some people try to use the cheap hoses from hardware stores. They wont melt, but they end up cracking or falling off. You shouldnt uuse the cheap hoses. Only use the hoses that are ment for radiator lines.
I had that happen to me. There was no damage though. I was running 18 inch turf tamers and I was in 2nd wide open and the frame cought on a little stump and I almost went over the bars.
