A method of converting a wheelbarrow comprising:
- (a) providing a wheelbarrow comprising:
- a tray having a base with an underside, and an upper rim;
- left and right-side wedges, having top surfaces and bottom surfaces, the top surfaces attached to the underside of the tray;
- left and right-side handles, comprising grips at back ends and a front stop that couples front ends together, further comprising top surfaces and bottom surfaces, the top surfaces attached to the bottom surface of the wedges;
- a front brace coupled to the underside of the tray, and the topsides of the handles;
- a stand coupled to the bottom surfaces of the handles;
- an axled wheel and left and right axle brackets coupled to the bottom surfaces of the handles;
- first factory bolts within a first channel system traversing through the front brace, the handles, and the axle brackets;
- second factory bolts within a second channel system traversing through the handles and the axle brackets;
- third factory bolts within a third channel system traversing through the tray, the wedges, the handles and the stand;
- and fourth factory bolts within a fourth channel system traversing through the tray, the wedges, the handles, and the stand;
- (b) removing the first, second, third, and fourth factory bolts from their respective channel systems;
- (c) providing left and right-side risers comprising front and back ends, and top and bottom surfaces defining a height of between 1-4 inches, and first, second, third, and fourth channels;
- (d) inserting the risers below the handles such that the top surfaces of the risers abut against the bottom surfaces of the handles, and the risers first, second, third, and fourth channels align with the first, second, third, and fourth channel systems respectively;
- and
- (e) providing new first, second, third, and fourth bolts that are longer than their respective factory bolts by at least the height of the risers and inserting said new bolts into their respective channel systems such that the stand and axle brackets couples to the bottom surfaces of the risers;
- and the bottom surfaces of the handles couple to the top surfaces of the risers.
