1450 Question
 

Why does my older hydro loose ground speed when tackling a hill or grade? Why doesn't it stay the same? :bigthink: Is this a problem with my tractor?

This question is age old. This is normal. It is a hydrostatic transmission, not an automatic. It will lose some speed on hills, you just have to get used to it. Not saying that it can't be improved somewhat, depending on how bad it is. But, unless your losing a lot of power (I.E. you have to move the speed lever to almost max) it is normal.

Trunnion could also have excessive wear causing that problem.

This is true :ThumbsUp:

I don't mean to jump in on someone else's thread but I'm about to do some trunion work on my 127 want to know if there's a good resource with good pictures on how everything is supposed to go together or adjust or work. I know I can get parts break-downs from parts tree or CCParts but I'm hoping for something more...colorful and visual. I know a worn trunion can effect ground speed so maybe it's something the OP can check on his, too :bigthink:

There isn't that many pieces to it. Take pics before you start. Its really not difficult.

In the Technical library there is a thread on repairing the trunnion.

I have the same problem with my 1450, did the repair and improved the problem 100%. My property has hills all around my 3.5 acres and today I was hauling a 50 gal drum full of water and when pulling the hills I still had to adjust the lever a little to maintain constant speed, not much, maybe an 1/8" to 1/4" or so up or down. I'm happy with it and it's worth doing the repair on the trunnion/linkage.

If you have or suspect that you have trunnion problems with your Cub Cadet hydro, start by going here.

There is a lot of good debate here.

After you have fixed your trunnion your forward-reverse lever and foot pedal may be out of wack, so go here.

Personally, I see no need to add extra metal pieces to the square hole, unless the ends are worn crooked. I have never had this problem with any that I have fixed. So I simply weld the slots in the corners and then file them back square again, then shim my damper plate. I also like to pull the rear end and hydro out to make the repairs, while it's out I can pressure wash it, I believe they run much cooler when clean.

Hello. Does anyone have any specs on the springs? What is the new length and how much pressure is required to compress to some specified length?

Where can I find said trunnion? And a picture of for a comparison?
