OK folks. I too seem to have an HST no start problem, it seems a bit different,though. It won't find neutral. it's either going forward or reverse. Won't start unless i 'hunt' for neutral. seems to be sticking in gear. i've cleaned and lubed the 'rocking' forward/reverse lever and it still seems not to have a neutral. if i let it sit for a long period, it seems to start with no problem, but you can't get off the tractor. am i missing something or does this sound like a safety switch issue. sorry, haven' gotten a service manual yet. that's the next thing on the list.
