I recently found out about a three bottom walking plow that is claimed to be made by oliver. First and foremost is there such a thing as a three bottom walking plow and if so would oliver even have tried to produce such a thing, it has wooden handles like a regular walking plow and it has no rear wheel , it also has two depth adjustment handles that face towards  the rear,  any information on this subject would be gold <!-- s:shock: --><img src="{SMILIES_PATH}/icon_eek.gif" alt=":shock:" title="Shocked" /><!-- s:shock: -->
