Might be, JD...but I think it's a technique problem (stomp down on the pedal)...let's see how he does with a little less pressure (and maybe a lower range selection).
That's a low range slope. If you have three ranges (can't recall, but I think the 955 does), you might try the middle range ("B"?). Just don't flatten out the foward pedal...

No...about 3-4 hours east outside York (south central).
Hope that lower range and less pressure on the pedal works for you. Gotta admit, less pressure on the pedal when you want more power is counter-intuitive. Guess that's why I prefer gears...

That's because you are thinking of it as a accelerator pedal, which it is not. One must think of it as a "infinitely adjustable gear shift" so less pedal is a lower gear.
Clear as mud?

kennyd...yes, I was definitely making that mistake. I guess I was figuring it was like a car...push the accelerator down harder as you go up a hill.

Listen to kennyd. The harder you press the pedal, the more fluid volume you are asking the pump to send to the hydraulic motor but what you really need is less volume and more pressure (pushes harder). The net result of your action is the exact opposite of the requirement. This is the nature of HST and you need to learn to operate it for what it is...NOT AN AUTOMATIC TRANSMISSION like a car, and what you are pushing is not an accelerator. You have nothing wrong with you tractor IMHO but a bit wrong with technique. If the engine rpm's are dropping, back off on the pedal. If you are in H range and you continue dropping rpm and speed, you may need to select L and use the same technique. Push as hard as you want but when you start losing rpm, back off. The faster you stop trying to operate it as a car the faster you will learn how to make your tractor work for you. Good luck, have fun, and enjoy.

I had a 955 and used it to mow steep hilly fields all the time, and never had problems with climbing while dragging a 272 rear finish mower. I loved that tractor and wish I'd have kept it.
You have an issue -- don't know what's going on, but you shouldn't have the unit lose power when you push on the pedal.

I think KubieTwo and Kenny d are exactly right.
My 855 runs excellent. Well maintained. Lots of power. But if I try going up a steep hill in high gear at a fast speed, the engine speed drops down and I have to back off the HST pedal to keep the engine from lugging. It has been acting the same way for 3 years (since I've owned it), with no worsening of this "problem". It is not a problem, just the way it is. You can't ask a 24 hp tractor to go up a steep hill at a high rate of speed without bogging the engine down. You will be fine.

Well, it looks like you guys were right. I checked the hydro fluid over the weekend and it was full. So I took the hill again. This time, I just pushed the pedal down a little bit and the tractor chugged up the hill. The engine RPMs never dropped, it just slowly climbed up the hill. Next time I'll have to try pushing the pedal just a little bit further.
Although, I did find out that my fuel gauge doesn't work. Don't ask me how I found that out. I was also very happy to find that the previous owner/dealer painted the engine and painted the fuel bleed screws in place. I'm going to have to figure out how to break those suckers loose.
Thanks again for all the help. I have a feeling that I'll be spending a lot of time trolling this site.
