Equipment Overview
The Liebherr PR726 is a medium dozer built for heavy pushing and precision grading, part of Liebherr’s Generation 8 crawler dozer range for the Australian market. It has 125 kW (170 hp) of rated net power, an operating weight of 17,658 kg, and a 3.33 m³ six-way blade in standard XL configuration, suited to civil construction, landfill, and site development work where grading precision and low ground pressure matter.
Power comes from the Liebherr D 934 A7 engine, a 4-cylinder, 7.0-litre unit that meets Stage V/EPA Tier 4f emission standards. An infinitely variable hydrostatic travel drive gives each track its own independent motor, delivering continuous traction and speeds up to 11 km/h, while hydrostatic steering and a wear-free multi-disc parking brake round out the drivetrain. A three-shank ripper is available as a rear attachment for scarifying compacted ground.
