So I bought a used 1120D, runs great but it's very slow. The accelerator cable was replaced by a kubota dealer, but it barely moves the throttle. I played with it all day today and finally decide to buy a new one. That's when I discovered the Original part was discontinued and replaced. I think the new part is simply two long. I've adjusted it for all I can and I simply can't get the RPMs up. I can grab the throttle on the engine and double the rpm I can get from the gas pedal.
Has anybody else installed the NEW accelerator cable and had this problem? Any Suggestions?
 
Hopefully Arthuritus will weigh in, but it sounds like you need to go through the process of "timing" your accelerator pedal with your hydro. There is a very precise way to do it and it makes a ton of difference. You could do a search using his name to find it. I printed his procedure and added it to my workshop manual.
 
I saw that thread, but I don't think that's the primary problem. When you push the pedal all the way down, and it bottoms out, there is another half inch of travel (at least) left in the throttle. When you push down on the pedal, it goes down almost two inches BEFORE the cable starts to get tight and starts pulling the cable. Thanks for the reply... I like your idea about printing his procedure and putting it in your manual.

My 1120D runs great, but does 10 or 11 miles an hour. I'm sure there are other things like you mentioned, and cleaning the spark arrestor that will make a difference. But if the throttle isn't physically being moved, nothing will help.
 
So I thought I would update. Cable is too long, we put two large split shot on the cable under the pedal and got enough slop out of it that we could use the built in adjustments on the cable to get it perfect. Got the idle down and smoothed out and Step son helped me with the HST linkage, now it's correct. Bottom line, I went from 11 MPH with my toe on the top of the pedal and it smashed all the way to the bottom. Now it does 22 mph with you're foot on the middle of the pedal and pressed down. It runs great and responds much more quickly and doesn't lunge into forward or reverse. It sounds like a sewing machine at 12 MPH which is really about as fast as I run riding around the farm.

I think I'm going to be very happy I bought it. Thanks for the help
 
the cable length isn't all that criticle. the length of the throw is though. when you say peddle bottoms out???? is that with the stop bolt adjusted all the way down?
 
Yep, we adjusted it down and then removed it. Still couldn't get enough travel to make it work. Put two large split shot on the cable between the U shaped bracket and the head of the cable. That shorted the cable enough that we could use the nuts on the engine side to adjust the throw until we got it perfect. When the peddle is pushed, the cable starts to move immediately and doesn't stop moving until the throttle almost touches the stop. About twice the RPM we were getting before and the peddle doesn't move over an inch before the cable starts to move. We didn't change the wired shut throttle stop, just changed the cable so we could reach the throttle stop when you step on the peddle.
