Just joined as I too have a broadmoor that struggles to pull (and makes a din), local dealer said tranny is stuffed, not worth buying a new one but he will look to see if he has a second hand one. I thought the belt was slipping but this guy says over 500hrs they tend to let go. I have found service kits and I am keen as the rest of the machine is great, shame to scrap it. So, has anyone serviced their hydrostatic drive (simplicity says sealed for life and only serviceable by them!) yeh right.
