Round Adapter 107mm (4")

Remove the standard tube using a 6mm hex key to unscrew the 8 bolts & locking washers. Slide the standard tube off the base of the Post Driver. Slide the Magnum Adapter into its place & attach using the same bolts & washers. Remember to use a Locking Compound on the screw threads to stop them vibrating out.

The maximum capacity of the machine is 4” round diameter.

Our largest adapter is 107mm internal diameter.

When the ground is very dry, compacted or stoney, you will need to make a pilot hole for posts larger than 78mm. This can be either by hand using a Pilot-Bar, or mechanically using either our Pilot Core tool or an earth Auger. Posts smaller than 78mm should not need a pilot hole.
