Let The Big Dog Eat


A Cummins 3.8-liter, turbocharged diesel engine powers the RT-120 Forestry. This 120-horsepower engine produces 360 foot-pounds of torque which is transferred to the terrain through direct-drive hydraulic motors that moves through anything in its path.


The RT-120 Forestry features a rated operating capacity of 3,535 pounds and a tipping load of 10,100 pounds. It offers ASV’s patented Posi-Track® rubber-track suspension and includes both suspended wheels and axles, allowing it to achieve faster speeds. This machine offers a fully-flexible 20” tracks and suspended wheels that conform to the ground and a special guarding package. Combine that with 15 inches of ground clearance and you get a unit that works in more places, on more days, 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 receive an all-weather cab that includes heat and air conditioning, level 2 FOPS protection, and forestry spec ROPS/OPS. An AM/FM/MP3 audio system is also included.


The RT-120 Forestry gives operators easy access to the Cummins engine through a three-panel hood and tilting cooler arrangement. This machine offers a hydraulic quick attach and a design that simplifies routine inspections of filters, oil and normal service items. The rearward tilting cab provides easy accessibility when further service is required.
