  • Patent number: 9969574
    Abstract: A wheelbarrow carrier provides transportation and dumping from a connection to a standard trailer hitch or tractor three-point mount. A pivoting ramp is used to load the wheelbarrow and a locking mechanism locks the wheelbarrow foot in place and the ramp in an upward position, once the wheelbarrow has been rolled onto the ramp and the ramp has pivoted from a downward position to an upward level position. The ramp pivots once the wheel of the wheelbarrow has rolled past the pivot point sufficiently to tip the ramp. Once the wheelbarrow is locked in the upward (level) position, a motor is activated to rotate a boom to which the ramp is attached with respect to a frame that is connected to the vehicle mount.
