Abstract: A blower unit having a frame and at least one wheel on the frame through which the frame can be supported upon and moved over a subjacent support surface. A handle assembly has at least one gripping region that is configured to be engaged by a user situated at the rear of the blower unit. A source of pressurized air has an outlet at which a volume of pressurized air is discharged. A pressurized air handling system on the frame has a conduit assembly defining first and second flow paths through which pressurized air from the outlet of the source of pressurized air is selectively delivered respectively to first and second outlets. The pressurized air handling system further has an air control with at least first and second states in which different volumes of pressurized air are delivered to the first and second outlets.

Abstract: A method of setting up a system to redistribute loose material; including the steps of: obtaining a blower assembly that is configured to generate a pressurized supply of air that is discharged at an outlet; obtaining a wheeled carrying unit for the blower assembly; and operatively positioning the blower assembly on a frame on the carrying unit. The carrying unit and blower assembly are configured so that with the blower assembly operatively positioned the carrying unit can be advanced by the user over the subjacent support surface to thereby cause pressurized air generated by the blower assembly to be directed to continuously and controllably redistribute loose material residing on the subjacent support surface.

Abstract: A carrying unit for a source of pressurized air having a frame and at least one wheel on the frame through which the frame can be supported upon and moved over a subj support surface. A conduit assembly is part of a pressurized air handling system on the frame and has an inlet for receiving pressurized air from a source and first and second spaced outlets for discharging pressurized air directed through the inlet. The pressurized air handling system further has an air control system that is changeable selectively into different states. By reason of changing states, the air control system causes at least one of: a) a different volume of air from the inlet to be directed to the first and second outlets; and b) a change in a direction of air discharging from one of the outlets.
