Anyone have a toro z master that bags 95% of the time? Do you blow through the belt that drives the blower vac? We go though about 2-6 belts a week per machine. We power wash that blower and tubes regularly and still break them. I found that cog belts last twice as long but still break. Personally, I think Toro can and should have built something better. I have even gone as far as changing pulley sizes (with Toro's permission) but still no luck. If it wasnt for the belts breaking so often, I would have said that this vaccum system is better that the old lesco peco system. Anyone have ideas/suggestions?
