End Jumpy Tractor Linkage Kit
Posted: Sat Apr 17, 2021 3:24 pm
I was a guy that would always replace the inline joint of the stock travel control linkage. This was to end the forward lurch of the Case/Ingersoll tractors. Replacing the inline link helped but there was still a lurch to forward engagement. I then added changing the washer that is held in the steering support from the stock plastic washer to a self-lubricating thrust washer. This to helped. But, there was still play. The remaining play was the very simple control through the tab in the control lever. That had to go. I also never liked that the inline linkage end just had that rather small ball and socket that actually has some play very soon after use. Yes, I would lay under the tractor, a lot, looking at the whole thing.
I set out to make a better mousetrap or linkage. It was not easy. The spool end is 5/16" and the travel control lever end is 1/4". And then these linkage parts are not cheap. When buying one at a time you end up with a bit of money into a linkage and I wanted to share and make a little while giving up my time to assemble the parts. I spent many hours searching the internet for suppliers and different joints that could be used, many hours. I eventually found a way to go from 5/16" to 1/4" and increase the durability many times the original linkage.
I created a video about why the linkage slop creates the jumpy start or lurch. Then I created a video for at least one way to install my new linkage. They are on my YouTube channel Hemlock Case Guy.
I sell the linkage on eBay as hemlockcaseguy. I have sold 100's of the linkages. In fact, I buy my parts in lots of 100 to get the discounts so I can sell a linkage no more expensive as new stock parts but mine is much better than stock. The parts I use are modified to work. Having installed these myself so many times the tweaks were gradual in some cases to ease the install. I have it dialed in at this point.

In the listing, I have the tractors and serial numbers that the linkage can be used in. It does not fit the older tractors or the loaders. The 4 digit tractors are by far the easiest to change the washer on. The 3 digit tractor has the front PTO rod that is in the way of the travel control rod being able to pivot forward far enough to change the washer.
