Abstract
A quick disconnect arrangement for use on a tractor or other such farm or grove vehicle principally involving the use of an elongate structural member having an essentially straight mid portion, with this member being removably supported from the tractor at its front and rear ends. This elongate structural member is supported outboard of the adjacent driving wheel of the tractor, and its mid portion is utilized for the support of a rotary implement such as a cultivator or mower, or alternatively for other implements, such as a banker or a de-banker. Advantageously, the front and rear support members are in effect quick disconnect means such that the operator can in a period of a few minutes entirely free the tractor from the elongate support member as well as the implement carried thereby, thus enabling the tractor to be used for an entirely different purpose. Thereafter, also in a matter of a comparatively few minutes, the elongate member can be reinstalled such that the implement is promptly ready for reuse.
