A priority hydraulic flow diverter control assembly for a refuse collection vehicle hydraulic system provides proper and efficient flow in an auxiliary hydraulic circuit regardless of the primary flow so that refuse cart lifters and the refuse cart operate safely and efficiently. A pressure sequence valve diverts hydraulic fluid flow from the refuse cart lifter circuit into the downstream main hydraulic system when downstream back pressure is low, and into the system tank when back pressure is high. This allows all hydraulic operated equipment to operate at their intended speed whether at high or low system back pressure. A differential pressure sensing valve and flow regulating valves provide a precision flow. Harmful and undesirable vibrations and noise associated with pulses in hydraulic system pressure are reduced using a control orifice located in the valve body. A relief valve ensures that the diverter control assembly is compatible with other manufacturer's products.

A sweeper unit well-suited for use for sweeping paved areas includes a debris-retaining hopper with an associated fan assembly that includes an air outlet duct for connection to one side of a pick-up head and an inlet duct for connection between the other side of the pickup head and the debris-retaining hopper. A fan drive arrangement includes at least a first and a second hydraulic displacement device to drive the fan and, when required, provide a flow of hydraulic fluid for auxiliary devices including the gutter broom motor(s).
