Ground conditions
The Post Driver has excellent performance in most ground conditions. Small to medium
stones will generally displace. If a larger stone is struck and the post is not progressing, cease
driving, remove the post and move along a short distance and retry.
The Post Driver will not drive a post through solid rock. This is beyond the limits of a small,
lightweight machine and most posts.
Large Diameter Posts; for posts larger than 85mm diameter a Pilot Hole is sometimes
required. This can be achieved by hand using a standard Pointed Steel Bar. This creates a
guide for the post and displaces some of the soil, making the work easier for the Post Driver.
Dry or Compacted/Hard Ground; if the ground is very dry, compacted, or hard composition
(e.g. clay / chalk) a larger pilot hole may be required for posts larger than 80mm. Use the
Pilot Core Tool to achieve a 50mm pilot hole. Fill this hole with water and leave to soak. This
will greatly improve the post driving results.
