Pendulum Arm SuspensionWith the pendulum arm suspension technology, the operator can maneuver the machine in the tightest of thinning areas.
Caterpillar 3126 DITA Engine & Transmission
Caterpillar offers a line of some of the most powerful Harvesters for worldwide use.
TransmissionEach Cat Harvester features an all-wheel drive fully hydrostatic transmission.
StandardsThe Caterpillar 3126 DITA Engine performs at the full-rated flywheel power, meets all current and proposed worldwide emissions standards up to the year 2002 and is approved for worldwide use.
Torque RiseThe unit-injected fuel system provides a controlled fuel delivery increase as the engine lugs back from rated speed.
TurbochargerThe turbocharger enhances performance and engine efficiency, especially at high altitudes, by packing more air in the cylinders for excellent combustion.
Jacket Water AftercoolerJacket Water Aftercooler reduces smoke and emissions by providing a cooler, more efficient combustion.
Unit InjectorsIndividual, high-pressure unit injectors atomize fuel efficiently for fast response and increased fuel economy with low emissions.
Fuel CleanlinessThe fuel pre-filter and water separator element combined with two, high-efficiency fuel filters, in series, ensure excellent fuel cleanliness for extended injector and fuel system life.
Camshaft Roller FollowersCamshaft roller followers reduce wear and frictional power losses for excellent fuel economy.
PistonsTwo-piece articulated pistons with forged steel crown and forged aluminum skirt provide durability, low engine sound levels and enhanced fuel efficiency with improved thermal and structural capability.
Chrome Ceramic SurfaceThe new Chrome Ceramic Surface (CCS) ring package, specifically developed for high load/high temperature applications, significantly improves engine block life.
CrankshaftThe crankshaft is forged and induction hardened for long-term durability and is completely regrindable.
Block DesignDeep skirt engine block design ensures rigidity and reduces vibration.
