Your search is over. The Polar Bear is by far the most supreme machine for bulking work on the market today and with operating features and benefits as impressive as these, you’ll be blown away by the Polar Bear’s performance.

  • Skilfully engineered Cross-Leveller provides an advantageous 3° side tilt - left and right. As a bonus, these Cross-Levellers also function as dual lift which alters the cutting angle allowing for a different angle of contact to the earth. Generous clearance to the underside of the machine is also achieved.
  • Enjoy ultimate performance and driver comfort with an X-Series Cushion Hitch and incorporated Cup on the Polar Bear. You’ll be glad for this standard inclusion arrangement on such a hefty machine.
  • Your safety is our priority which is why we’ve included, as a standard feature on the Polar Bear, a Sequence Valve marrying the Apron / Tailboard functions together. This acts as a fail-safe, preventing damage to the machine by eliminating potential incorrect operation.
  • Single row rippers tickle the ground helping to contain weeds and assist in getting a load full of dirt.

Boost the already impressive working specifications with modifications from our range of optional inclusions to customize the Polar Bear just how you like it:

  • An optional 50mm tyne Ripper system with the choice of single (9) or double row (11) tyne configuration
  • Bolt on Stinger Blade allowing for a more aggressive cut.
  • Tandem Hitch option, giving you the ability to double your work, not your effort.
