ABSTRACT:
Transport carrier apparatus and techniques are described for transporting repair items to and from an agricultural pivot sprinkler device of the type used to irrigate row crops. The apparatus is self-propelled and includes: (a) a frame having an open front to receive repair items, (b) support area at the front of the frame to support the repair items being transported, (c) at least four wheels attached to the frame to support it above the ground, (d) a power source (e.g., a gasoline engine) for driving the wheels, and (e) handles on the rear portion of the frame for steering the apparatus. The transport apparatus is sufficiently narrow to enable it to travel between adjacent rows of growing row crops so that replacement wheels, gear boxes, etc. can be transported to and from a tower of the sprinkler system without trampling the crops. In a preferred embodiment the apparatus includes a transmission having forward and reverse gears.
