Abstract: An upper link storage clip for securely maintaining the upper link of a tractor three-point hitch in its storage position without side to side movement, the storage clip being so designed that the upper link can be readily placed within it by a one hand operation. The upper link storage clip utilizes a spring biased pivoted hook to maintain the upper link between a pair of rearwardly extending spaced apart arms when the upper link is in its storage position. The rearward surface of the pivoted hook is provided with a cam surface so that as the upper link is forwardly swung towards its storage position the pivoted hook will be cammed to an open position permitting the introduction of the upper link between the pair of arms, the spring causing the pivoted hook to swing to its closed operative position when the upper link attains its storage position.

Abstract: A roof construction for a tractor cab or the like wherein the roof of the cab is provided with an opening normally closed by a removable panel which is secured in place by opposed retaining means in such a manner that the peripheral portion of the removable panel overlies the border about the opening in the roof. The retaining means are of a generally simplified construction and are so designed that when they are in their normal operating position the peripheral portion of the removable panel is held in secure sealing engagement with the border about the opening, the retaining means also being easily moved towards each other to a release position wherein the panel can be readily removed from the opening.

Abstract: A grille mounting apparatus operable to support a grille on a tractor grille frame assembly for swinging movement between a service position wherein the grille is disposed to one side of the tractor grille frame assembly and a normal operating position wherein the grille is disposed in juxtapositioned relationship with respect to an inwardly extending flange of the tractor grille frame assembly. Improved fastening means are utilized to maintain the grille in its normal operating position, which fastening means may be released without the use of tools to permit the grille to be moved to its service position.
