A plow bottom is configured to be easily reset when striking a rock while plowing. The plow operator may set the force required for the plow bottom to disengage using the adjustment switch. Once the shank strikes an object, the plow bottom will disengage. The plow operator then lifts the plow assembly using the tractor to raise the plow bottoms out of the ground. A spring then forces the disengaged plow bottom to reengage. Once the plow bottom is reengaged, the plow operator lowers the plow assembly and continues plowing the land.
