I hooked up the pulley on the JD 40S. My plan is to crush some corn cobs with a JD hammer mill and to grind some shelled corn with a New Holland No. 10 feed mill.I have never operated the belt pulley and would appreciate some pointers.I see some pictures with the belt twisted and others with no twist. The belt I will use is 10 ft. long.
Thank you for your imput.

Tom

He's right, the twist serves 2 purposes. First of all to get the machine spinning the right direction. Second,it does help keep it centered. With such a short belt you would have to really pull on it to get traction. By pull, I mean pull till the wheels did down 6 inches or so, then lock brakes. Have to have a good "eye" to get it lined up. The longer the belt the more forgiving it is on allignment. Eg: 2 inches out of line at 20 feet is less critical than at 10 feet. The weight of a longer belt helps and the sag ot drop of a longer belt gives a little more "wrap" around the pulleys. In my younger years I have seen 50 foot belt almost touch the ground, yet never slip or fly off. We always tried to run with a twist, sometimes moved the tractor to other side of the blower etc to get the opposite rotation. Hope this helps.

From reading past posts on the subject, it is my impression that the twist in the belt serves two functions. One, it reverses the direction of rotation, and two, it tends to keep the belt centered on the pulley.

Proper tension is attained by backing the tractor into the belt. Last time I saw a belt in operation was probably 40 years ago, on a silage blower, and I seem to recall there being quite a lot of sag in the belt. The weight of the belt and the surface of the belt and pulley is what provides the drive, not having it pulled tight like a fanbelt. Belt dressing can improve the "traction" as well.

There, now you know everything I know about belt work. Not very impressive, is it? ":^)

Twisting the belt also keeps the belt on the pulley in high winds. If the pulley is already running the right direction- twist the belt twice, rather than run without a twist if it's a long belt. Short belts like you mention- wouldn't worry about it, but long thresher belts need the twist.
