Tractor Info


Offered in gasoline, propane, or diesel styles, the 656 delivered approximately 66 PTO horsepower. In addition to a regular five-speed transmis­ sion, the 656 was also available with hydrostatic drive, first offered in 1967. This gave an infinite speed range at full engine speed and full power. The gear-drive model featured Harvester’s new Dyna-Life clutch for better performance and longer life. With the same four-plow capacity as regular 656 Farmall tractors, the Farmall 656 high-clearance models gave an extra 12 inches of clearance for safe work in delicate crops. For extra support of the front axles, special braces were added back to the frame. A luxurious, padded seat was standard equipment, and a new grille design was featured.
