摘要： A backhoe pivotally supported from a prime mover is disclosed wherein the hydraulic cylinders operably connected to the outrigger stabilizers are provided with a detent to maintain the outrigger stabilizers in an elevated transport position until being pressurized to extend the cylinders and, thereby, rotate the stabilizers into a ground engaging position. The detent is in the form of a projection extending inwardly from the barrel of the outrigger stabilizer cylinder and positioned for engagement with a deformable detent ring when the piston is moved to the fully retracted position. The detent includes a relief to permit the flow of hydraulic fluid past the engagement between the detent ring and the projection so that hydraulic cylinder will not become hydraulically locked.
