A wheelbarrow with a mixing assembly for mixing aggregate building products. The wheelbarrow has a base assembly and an open hopper mounted on the base assembly. The mixing assembly has a mixing blade positioned within the hopper, and a motor. A motor housing is positioned under the hopper, within the base assembly, and houses the motor. A shaft extends from the mixing blade through the bottom surface of the hopper into the motor housing. The shaft connects the mixing blade with the motor, and allows for rotational movement of the blade to effect cutting grooves into the aggregate substances within the hopper when the motor is activated.

1. A wheelbarrow with a mixing assembly for mixing aggregate building products, comprising: a wheelbarrow, the wheelbarrow having a base assembly and an open hopper mounted on said base assembly, the base assembly having a pair of horizontal supports, each support having a top surface, and a pair of legs extends vertically downward from each support, wherein the hopper is bowl shaped having a hopper diameter and a hopper inside wall, the hopper having an outer surface, an inner surface, and a bottom surface, wherein the bottom surface of the hopper is secured to the top surface of the horizontal supports; and a mixing assembly, the mixing assembly having a mixing blade, a motor, and a shaft extending between the mixing blade and the motor, wherein the mixing blade is positioned horizontally within the hopper for rotational movement therein about a vertical axis, the motor is positioned between the base assembly legs under the hopper, wherein the mixing blade comprises a horizontal arm having a bottom surface and having two halves, each of said halves having a plurality of substantially rectangular tines extending vertically downward from the bottom surface of the horizontal arm toward the bottom surface of the hopper, wherein the tines of the first half are offset from the tines of the second half, wherein each tine is set at a slight angle, thereby enabling said tines to cut grooves into the mixture contained within the hopper during rotation, in order that as the mixing blade rotates, the tines of the second half cut grooves into the mixture between the grooves cut by the tines of the arm's first half, thereby allowing water to infiltrate the mixture within the hopper, and wherein the arm has a length slightly shorter than the hopper diameter so as to allow the mixing blade to freely rotate within the hopper. 2. The wheelbarrow with mixing assembly as recited in claim 1, wherein the tines include an outermost scraping tine which is attached to the horizontal arm and extends downward therefrom but is mounted in close proximity to the hopper inner surface and shaped to conform to the hopper inside wall to prevent unmixed aggregate from adhering to the hopper inside wall during mixing.3. The wheelbarrow with mixing assembly as recited in claim 2, wherein the outermost scraping tine has a leading edge, said scraping tine being convex and angled towards the tine leading edge.4. The wheelbarrow with mixing assembly as recited in claim 3, wherein the tines are angled between extending transverse with the horizontal arm and longitudinal with the horizontal arm, in order to facilitate cutting grooves in the mixture.5. The wheelbarrow with mixing assembly as recited in claim 4, further comprising a motor housing in which the motor is housed, the housing positioned between the base assembly legs under the hopper, said housing protecting the motor from damage.6. The wheelbarrow with mixing assembly as recited in claim 5, wherein the motor has a chain linking the motor to the shaft, said chain producing rotational movement of the shaft, thereby causing the mixing blade to rotate within the hopper.7. The wheelbarrow with mixing assembly as recited in claim 6, wherein the shaft extends vertically downward from the horizontal arm bottom surface through the hopper bottom surface into the motor housing.8. The wheelbarrow with mixing assembly as recited in claim 7, wherein the wheelbarrow further comprises a plurality of braces, the braces each extending from one of the horizontal support top surfaces to the hopper outer surface, said braces securing the hopper to the base assembly of the wheelbarrow.
