DEFINITION

Classification: 172/98

(under subclass 35) Apparatus in which a movably supported earth working element which is driven in a given path or orbit is provided with an actuating or manipulating means whereby during operation said element may be shifted at the will of an operator to positions in which said path or orbit is spaced from its initial position transversely of the line of travel of the element across the ground.

(1) Note. The usual purpose of the lateral shifting is to follow a crooked row of plants or to chop or avoid cutting out certain plants in a row.

(2) Note. The lateral shifting means may be a handle or foot lever type attendant operated actuating means which may be selectively moved from one latched position to another, or a handle or foot lever type attendant operated manipulating means which may be moved from one position and held in the position to which it is moved by continued application of force on the manipulating means by the attendant.
