The hydraulic lift boom attachment including a support frame and a telescopic lifting arm wherein the support frame is coupled to a tractor's three point hitch which hydraulically raises or lowers the support frame. The telescopic lifting arm has one end coupled to the support frame and the other end is coupled to the tractor's draw bar via a pulley assembly to rotate such other end of the telescopic lifting arm when the support frame is hydraulically raised or lowered. Furthermore, the support frame of the hydraulic lift boom attachment includes a telescopic vertical support assembly to vary the vertical height of the telescopic lifting arm.
