Patent abstract

Mobile towers of an irrigation system have drive wheel assemblies that propel the towers along the ground. At least certain of the wheel assemblies may comprise dual wheels that share a common axis of rotation but are separately driven by their own drive motor. By driving the two separate wheels in unison but with their own individual drive shafts, increased ground-engaging surface area can be obtained without a consequential increase in load for any one motor.
