Today I was doing some lawn work and after edging, etc was pretty sweaty so I placed a towel over seat and started up mower got 90% of the cutting done on 1 acre when all of the sudden I started getting whipped on my shoulders and mower started bogging, then died, at first I thought I might have run over something but after looking discovered towel had caught on pulley behind seat that drives hydraulics and ripped belt off, of course it is shot and so is towel and I noticed the seat fabric "top of seat" was almost worn all the way through due to towel being pulled out from under me and side seam was torn a little. I could hardly get seat base to tilt forward as towel was jammed in so tight.. I am so glad it was me instead of my wife as she would have been hysterical. I have put a call in Tony at Gizmow to see if they have belt in stock or can tell me where to get one locally. Just be careful as shaft with drive pulley comes out of front of engine right behind seat, my old mower drives from bottom, I have placed towel over seat back for years, I won't do it again.. I am sure there are other mowers that this could happen to also.
