.~.~> With vertically adjustable ground support {1}
DEFINITION
Classification: 172/326
(under subclass 324) Apparatus in which the draft means is moved vertically with respect to the framework.
(1) Note. In those devices in which the hitch means has a very minor vertical movement due to its manner of support on the frame but accomplishes its function due to a horizontal component of motion, classification is not under this definition. Such devices may be found in subclasses 588 and 605.
