Louise: I'll try to keep this as short as I can. Possibilites to check are pulley alignment, belt tension, and foreign objects. If you had the wrong pulley it may have caused an alignment problem. If you buy the new one, be sure the "protrusion" faces the right way if you have an assembly drawing. If you don't have a drawing, install the pulley to optimize its alignment with the other pulley(s) with the deck in the mowing position. If it still looks cockeyed you may have a bent spindle or some other warped/broken part (not likely), or an extremely bad bearing (unlikely to be that bad). Be sure the belt is neither too tight (not likely) nor too loose (possible). As for foreign objects, here's what happened to me. It's a long shot but it may apply in your case: A small piece of stick broke off and lodged unnoticed in a groove on one of the pulleys. The next thing I knew, the belt broke (it was about 2 years old). I put on a new belt and it broke within two hours. I traced the problem to the little piece of wood, which was worn smooth and had created a small (maybe 3/16") bump in the pulley groove. Each time the pulley revolved the bump would wiggle the belt just enough that the outside of the belt (where its strength is) rubbed on a belt guide. It didn't take long for the outside of the belt to fray enough for the belt to break. I popped the wood off the pulley with a small screwdriver and have had no problems since. So, check your pulley grooves for stuff that shouldn't be there. If the pulleys you still have are O.K. it may be worth a walk in the weeds to check the one that flew off. Try to avoid finding it the hard way (with the bush hog)! Good luck - - Mark W.

A Cautionary Tale - by Ian Minshull. In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
