Abstract: A mobile tower for use with an irrigation system having horizontally-extending spans, the mobile tower comprising a frame and a number of wheels. The frame includes a crossbeam, first and second diagonal legs, first and second lower gussets, and an upper bracket. The crossbeam, first diagonal leg, and second diagonal leg include tubular members having gusset connectors. The tubular members are interchangeable and adaptable with other tubular members.

Abstract: A hose-pull apparatus for mounting to an irrigation system mobile tower supporting a fluid-carrying conduit. The hose-pull apparatus includes a swivel, a first pipe section, a joint, and a second pipe section. The swivel is configured to be in fluid communication with the conduit and rotate about a vertical axis. The first pipe section has a first end connected to the swivel and a second end extending outwardly from the swivel so that the first pipe section can pivot horizontally. The joint is connected to the second end of the first pipe section. The second pipe section has a first end connected to the joint so that the second pipe section can articulate relative to the first pipe section. The joint also has a second end configured to be in fluid communication with a supply hose.

Abstract: A joint assembly for joining first and second pipes of adjacent elevated spans of an irrigation system, the joint assembly comprising a tower end extension, a pivot end extension, an alignment ring, and an alignment bracket. The tower end extension connects to a tower end of the first pipe. The pivot end extension connects to a pivot end of a second pipe. The alignment ring is connected to the tower end extension and is configured to pivot about a yaw axis. The alignment bracket is connected to the pivot end extension and the alignment ring. The alignment bracket is configured to pivot about a pitch axis relative to the alignment ring and to rotate about a roll axis relative to the pivot end extension.
