In 1968 the John Deere 140 had a 12hp K301AS. For 1969, the 140 received a 15% upgrade in power with a move to the 14 horsepower Kohler cast iron K321AS. Also new for the '69 model was individual rear brakes. These allowed sharper turns, as well as the ability to feather a wheel if it was spinning. A change a little more difficult to detect was a switch to a true three spool valve on the H3 models. At Serial number 30001, for the 1971 model year a change was made in the type of hydrostatic unit used. This change incorporated a pinion and ring gear design rather than the bull gears used on previous models. The rear axle diameter was also increased. Rear brakes were changed for the disc type used up to this time to a more reliable drum brake system. Individual rear wheel brakes were retained on the H3 models. Other changes were made throughout the run from the 1968 through 1974 model years. Additional John Deere attachments were added such as the 54C center mounted grader blade and the 542 front mounted PTO.
