Optional Equipment
A range of additional attachments are available for a variety of different posts and conditions.
They are:
1. Flow Divider for higher flow machines – For hard to reach jobs a larger machine is
sometimes necessary. To protect the motor and seals it can be necessary to add a flow
control option to prevent internal damage.
2. Mounting Bracket to fit Loaders – a special bracket so that the Postmaster can be used
when mounted on loaders and hangs level.
3. Rock Spike – A rock spike can be supplied to act as a pilot for the post. This can be
gripped by the standard jaws. Standard size 60mm diameter 1m long
4. Dibber – To create a concrete back fill hole and leave the central bar in place. A 250 x
150mm compacted void is left in the ground and either a length of re-bar or angle is let in
the ground. The advantages are no soil away and a compacted hole prepped for cement.
