Abstract: Animal immobilization apparatus accommodates a typically encountered range of herd animal sizes to permit an unassisted operator to perform various animal treatments such as castration, innoculations, surgery, tatooing, and the like. The apparatus is especially useful to an unassisted operator whose task is to quickly humanely castrate the various sizes of pigs in his herd. Each successively encountered herd animal is placed supinely within the apparatus cradle that is frontally equipped with a canopy restricting the animal's head. A laterally extending restraining-bar is moved forwardly and downwardly along apparatus parallel inclined-rails so as to press forwardly against the thus immobilized animal's upstanding hindlegs. For further operational convenience, the apparatus will have the cradle member pivotably mounted at some finite-elevation, and will be equipped with means for resisting the hindlegs reflexes against the restraining-bar.

Abstract: Disclosed are towably paired teams of farm implements pivotably connected together at their central leadward-tongues to an intervening vehicular frame member which permits a tractor or other drayage vehicle to tow the farm implements together. During abreastly field position, the drayage vehicle tows the frame member from its medially positioned frame-tongue, there being removably secured bracing means, preferably comprising guidably automatically engageable struts and couplers, to maintain the two farm implements in finite-spacing parrallelism.
