Actuator Slidably Connected To Tool Patents (Class 172/503)
  • Soil leveling apparatus with improved frame and hitch
    Patent number: 5771980
    Abstract: An improved soil leveling apparatus includes a hitch (202 or 302) for connecting the frame to the loader arms and tilt cylinder(s) of a skid steer loader. The hitch (302) includes a hitch plate (304) that can selectively be made rigid with the frame or can selectively be allowed to pivot fore-and-aft relative to the frame. This allows the operator to select the rigid orientation of the frame when it is desired to have the frame be rigid relative to the loader or to select the floating, pivotal orientation depending upon ground terrain and other factors.
