DEFINITION

Classification: 56/10.8

(under subclass 10.1) Machine provided with means for connecting or disconnecting or regulating the action of one or more mechanisms of the harvester or the vehicle relative to its motor, at the will of an operator.

(1) Note. The term "mechanism" includes (a) those parts of an operating assemblage that move relative to one another or to their supporting structure for the purpose of performing a harvesting function, (b) those parts of a harvester-supporting structure that move relative to the harvester or its vehicle for the purpose of adjusting the structure relative to the harvester or its vehicle, and (c) those parts of a vehicle that move relative to the vehicle or the ground for the purpose of transiting the vehicle over the ground.

(2) Note. In this and indented subclasses a foot-actuated pedal is considered to be as "manual" as a hand-actuated lever.
