The portable pipe thrusting apparatus includes a collar configured to releasably grip the pipe, a support frame, at least one rear leg assembly coupled to a rear end of the support frame, and a bi-directional driver coupled to the collar and the support frame. The rear leg assembly is configured to move the rear end of the support frame between a lowered position and a raised position to align the pipe for the thrusting operation. The bi-directional driver is configured to drive the collar toward and away from the earthen formation to insert and remove the pipe from the earthen formation.
