DEFINITION

Classification: 172/240

(under the class definition) Apparatus comprising a ground wheel or wheel substitute such as a runner so arranged in the apparatus or so attachable to the apparatus that when the wheel or wheel substitute engages the ground the apparatus may not effectively perform its intended earth working operation but may merely be readily moved.

(1) Note. A wheel or wheel substitute may be stated to be for transport only but if as disclosed it may actually engage the ground in supporting or gauging relation without precluding the operation of the earth working tool it is not classified under this definition. Such devices may be found in subclasses 395+. If the means attaching the wheel or wheel substitute to the implement can only be used to support the implement for transport and in any other position the wheel serves no purpose (e.g., gauging or supporting) classification under this definition results.

(2) Note. The wheel or wheel substitute may constitute a part of the earth working element itself, which functions as a wheel or runner or an earth working element in accordance with different positions in the apparatus.
