In one example, a continuous track transport system for an irrigation system is provided that includes a continuous track with multiple track plates arranged so that adjacent plates are directly connected to each other, and also includes a gear train connected with the continuous track and operable to transmit an input torque to the continuous track to effect movement of the continuous track. The gear train includes a drive gear having an interface that is connectible to a gearbox of an irrigation system chassis, first and second driven sprocket-gears engaged with the continuous track, each of first and second driven sprocket-gears including a respective driven gear engaged with the drive gear, and a frame to which one or more gears of the gear train are rotatably mounted. Any one or more of the drive gear, sprocket-gear, and frame may comprise, or consist of, molded, glass-filled nylon.

A crawler mechanism includes a frame, a track including a plurality of shoes coupled together and supported for movement relative to the frame along a direction of travel, a sprocket, and a guide rail. The frame includes a first end, a second end, a first side extending between the first end and the second end and proximate a support surface, and a second side. Each shoe includes an intermediate portion having a first hardness. The sprocket drives the plurality of shoes to move along the second side of the frame. The guide rail is coupled to the second side of the frame and includes a base having an outer surface and a coating bonded to the outer surface. The coating contacts the intermediate portion of the shoes as the shoes move along the second side of the frame, and the coating defines a second hardness less than the first hardness.

A frame assembly for a machine is disclosed. The frame assembly includes a main frame including a pair of spaced apart members extending longitudinally between the front and back of the machine and a front frame. The front frame includes a top plate having a first portion extending between the spaced apart members and a bottom plate coupled to the top plate. The bottom plate has a second portion extending between the spaced apart members. The front frame is connected to the main frame by attaching at least a portion of the first portion and at least a portion of the second portion to the spaced apart members.
