C 28 mower

[Harryaroo]

I'm running what I believe is a c28 international 3 pt hitch sickle bar mower behind a ford 9n. Someone gave me this mower and it has taken me a bit to get it working right but actually it mows pretty well. I'm having a problem with the belt however. I have a B48 v belt on it but it always flips over after using it a little. Any solutions for this? Probably I'll wear the belt out pretty quick with it flipped over... Go to a B47, assuming I can get it on there?

A flipping belt often is worn out. Misaligned pulleyscan also cause this,but you would see that if it were that severe.My old Hydroswing would flip the belt when it got worn. It looked ok,but would flip/roll. A new belt fixit. I would replace the belt on your mower.

The belt is rolling over because you have the wrong belt. I have one of these mowers. The belt I run is a C51 and it has a 15/16" top width. It should be almost flush with the outside diameter of the pulley. There are 2 different pully diameters. One high speed and one slow speed. Looking at the parts manual, the fast speed one is the most used. I also show a Goodyear number of 20042183 for the same belt. Let me know if this will work for you. IF it does not, I have a Gates number for it also, but I have to do some more digging.

Rick is correct. I have two C28's and one C32 (the trail version of the same mower) and they use C-section belts.

Mind you, on one of the C28's, back when my grandfather used it the belt still flipped. My grandfather just ran it like that as it still worked (and that one was the beater mower he used for pasture maintenance), but when I got it I aligned the pulleys (drive pulley housing had bad bearings and was misaligned) and it stays where it should be now.

Daniel, thanks for bring the bearing notice up. After I sent the post, I thought I should have brought that up. I ran mine for a couple of years when it showed up that the bearing was in really bad shape. Also, another point to watch is the rachet release on the back of the flywheel. Don't get to carried away with the tension. It is supposed to slip if the sickle gets plug up. Also, Binder Books has a complete set of manuals for this mower. I have the operator and parts book for mine. They have been a big help.
