A retractable wheel assembly includes arm assemblies, wheels, retraction arms, guide blocks, and a threaded shaft. The arm assemblies are hingedly attached to a lower frame of a utility vehicle. Each arm assembly comprises a first arm, a second arm, and a third arm hingedly linked therebetween. Each wheel is connected to the third arm of each arm assembly. The retraction arm is connected to the second arm, and a threaded shaft. The threaded shaft is configured to be actuated rearwardly where the retraction arm is rearwardly pulled helped by a guide block to convert the longitudinal movement to vertical movement, causing the second arm to fold the arm assembly inwardly when the trailer is positioned at rest. Then the threaded shaft is configured to be actuated forwardly where the retraction arm is pushed forward and helped by a guide block to convert the longitudinal movement to vertical movement causing the second arm to unfold the arm assembly outwardly to deploy the wheels for motion.
