COMPATIBILITY
Augers Compatible with BoRH Attachments
The BoRH™ is compatible with Aggressor® augers made with a
one- piece cast auger head. The auger head acts as the tooth
and pilot mounting platform. Below are things to look for when
determining if your auger is compatible with the BoRH™ system.
US Patent 7,669,673
• The height of the new pilot
adapter (Dimension A) is 2-1/2".
If this dimension is 1-1/2", then
the auger head was fabricated
and may not work well with the
BoRH™ attachment.
• If there is a weld bead in the
areas pointed out with B, then
the auger head was fabricated
and may not work well with the
BoRH™ attachment.
• The compatible 1 piece cast
auger head will have cast raised
lettering in Area C. The lettering
will have the auger diameter
followed by a “-AR”. Directly
below that will be a part number
that ranges from 137692
- 137697 depending on size.
If your auger does not have
those markings, then the Auger
Head was fabricated and may
not work well with the BoRH™
attachment.
NOTE: If the auger has
excessive wear, the lettering
may no longer be present. In
those cases, refer to A & B to
determine compatibility.
