The RT-75 HD is built to get more done, especially in forestry and mulching applications, while requiring less maintenance. Like the RT-75, the HD is engineered with a next-generation MAX-Series cab and patented Posi-Track® technology and provides the industry’s highest ground clearance, lowest ground pressure, longest track life and best traction over all types of surfaces—and it offers some heavy-duty extras, too.The hydraulic system in the HD is highly efficient, including 35.7 gpm high flow and 3,300 psi.
