A drawbar pin adapter which can allow a smaller drawbar pin to be used with a larger drawbar. A drawbar pin adapter is provided for a tractor drawbar having a lower strap, an upper strap and a drawbar pin bore which extends through the upper and lower straps and which receives a drawbar pin. The adapter includes a cylindrical bushing mountable in the drawbar pin bore in the lower strap and a hollow housing which is mountable over the lower strap. The housing includes a lower plate, an upper plate and left and right side plates. The upper plate has an upper bore formed therein, and the lower plate has a lower bore formed therein. The upper and lower bores have a diameter which is smaller than an outer diameter of the bushing so that the upper and lower plates hold the bushing within the drawbar pin bore in the lower strap. The bushing and the upper and lower bores receive the drawbar pin when it is inserted through the upper and lower straps. A retainer retains the housing to the drawbar when the drawbar pin is removed from the drawbar pin bore. The retainer includes a cable coupled to the housing and looped around a portion of the drawbar.

A suspended drive axle and agricultural tractor having same including a central housing having inboard final drives and left and right axle housing suspended therefrom by upper and lower control arms with axle shafts extending outwardly therefrom to which wheel and tire assemblies are mounted. A constant velocity universal joint is provided between the inboard final drives and the axle shafts. The universal joint having a pair of journal members and a coupling yoke that radially surround the drive and driven yokes of the joint whereby the axial length of the universal joint is minimized to enable the wheels to be located on the axle shafts at 60 inch tread spacing. This allows the drive axle to be used on a row crop tractor without altering the structure of the vehicle from a conventional row crop tractor whereby the characteristics of a row crop tractor are maintained.

Suspended drive axle and agricultural tractor with same

A tractor with a front wheel suspension and mechanical front wheel drive wherein the front wheel drive differential case includes an engine oil sump replacing the need for a separate engine oil sump and wherein the suspension control arms are mounted to the differential case through integrally formed mounting structures in the differential case. These mounting. structures reduce the number of front end components thereby improving the packaging of the suspension, steering and front wheel drive. The elimination of the oil: pan allows the front axle ground clearance to be increased while improving ground visibility in front of the tractor over the hood.

Tractor with front suspension

A steering knuckle and ball joint assembly for a tractor is provided in which the ball stud has a spherical ball portion and a pair of studs extending oppositely therefrom for attachment to the steering knuckle. The double studded ball stud enables the overall size of the ball studs to be reduced compared to a ball stud having a single stud and still accommodate the loads applied to the ball joint by the dual front wheels. Ball joints are used for both steering tie rods and suspension control arms. The steering knuckle is pan shaped to surround the ball joints on all but the interior side of the knuckle where the steering and suspension arms are connected. This shielding of the ball joints protect the ball joints from dirt and debris, especially from the mud and dirt thrown by the front tires.
