    摘要： A vehicle main frame having a longitudinal axis is subjected to relatively high loads in a pair of spaced essentially vertical planes disposed substantially parallel to the longitudinal axis and is supported by ground-engaging driving members through driving-member pivot bearings. The vehicle main frame includes a housing having an axis oriented transversely of the longitudinal axis of the frame and opposite ends. A pair of elongated sidewalls of the frame are disposed in laterally spaced substantially parallel relation which are individually rigidly secured in embracing relation to the opposite ends of the housing and have portions radially outwardly extended therefrom within the vertical planes for accommodating the high loads, the sidewalls being associated directly with the driving-member pivot bearings for substantially directly transmitting the high loads to the ground-engaging driving members in generally loadbypassing relation to the housing to minimize distortion of the housing.

    摘要： A tractor has a bulldozer assembly pivotally fitted thereto. A cylinder extends upwardly from the bulldozer assembly, and second and third cylinders extend upwardly from a forwardly extending frame portion of the tractor. A yoke interconnects the upper ends of the three cylinders adjacent the nose portion of the tractor. Restraining bell cranks interconnect the nose portion and the yoke. The cylinders are substantially vertically disposed, so that vertical loads on the bulldozer assembly are carried substantially fully by the first cylinder, and transferred through the yoke to the second and third cylinders to the forwardly extending frame portion, with minimal loading being carried by the restraining bell cranks.

    摘要： A dozer for a farm tractor which includes a blade pivotally mounted at one end to one leg of a substantially U-shaped blade frame, and an extension arm selectively interconnected pivotally between the other blade end and the other leg of the blade frame to pivot and angularly dispose the blade toward one side of the tractor. The extension arm is selectively located in a reserve position between the blade and blade frame when the arm is not in use and when the said other blade end is attached to the said other leg. The extension arm is pivotally attached at one of a pair of longitudinally spaced, front and rear connection points, and the said other blade end and said other leg are attached at the other connection point when the extension arm is selectively pivoted behind the blade in the reserve position. A bearing means, pivotally connecting the bight of the blade frame to the chassis frame, includes a journal carried by a support plate at each side of the chassis frame, the journals pivotally mounting the bight. Pivot means mounts one journal to its associated support plate about a pivot axis, while means movably mount the other journal to its support plate, whereby the blade can tilt about the pivot axis of said one journal.

    摘要： This invention pertains to a tractor blade attachment apparatus comprising a frame pivotally secured on one end to the pivot holes of the conventional hitch assembly disposed on the rear of the frame of a tractor and with the front end of the frame disposed in front of the forward end of the tractor, wherein the front end of the frame is adapted to hold a blade or the like. Pivotally secured between the front end of the frame and the front end of the tractor is a hydraulic mechanism for only raising and lowering the blade. The frame includes a V-shaped element, which in conjunction with the longitudinal members of the frame transfers the stresses, caused during the operation of the blade, to the hitch assembly of the tractor. The frame of hollow beam construction contains the hydraulic lines which are fluidly interconnected between the tractor hydraulic control system and the hydraulic mechanism. Skid members are adjustably mounted on the frame members for positioning the blade relative to the ground and adjustable members are interconnected between the blade and frame for varying the pitch of the blade.
