i have a 05 mini z 19/44. after 5 hours on it last year i had the spring that keeps the pulleys tight on the drive belt come off. thought it was a fluke and maybe it was. that was last year. now i have 14 hours on it and tonight i was mowing on a clean up and again the mower stops. nothing from the rear wheels. so i get off thinking its that spring again, but not this time. this time the entire belt is off and laying on the ground. i looked at the belt and it is frayed in spots. now granted i was mowing where there were sticks and things, but this is getting a little rediculus. i have a mower with 14 hours on it and it has been down twice now. of course i will call the dealer, and hopefully they will come fix it there since it is sitting on a hill. just had to vent. pj, any thoughts?
