Abstract

The present invention has found that a single hydraulic control can drive the unfolding and height adjustment circuits in parallel. In a preferred circuit this can be accomplished using pressure responsive valves to ensure a correct setup sequence. In accordance with the invention there is provided a method for hydraulically unfolding an agricultural sprayer from a single hydraulic drive circuit, the sprayer including a pair of pivotally mounted wings comprising main booms, supported on caster wheels having wheel locks, and secondary booms rotatably secured on the main booms for selective height adjustment, the method comprising the ordered steps of : releasing the caster wheel locks to allow the wings to move pivotally; actuating a hydraulic drive for unfolding the wings from an aligned transport position to a transverse operational position; and, actuating a hydraulic drive for positioning the secondary booms in a field position.
Advantageously, a sprayer including the hydraulic controlled setup sequence of the present invention provides simple, accurately sequenced operation requiring only one hydraulic spool of the tractor. In addition, the set up can be accomplished in less time, requiring less space.
