SAM58 30 #1 Posted August 17, 2011 Recently I was mowing here at the office on a saturday and my 520H w/ 48" SD deck. We have had lots of rain and I think it has been raining miracle grow. Grass was real thick and wet close to the ground. Needless to say it took out my A-100 mule drive belt. I did not have an extra one but we sell B series belts here at the store and I had some in stock. So I put a B-100 on it to finish the grass and it worked great! I have left it on there and cannot see any problems with the wider belt. The A series is 1/2" wide and the B series is 5/8" wide. It doesn't set as deep in the pulley as the A series but is working fine. Also I notice the the 60" deck that I had came with a B-128 on the deck to drive the spindles, but the mule drive belt is a A-100. Anyone else tried different series belts on theirs? Do you see any problems that it might cause in the future??? :ROTF: Share this post Link to post Share on other sites
tarcoleo 119 #2 Posted August 17, 2011 On my C-series WH's with 48" SD decks, "B" belts are not successful; they are thrown off frequently whereas "A" kevlars are not. These "A"s have been really long lasting. Just my experience. Tom in RI Share this post Link to post Share on other sites
