4-WD Tractor Built From Two Farmall Rear Ends

“It rides on narrow tires and has high clearance. Works great to spray corn and potato crops,” says William Davis, who built an articulated 4-WD tractor out of two 1950’s vintage Farmall C rear ends and a 45 hp. diesel engine from a Ford 3000 tractor.

“It took 3 years to build. The first year I got the two rear ends set up, the second year I installed the engine, and the third year I built the sprayer,” says Davis.

The 2 Farmall rear ends face each other and are connected by a shaft that is held in place by a pair of bearings. To marry the two rear ends, the Masontown, W. Va., farmer first built a hinged frame to hold the 2 units
together. He then ran a driveshaft from the original pto on the front rear end to the back rear end, using a home-built articulated joint to provide articulation. It consists of 2 big bearings that support 1 1/4-in. dia. bolts. A pair of hydraulic cylinders that act on 2 attached channel irons are used to steer.

He powered the machine with a 40 hp. diesel engine out of a junked Ford 3000 tractor, which also provided the tractor’s hydraulic and steering systems. He also made a bell housing to fit the Ford engine to the IH tractor. He covered the engine with the junked hood off a Farmall C.
Both rear ends have separate transmissions
and gearshift levers, which are connected. The pto on the front transmission drives the rear transmission and rear pto.

He used 1 1/4-in. aluminum angle iron to build the 30-ft., 5-section spray boom. The booms are raised and lowered by a pair of 2,500-lb. ATV winches powered by the tractor’s electrical system. The spray tank can hold 200 gal., and there is a smaller separate tank for direct injection of chemicals. A pair of spring-loaded electric screw jacks assist in raising and lowering the boom, which has a spring-loaded breakaway system.
“It has plenty of power,” says Davis. “I already had one of the tractors and bought
the other one for $300. “The tractor has both front and rear
brakes. A hydraulic cylinder, operated by a master cylinder on the front rear end, is used to operate the brakes on the back rear end,” says Davis.
“I spent about $7,000 to build it and used only high quality parts because I wanted to do the job right.”
