Has anybody else seen this problem? The side pulleys on the new BX 1860/2360/2660/25 midmount mowers come loose and destroy themselves. The four small bolts- size 13mm head- should be checked to be sure they are tight. I have seen a couple of these come loose and you end up having to replace the pulley. Not a big job, but def. a pain to someone who has less than 50 hours on there brand new tractor.
