HeadExam 1,783 #1 Posted October 25, 2015 I got a new tractor today. Its an Allis Chalmers, but it wasn't built by Simplicity. It features a engine that debuted the year of its inception. Anyone want to make a guess as to what it is? Share this post Link to post Share on other sites

HeadExam 1,783 #3 Posted October 25, 2015 Okay, its not a Gilson. It is a Allis, a real Allis Chambers made by Allis Chambers. Its a 1974 416 Hydro, Hmm I have some these already, but what the hay. It came with an extra block and bevel gear box, and all the original manuals and paper work from 1974. Allis ordered a certain number of the new K341 engines from kohler in late 1973 to put in the 400 series tractor, but a problem arose when Allis found out that a monopoly lawsuit against them was being overturned and they would be allowed to have Simplicity build their Outdoor Power equipment again. The problem was they had decided to make a 410, 414, and 416, but with the suit settled they would not need the 16hp Allis 400 spec'd engines. The 10hp K301 and 14hp weren't a problem in not accepting for delivery, Kohler could move these engines to another brand, but the new 16hp K341 was a new model engine and Allis had made a commitment to buy a certain number of these and could not retract. Allis decided to put more 16hp engines in what would have been 14hp 414 Hydros. That is why you only see Allis 414 shuttle shifts, not hydros the hydros were changed to 16hp and 416 model to use up the engines due to the plant closing and the 400 series model ending the same year it started. 3 WestwoodGazelle, Triumph66 and Joe the small engine man reacted to this Share this post Link to post Share on other sites

HeadExam 1,783 #5 Posted October 25, 2015 I already have a 416H Hydro and 416S shuttle shift, both with electric lifts and clutches. The shuttle shift is basically a four speed hydro. I have a snow blower, tiller snow plow, cultivators, harrow, and mid mount grader blade, as well as three decks, so this and the extra standard block and bevel gear box will come in handy 4 Triumph66, WestwoodGazelle, nigel and 1 other reacted to this Share this post Link to post Share on other sites
HeadExam 1,783 #6 Posted October 26, 2015 1975 and earlier hydro static transmissions for brands like Ariens, Allis, Homelite, Gilson, and Simplicity were Vickers T66 models like the ones below. After 1975 those brands switched to Sunstrand hydro static transmissions. Bolens used Eaton and later switched to Sunstrand, while Cub Cadet was Sunstrand all along. The cast iron Vickers Hydros were nearly 50 pounds heavier than the Sunstrand models. 1 Joe the small engine man reacted to this Share this post Link to post Share on other sites
