Thanks guys for you assistance in finding the source of no heat in my TN75D. Before winter I had checked and filled the radiator so I never thought of that. I checked all the cables, etc that were suggested and all seemed well. On a whim, I removed the radiator cap. Nothing to be seen!!

I refilled the radiator with a full gallon :eek: of 50/50 mix and low and behold I had heat. I guess it's been so cold that the engine never overheated even with so little fluid in it. I snooped aroudn to see if I could locate the source of fluid loss but could find nothing other than a few drips under the radiator (not to jump ahead too far, but that turned out to just be a little spilled when filling the radiator).

That day I did not find the leak. The oil was fine and the tractor ran fine with cab heat finally.

I did notice a steady stream of small drips that were where I had driven, but stopped every time I got out to look for the source.

Too cold to look more. Next time I plowed, I refilled radiator, only 1/2 gallon overflowed this time. Again heat fine.

This time I found the leak when I saw fluid driping off left side door step. Earlier I had only seen a few drops and wrote it off as just melted snow. I've never mentioned it but thiefs tried to break into cab and smashed lower window on cab to get in. I think the shards of glass somehow cut heater hose in cab column.

Now all I need to do is figure out how to get to hose to repair it. Suggestions please.

I also still haven't replaced glass even though I have purchased a new one from Messicks. Getting the old one unglued is no picnic.

BTW, I feel rather stupid for not noticing the real problem earlier.

Any ideas on how much I have to take apart to get at these hoses or wahat ever else leaks.

You are likely to have to remove both the headliner and roof top panel. Not at all an easy job due to the design of the overhead components. Any possibility of cutting/splicing the leaking hose?

Probably if I can find it. All I see so far is a drip. :(
