Abstract: A suspension assembly for a carriage includes a first torsion assembly connected to a second torsion assembly in parallel such that force delivered to the first and second torsion assemblies through the wheels is distributed between the first and second torsion assemblies.

Abstract: An improved wheeled support assembly for a trailer spraying device including a tank for liquid to be sprayed mounted on a main frame of the device, and a spray assembly adapted to spray liquid from the tank in a predetermined pattern through a spray boom projecting from both sides of the frame. Two large wheels are mounted on each side of the main frame by a rigid wheel adapting frame fixed to the main frame that comprises two elongate support members each spaced from a different one of the sides of the main frame to provide wheel clearance spaces between those elongate support members and the sides of the main frame.

Abstract: A bracket for securing an end portion of a flexible agricultural chemical delivery tube along an end portion of an elongate rigid seed tube on a planter. The elongate bracket has a rear surface adapted to be positioned along and in contact with the front surface of the seed tube, and has a longitudinally extending row of sockets opening through its rear surface that are adapted to receive protrusions projecting above the front surface of the seed tube. The sockets are defined by surfaces adapted to engage those protrusions to retain the position of the bracket along the front surface of the seed tube. Along a front surface of the bracket are members adapted to receive and retain the end portion of the flexible chemical delivery tube.
