Case Garden Tractor and Ingersoll Garden Tractor. The Original and best improved Travel Control Linkage. There is a copy cat version that costs more and is not close to as good as the Hemlock Case Guy Version. I have installed more of my linkages than the copy has sold.
I am the original. I am the guy that "invented" an improved linkage.
The first version of my linkage had the larger joint for the control lever end. It has a 5/16" stud. that means that you MUST drill the hole of the control lever to fit the larger stud.I did that just a fewtimesuse a joint that is plenty strong and does not require extra work or any drilling.
I would never build something that someone else created, ever.
Jumpy Tractor?Wife and kids scared to drive it?Not as fast in Forward?
Your travel control linkage and lever pivot bushing is worn and that causes the negative operational experiences. Sound fancy enough? This is a kit of various standard parts but I modified the parts to work best in this application and to make installation easier than if they were left untouched. And then I have assembled them into a kit that will certainly not only restore your tractor use experience to the same as new but this kit is better than original.
This linkage will fit all 446 and 448. 3000, and 4000 series tractors.Then by serial number on these models;220-9656747 and up222-9658189 and up224-9667000 and up444-9661261 and up
It does not fit the early model tractors or any of the loaders in the 600, 6000 or 7000 series.
It replaces items 5-10 in the speed control parts diagram that is in this post. Check to see if your parts match the diagram parts. If they look the same, they are the same. Some of the part numbers changed over the years, but they are the same part.
No more wimpy inline link, item 8, that has always worn out first. The spherical rod end is many times stronger and durable
I have posted videos to help you understand the installation on YouTube; Hemlock Case Guy., Case Ingersoll End Jumpy Tractor.
It can be fixed and act like it did when it was new. This assembly once installed will change your tractor.
Please contact me for any help you may need. And check my Facebook page and YouTube, Hemlock Case Guy. I have posted how to videos and other generally helpful information there.
Traditionally, those that were at least partially aware of the fix would replace the Travel Control Valve inline link. It is C19025 from a parts dealer. When less than 1/16" of slope matters and the control rod gets worn and it makes the hole in the control lever bigger as well. The worn out hole in the control lever problem is a problem. All the replacement parts, shipped, from a dealer would be almost $50 and not fix the control rod slop. Then if you really want to take out the slop you replace the plastic washer that the control lever pivots in C21518/C44383, which replaces a plastic washer with a bronze thrust washer. Reference the parts manual page. This washer is in my kit.
I have a kit that I searched every crevice of the internet for and found parts that are way overkill and some that are exact duplicates. Way overkill is a rock-solid replacement of the control rod with a bolt that goes into the sloppy hole replacement. And it is the most heavy duty control rod end made for the application. And now I went even further and have a way more robust replacement of the inline joint. The heim joint comes with a grease zerk that I remove because it gets in the way during installation. I have started including the removed grease zerk in the bag. It is not needed but you may re-install it using a 7 mm wrench or socket.
It is not an easy place to get into. The 3 digit tractor has the front PTO lever in the way of the travel control lever for changing the washer. I usually do this job when I have the engine and hydraulic tank out of the tractor. It is very easy to do at that point.
You can also check the linkage adjustment for center from the control lever operation. You will be centered if the lever reaches the same point in both directions. Just make sure that you are looking straight at lever to get it dialed in. Another hint is if you lengthen the linkage that will take away reverse and add to forward.
