I also have a TC33D with the infamous "click and won't start" problem. It was intermittent, and the thing was driving me nuts. The dealer checked out the machine and couldn't reproduce the problem (I think they should have made more of an effort, and at least check all of the relevant connections -- that's not too much to ask, is it?). And then of course as soon as I got it back, it started acting up again. I decided to check the fuses, and when I got to the main fuse, I saw that there was no way for me to access it. It's blocked off from below, and too far down to access it from above. The most I could do was barely touch it and give it a good jiggle. And wouldn't you know it, the tractor's been starting without a problem ever since! But I would really like to check that main fuse more carefully -- must be a loose or bad connection someplace -- but how the heck are you supposed to access it? Does anyone have any suggestions?
