New Holland TN75
We have a New Holland TN75 tractor that is either a 1997 or 1998 . There is a yellow warning light that sometimes comes on when going up a hill. It is a blinking light and just started yesterday. It is a circle with an exclamation point inside with parathesis on the outside of the circle. Can you tell us what this light is for. We lost our manual in a fire in 2023. We just had a new clutch put in this tractor this past summer.

I wonder if your DPF is getting plugged and only comes on during harder work like going up a hill. Not much info on line to look at.

What i see is showing brake system failure. Weird, why when going up hill

No DPF on this tractor. Too old.

The symbol is for the brake fluid reservoir indicating that the fluid is low. It is probably on the cusp and going up/down a hill is causing it to flash.
Use NH brake oil, NOT brake fluid.

Interesting...I learned something today. Another thread on this fluid:

Strange…i never really thought about tractors having brake cylinders, i always just thought they used gearing in transmission for brakes, and that just used transmission fluid. Never really gave it any thought

There's a long thread about a guy replacing his master cylinders (yes, 2 of them) in here.

No DEF on these tractors. Thankfully. Computerized, but only mechanical fuel injection.

NH are a pain. Have a TD95D. Brake fluid. Power steering reservoir. Expensive filters. Makes me glad I have more JD than NH's
