HST Just Won't Stop, Quit, Woah!

Yes, all of the DA units have the new spring. The new spring can also be installed on older units, but they recommend replacing the pivot w/ the "B" on it due to the added tension of the spring.

Re: HST Just Won\'t Stop, Quit, Woah!

Today I had my trailer hooked up to the back of my TC-40D. It was filled with a load of cardboard. I was at about 2000 RPM and pulling it up to my burn area. This time of the year the area where I burn is extremely muddy. Anyway as I approached the wire cage where I drop my load I took my foot off the HST pedal and the tractor did not stop until I hit the reverse pedal to center the two. ouch!

Later in the same day and again with the trailer on, I was taking a load of new inventory to the packaging area. This time I was traveling uphill and when I took my foot off the HST pedal again it refused to come back to the center position on its own. ouch again!

As I said in an earlier post, the HST pedal does feel smoother since the kit was installed. However I'm now a firm believer that this kit is not going to be the permanent fix that we have all been hoping for. /forums/images/graemlins/frown.gif

Mike,

When I was having the same problem with my TC45D I mentioned to my dealer the "repair / fix" of spring adjustment and lube mentioned in many of these posts. He said, and I quote, "That may fix the symptom but not the problem". So it took a bunch of service calls and three (as I recall) transmission replacements before it seems to work right. Hang in there and good luck.

Re: HST Just Won\'t Stop, Quit, Woah!

Day before yesterday, the work was done on my TC35D. The dealer fixed my hydraulic oil leak (it was the test ports) and ordered the parts I requested to fix the HST pedal return problem. He called me to advise that the pivot arm and spring did not need replacing: just the spring. He said on earlier tractors, the pivot arm broke at the weld, but my tractor was newer and didn't need this fix. (Jinman's problem with his break???) They replaced the spring with one that looks just like PineRidge's.

My tractor now performs much better. When going uphill under load, the tractor stops within a few feet, rather than acting like the cruise control is activated. I'm happy with the fix.

AFTER havin the fix, I read the thread by PineRidge. I guess I'll have to watch this problem ..... His cure for perhaps more hilly property may not have proved as satasfactory. Thanks for alerting me to the spring change anyway! /forums/images/graemlins/smirk.gif /forums/images/graemlins/wink.gif

My tractor is significantly better, but not perfect. I can live with this now. Perfect would be like it stops on level ground: On a dime with two cents change.

Another topic: I took my loader off for the first time today, then put it back on again. What a joy!

My loader on my 8N Ford was a pain to get on and off and years ago cost me a trip to the emergency room to get my finger sewn back on! /forums/images/graemlins/crazy.gif This is a wonderful system! /forums/images/graemlins/blush.gifo /forums/images/graemlins/grin.gifo:

Kinda makes you want to do it two or three times just for fun. /forums/images/graemlins/smile.gif /forums/images/graemlins/grin.gif

Jinman, you hit the nail on the head!!!!

The comparison makes it worthwhile! /forums/images/graemlins/laugh.gif

Re: HST Just Won\'t Stop, Quit, Woah!

I wondered about the newer units having the new pivot if they needed to be replaced or not, and was going to compare the new pivot to the one on the tractor before I started tearing it appart. I wasn't sure if it was just the weld issue or if they changed something else, my dealer rep. was not clear.

Re: HST Just Won\'t Stop, Quit, Woah!

My dealer seemed to think it was just the spring that needed changing. He mentioned the welding issue as a past known problem that had been corrected during production.

Re: HST Just Won\'t Stop, Quit, Woah!

I've been thinking about this problem quite a bit the last couple of days and have an idea. Looking at the pictures posted here it looks like there is room to do it. Maybe an engineer can jump in and give an opinion, but if the arm that the spring hooks on on the pivot was longer to put more leverage on the roller on the "B" plate, if that would help the return problem? I know it would probably make the pedal harder to push, but I think it might be worth it. Or if the angles on the "B" plate were a little more gradual? I'm not volunteering to test these theories or advising anyone to modify their units, just thinking aloud.

Re: HST Just Won\'t Stop, Quit, Woah!

I went out in our yard to look under one of the new DA units only to find the two we have are both standard ARG!!! I wanted to see the new spring to compare it to an old one. Guess I'll just have the parts man order one in.
