The present invention is a walk-behind power unit stabilizing system for use on portable trenchers and other equipment. The preferred application comprises a retractable wheel assembly mounted at the rear of a trencher where the invented device is allowed to be maneuvered by the user from a lower, stabilization position to an upper, transport position. The device has a handle that allows the user to move the device from the upper, transport position to the lower, stabilized position, and vice versa, easily by raising and lowering the handle, either by hand or by moving the handle up or down using the user's foot. Some of the main benefits of the invented device include: ease of use; a reduction in the physical labor required to operate a trencher; stability; the ability to more consistently control the depth at which the trench is dug; an increased ability to traverse perpendicular trenches; increased force exerted on the boom when inserting the boom into the ground; and trench straightening.
