ABSTRACT:
A digging and planting machine is provided having a tubular digging and planting tool, and at least one sensing and signalling means for sensing the resistance below and/or exceeding a predetermined minimum of the ground to penetration by the digging tip of the tool, thus gauging the condition of the ground, and detecting obstacles to such penetration, so as to ensure that the digging tip provides and a plant is fed to a planting hole of the desired depth, when ground condition is suitable, and, when ground condition is not suitable, that a digging attempt is aborted and a new attempt made as soon as possible.
