The 74-hp (55.2 kW) RT75 has the compact size and muscle you need for tight residential or commercial jobsites. And you can throw that muscle around in a variety of ways with an assortment of trenchers plus saw, backhoe, vibratory plow, reel carrier, and combination trencher/plow attachments.
KEY FEATURES, RT75
- Solid backfill blade lift arms and cast blade pivot increase structural strength of the backfill components.
- Planetary axles with locking differentials make maximum use of torque at the wheel and offer high ground clearance.
- Four-point tie-downs (at each corner of the machine) provide increased hauling security.
