Features

  • Three-Point rigid mounting for Category II and III -- Suitable for 50 to 150 HP tractors.
    Allows weight transfer onto backhoe when the hydraulic stabilizers are down and locks backhoe into position for maximum digging power.
  • Lower drawbar link locks standard for more stability in operation and transportation of the backhoe.
  • Bucket widths available range from 12" to 36".
    Buckets are heavy-duty with side cutting edges and "2A" size replaceable teeth for digging in all types of soil.
  • Optional ripper tooth for roots and frozen or compacted soil.
  • Patented Hydraulic Swing Cushioning slows and stops swing automatically at end of travel which prevents "Shock Load".
  • Dual double acting swing cylinders -- one pushing, one pulling, for a powerful, smooth and controllable full 180° swing.
  • Optional independent hydraulic system pump rated for 9 GPM.
