Abstract
A dual disc cultivator cutaway (10) is disclosed including a frame (30) pivotally mounted to a cultivator tool bar (14) through a bar mount (22). A spindle (38) is pivotally mounted to the opposite end of the frame (30) and slideably mounts first and second arms (40) which in turn rotatably mount the disc blades (44). An adjustment slide (46) is removably pivotally mounted to the upper arm (26) of the cultivator gang assembly and is adjustably, slideably fixed on a bar (45) extending from the spindle (38). Thus, movement of the frame (30) is in a fixed positional relationship with the gang assembly in the cutting and transport positions and pivots with the gang assembly relative to the tool bar (14). When the slide (46) is not attached to the upper arm (26), the frame (30) can be held in an inoperative position relative to the tool bar (14) by a latch (54) pivotally mounted to the tool bar ( 14) through the bar mount (22) which hooks on a pin (56) attached to the frame (30). In the inoperative position, the frame (30) is supported by the tool bar (14) independent of the gang assemblies.
