i have been thinking these belt things seem to be the cause of a lot of distress. So given there are only a few rotovators. And belts come numbered in length and section it should be easy to build a data base of suitable belts for the range of machines we use. All we have to do is add the numbers on the belt and the machine it fits to this thread. Ie Honda f 400 = A27V. Then we can go to a belt supplier and get what we need. Easy. One supplier is Brammer UK Ltd (old BSL). This is where i get all my belts.
