New Holland TC30 Hydrostatic Transmission Making Noiise

[justin2988]

I was pulling a trailer behind my New Holland TC30 this morning, very heavy load going thru mud, tractor was having a heck of a time with it and I pushed it too hard. Transmission started making noise and I could smell a hot/burning smell, unhooked the trailer but tractor is now making a hissing/squealing noise when I accelerate over 5 mph in forward or reverse. It still seems to have normal forward/reverse power but the hissing/squeal is very concerning. Did I burn up the transmission? Any advice?

If it has the HST transmission I would start by changing the fluid and filter.

I've read this suggestion in a couple of other places regarding these hydrostatic transmissions. Could you explain why this is recommended? Is the idea that the oil got hot and lost it's lubricating ability or something?

You can overheat the oil and "burn" it so it loses lubricating properties. Hydraulic fluid should be clear. Pull the dipstick and check, it may smell burnt or have turned black. Even if it doesn't smell I would change it as you stated you pushed it too hard.
