I bought my ExMark Phazer back in March and I had to put it in the shop this week. The deck belt came off several times and the mower started making a rattling noise while running. Eventually the pulley that is connected to the engine and drives the deck came off with the belt and just fell on the ground. I remounted it, but the bolt will not fully tighten like it is stripped. It still rattles. I worked on it for a couple of hours, but had to give it up and just take it to my dealer. Just wondering if anyone else is having this problem or has any suggestions.
