The U series had the hand clutch and the UB series that followed had the foot clutch. My U also lad the live PTO setup off a UB on it and that was a hand clutch as well. The U was built with shoe brakes and the UB was disk breaks and putting the LPTO on my U made the left brake that the disk brake you could not get enough pressure to make that brake work.Minr also had a LP head on but was a gas burner so it had in mid 50's on HP on dyno. Also the drawbar was not adjustable in height and when we went to hook up the baler the pickup would not drop to less that 3-4 inches above the ground on the wheel that controled the pickup height. A Z was same on hand clutch while the ZB whent to foot clutch. The R I think was only hand clutch for the entire production, I never saw one with a foot clutch. The big difference between the U and UB and the Z and ZB was the hand to foot clutch and a higher seat seat setup instead of the low seat of the U and Z where you straddled the PTO shaft. I only had mine for a couple of months back in 68 as it was just too hard to handle. That extra high drawbar could not keep fron end on ground in tough plowing. Traded it off and a person without a left foot bought it because of that hand clutch and from what I heard he was happy with it. I suppose he found a way to lower that drawbar to a workable height. Never was around the bigger tractors like the G series so don't know anything about them Mine was supposed to be a 44 model and it had the single block engine.

Today's Featured Article - An AC Model M Crawler - by Anthony West. Neil Atkins is a man in his late thirties, a mild and patient character who talks fondly of his farming heritage. He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
