Found this in the history.Simplicity tractors continued to be built in Port Washington, but for the first time there were differences besides paint and decals. In 1971, the 300 series introduced many design changes. The body was painted orange and the hoods painted cream, and Kohler engines were used for the first time. In 1973 the similar 400 series was introduced. These tractors bore little resemblance to the Port Washington built Simplicity models. The mower decks and many of the attachments were different. Also in 1971, the B-207 and B-208 were updated to the new paint scheme, but retained Briggs power. The 206, 207, and 208 were continued as the Homesteader series from 1972 to 1974. Also in 1972, Allis-Chalmers introduced the model 616, which was the Simplicity PowrMax with orange paint and a different hood. The 616 became the 620 in 1973 with the new 20 horsepower engine. In 1975 the 620 was relabeled as the 720 to match the numbering of the updated smaller tractors. To the best of our knowledge the 620 and 720 models are identical except that the later 720’s had an upgraded front axle. AC later came out with a second model 616, which was a painted over Simplicity 4216 and had no relation to the earlier “PowrMax” 616.

During 1965, Allis-Chalmers purchased Simplicity. The federal government challenged the purchase. Due to the fair trade laws in effect at that time, the government claimed that Allis-Chalmers controlled too great a share of the market and thus limited competition. As a result, in 1967, Allis-Chalmers opened a new plant in Lexington, South Carolina to build garden tractors. The first models built there were the B-207, B-110, B-112 and HB-112. The B-208, B-210, B-212, and HB-212 were introduced in 1970.
