Meet the Leader in Size, Power and Versatility

When it comes to power, performance, comfort and serviceability the RT-120 has it all. This machine was built to be a leader in a variety of applications and it’s been built to last.


Prepare to Overachieve


A Cummins 3.8-liter, turbocharged diesel engine powers the RT-120. This 120-horsepower engine produces 360 foot-pounds of torque, which is transferred to the terrain through direct-drive hydraulic motors, allowing the machine to easily move through its path.


The RT-120 achieves superior performance over competitive machines. The unit features a rated operating capacity of 3,745 pounds (1699 kg) and a tipping load of 10,700 pounds (4853 kg). It features ASV’s patented Posi-Track® rubber-track suspension—well known for its smooth ride—and includes both suspended wheels and axles, allowing it to achieve faster speeds over all types of terrain. The fully-flexible track and suspended wheels conform to the ground, ensuring maximum traction in the roughest conditions. The features, combined with the RT-120’s 15 inches of ground clearance, allow the unit to work in more places, on more days and more comfortably than competitive machines.


Standard joystick controls make operation easy and intuitive. The machine’s cab is pressurized for a clean operator environment. Buyers can also choose an optional all-weather cab that includes heat and air-conditioning.


ASV designed this machine to give operators easy access to the reliable Cummins engine through a three-panel hood and tilting cooler arrangement. The design, paired with sight gauges for both hydraulic oil and coolant, simplify routine inspections of filters, oil and normal service items. The rearward tilting cab and hinged bellypans provide easy accessibility when further service is required.
