Abstract: A multiple mower arrangement for use on a tractor, comprising a principal mower having at least one rotary blade. A power shaft extends approximately the full lateral width of the principal mower, and delivers power to the rotary blades of such mower. A swingarm mower equipped with a rotary blade is hingedly supported by a hollow arm on the outboard end of the principal mower, with the arm being in turn supported by a hollow hinge. A rotary power shaft extends through the arm and hinge, such that rotary power can be effectively transmitted without the use of belts from the power shaft to the blade of the swingarm mower. A bias arrangement normally biases the swingarm mower into an outwardly extending operative position, with such bias being overcome at such time as the swingarm mower contacts a tree, fencepost, or other fixed object, with power being continuously supplied to the blade of the swingarm mower throughout its full range of operating positions.

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.

Abstract: A device in the nature of a rotary tiller equipped for traveling through fields as well as uneven terrain, for effectively chopping up encountered clods, vegetation and debris, and mixing same with the soil. We utilize a framework in which either of two different types of bladed, couner-rotating rotors may be effectively mounted, with one type of rotor having a number of outwardly extending teeth that are adapted for penetrating the ground as the tiller device moves thereover. The outermost portion of each tooth is provided with a novel cutting blade, which may interact with a stationary shear bar, with this type of blade being well adapted for chopping up encountered vegetation and for mixing it thoroughly with the soil.
