(under subclass 35) Apparatus comprising a motor or motor actuated means for traversing a driven earth working element over the ground.
(1) Note. Self-propelled or tractor-propelled implements are common in this art. Hence for a patent to be classified under this definition, the propulsion means must be recited in some detail, and the mere recitation of a motor is not enough. However, a broad reference to a wheel substitute such as a tracklaying means on a tractor is sufficient. Also a recitation of a relationship with a propulsion means such as the statement that an implement hitch arm is connected to a differential housing (as distinct from merely a "rear axle housing") is enough.
