steel sections. The main support elements are two longitudinal members connected with
crossbars. Load box (2) is welded to the frame. Manure spreader suspension consists of two
wheel axles (3), in a tandem arrangement suspended on taper leaf springs connected by
rocker arm (4). Axles are secured to suspension springs using absorber plates and U bolts.

cone bearings. The wheels are single, equipped with brake shoes activated through
mechanical expander cams.
