The Posi-Track RT-75 Heavy-Duty compact track loader is a customization of the ASV RT-75. It has a 75-horsepower Cummins diesel engine that produces 221 lb.-ft. torque.
The HD features upgraded durability and optimizations for forestry work. These include metal guarding against brush and debris around key areas, such as lights, the AC condenser and rear screen. The machine blows debris from mulching applications out of the engine compartment screens with a hydraulically driven, auto-reversing cooling fan. A full rear brush guard is also available as a factory-installed option.
