An adjustable carrier system which aids in the lifting, lower, and transport of heavy objects by a vehicle such as an ATV. The adjustable carrier system generally includes a lower support which is adapted to be connected to a vehicle. A vertical support extends upwardly in a vertical orientation from the lower support. A winch includes a cable which extends through a lower pulley, upwardly alongside the vertical support, through an upper pulley, and downwardly alongside the vertical support to connect at its distal end to a sleeve. The sleeve is movably connected to the vertical support such that the cable may raise or lower the sleeve along the vertical support through use of a winch. A carrier for such as a basket or platform for holding an object is connected to the sleeve such that the carrier is also raised or lowered along the vertical support by the cable.
