The PR 766 is the latest Generation 6 dozer offered by Liebherr. It weighs from 101,854 to 119,491 lbs. and is powered by a fuel-efficient 422-hp, eight-cylinder, V-engine that meets Tier 4 Final without a diesel particulate filter. The hydrostatic drive enables the speed of the diesel engine to be kept constant in practical use regardless of the required load, meaning it always runs at the optimum efficient speed. Essential drivetrain components are developed in-house and optimally coordinated, which increases the system efficiency.
