. Standardon every model.
CylindersHigh pressure heavy wallcylinders with halite packing kits.
Lock pinsLarge diameter with expanderlock pins for decreased wear andincreased life.
Measuring wheelExtra wide measuring wheel allowsoperator to accurately measure bothsingle and multi-stems.
Side stepping driveInnovative side stepping drivefeature allowing for independentcontrol of two stems.
This allows the operator to alignbutts of multiple stems, trimdefects in one stem but not theother, and or process one stemand not the other.
Laser find end sensorsDual find end sensors to eliminatewastage when multi-stemming.
Feed rollersFour wide feed rollers forincreased surface area when inmulti-stemming application.
