off road farm jack:

The farm jack is characterised by rugged, simple construction.
The jack's versatility stems from the fact that it can be used for such applications as lifting, winching, clamping, pulling and pushing. It is this versatility, along with the long travel it offers and its relative portability, which make the farm jack so popular with off road drivers.
