 TC45D wont move when hot

Hello, this is my first post to this forum. Let me first say thanks for the info on other topics that I have receied by just reading other postings. On to the problem. I have a TC45D that runs and drives fine until about an hour into it. It just stops moving like the pumps are not pumping any more or a tranny that slips when hot. It gets slower and slower until it just wont go. Any ideas of where to start looking?

Thank you

Hello, welcome to tractorpoint!

Are you sure it's heat related?

There may be sediment in the fuel tank. When the tractor sits for awhile the sediment settles to the bottom of the tank. Driving around causes sloshing that mixes sediment in with the fuel, suction from the fuel pick-up draws it in and eventually the pick-up plugs. Turn the tractor off for awhile and all the sediment settles again. Lather, rinse, repeat.

Thanks for the reply. At this point, I will try anything. the reason I suspected heat related was because the tractor "runs" fine, it just doesnt move after 45min or so. I havnt messed with this type setup at all, most of my work on tractors has been old JD stuff. Thanks again for the feedback.

The sediment in the fuel theory is probably wrong if the engine doesn't struggle or stall when hot.

It just stops moving? Any weird noises?

I take it this is a hydro transmission?

Cover the rad, start it, and see if there's a problem after 10-15' when it's hot -- but not stirred up or been working for an hour.

The hydraulic fluid level is at the correct level, right?

Have you checked the temperature of the hydraulic fluid? Is it actually hotter than it should be, or is it just presumed to be hot after an hour of working?

I've heard of some hydrostat systems that incorporate a heat sensor activated shut-down to prevent damaging the system if it runs low or just gets too hot. If that's the case and the rad was clogged with debris for instance, it could cause a heat related safety to kick in.

Best of luck.

Thanks for the suggestions. The fluid level is ok, no weird noises, just slows down and then finally stops. Let it sit for 30-45 min, runs fine for another 45 min to an hour. I will check the cooler again (looked clear)and also see if there is some sort of temp sensor system on it. i dont have a manual for it which isnt helping any. I called the dealer and they said they have never heard of such a thing. Just my luck!!! Let me know if any of you have any other ideas.

Thanks again

Could be the chrage pump is on its wa out if heat is causing it to degrade. Wrong oil will cause areation leading to overheating and degradation.

Are the tires' pressure within spec? Driveline bindup may be taxing the driveline if so.

I wonder if the brakes could be dragging to the point they heat and swell up--45 minutes is nothing in the scheme of things to have a large machine like that cool down.

Too high of gear range will tax the system and cause premature heat buildup too.

The drive line if it's like my TC33D which is similar but not identical to yours has a relief valve--yours may be weak.

Plugged hydrostat filter(s)?

Ummm, "chrage pump"? "wa out"? "areation"?

Has the fluid and filter(s) for the transmission been changed recently? If so was it working fine before?

Is it way past due to fluid and/or filter change?

Following up on couple of EW, be sure the brakes are not set and try using lower range.
