Well, nothing major yet,but I had a seal go out on my mid mower leaking fluid. Removed the mower deck, tried a repair that didnt help and then just got mad an went to till up garden for fall planting. Oh, did I mention that I failed to remove the rear half of the driveshaft for the mid mower? Well I did. Really wouldn't have been a big deal except i compounded the error by leaving the PTO lever to mid and turning it on....... Noise and busted ujoint. Oh, it isn't std ujoint. Matches a 1978 Toyota, which almost no one makes any more. But I found one and replaced seal also
