Specifying the Unit
The 4 bolt mounting plate allows the fitment of brackets
to suit most diggers in the quoted range. It is essential to
confirm the pin diameter (D), width of boom (W), and pin
pitch (C) before ordering. Not all quick hitches will be
suitable for use with the Postmaster, although those
designed for hammer operations should be suitable –
please check with the supplier first.
Standard post clamps can be adjusted for post size and specials can be devised where
possible.
Posts can be wood, metal, GRP or concrete, but special clamps will be needed. Posts may not
need points but this can help in hard soils. Clearly some soils will be too hard for successful
operation, but the use of a steel pilot or rock auger can usually solve the problem. Generally,
pilot holes should be 30% smaller than the post to ensure a good tight installation.
