Hydro shift linkage

[Ronald Hribar 127]

I'm working on a foot control for the hydro on my 7117. I'm having a problem with getting the full range forward. Although I seldom use that position. At the end of the linkage at the transmission, there is a spring loaded assembly. This does not allow linkage to move completely forward. I can push on it and the linkage will then move. I have seen posts that suggest to replace this section with a piece of copper pipe. What is the purpose of this device ? Does the linkage move easier when tractor is running ?

"posts that suggest to replace this section with a piece of copper pipe" Purpose of the spring link is to soften/prevent sudden speed changes. The piece of copper tube blocks the spring action to make the control more responsive and prevent runaway when turning downhill. Others may have a different opinion.

That is pretty much of what I remember of the post. I am considering makeing a solid connection at that point. Thank you

Funny that you said that Ronald, I was going to try to do the same when I put the hydro trans in the B112. I want to try to use the variable lever instead of cutting and welding a hydro lever in.

Hope your taking some pictures Ron. Thought about vconvertting the 4040 to foot control.

So far it has been pretty straight forward. Pulled shift lever off tractor. made a foot pedal and mounted it to a shaft that fits into existing linkage. First try was tooooo touchy, making longer pedal so it is not so sensitive. Everything can go back if it doesn't work. Also eliminated clutch /brake pedal. Just using parking brake linkage. Want to put some kind of locking cable in place of that too. All this is to free up space and hands to operate loader that I'm putting on 7116 0r 7117.

Ronald, I'm interested in what you come up with for the parking brake. Would like to be able to more easily set the parking brake. The stock cam lock lever is a PITA.

[Ronald Hribar 127]

What I am really looking for is the old time emergency brake handle that you pulled and it locked in place when it was secure, and then you turned it a quarter turn and it released. Or possibly adapting the new version that they have in cars now between the seats. Only it would be opposite the Mid pto lever. Or just mount a PTO lever on other side and run a cable from it to brake

??I don't understand almost everyone wanting foot control. Every tractor I have driven with a foot control has been a PITAC. I like my lever action controlsm01. Comments made above are a personal opinion and no way reflect on this forum site or any affiliate,:O:D:D.

I personally like the spring box. The sunstrand hydros are way to jerky without it. Nothing sweeter and smoother than the Vickers hydros.

[Ronald Hribar 127]

Nothing that I'm doing is permanent. That is all the changes can be removed and original pieces insalled. With the exception of a few new holes . The neutral switch had to be moved to accomadate foot control. So if I do not like it , I can go back !1

I'm thinking your gonna like it a lot Ron, esp for loader work. Not sure about most folks, but I was only born with two hands:O and find it hard to control steering, hydro and lift in a smooth motion, all while two feet doing nothing to help out.C Not sure where and how you located your foot control but you find it much more comfey if your right foot and left foot are sitting the same. Have run a few that are not built that way and it doesn't take very long to wear on you. My brothers 2 pedal 955 JD really sucks.

[Ronald Hribar 127]

The foot pedal is located at the same hole that the shift lever was in. First pedal was too short and too high. My second attempt has the pedal sitting almost on running board and more of the pedal located ahead of the hole. There is not much movement on pin that goes to linkage. like from 11 to 1 on a clock face. and 12 is neutral. I'll have pictures when bugs are worked out.

I made one by running a rod from the control lever to the clutch pedal. I never use the clutch, so I disabled it and use that pedal as speed control. I posted pictures last year but not sure where to find them. I use A bracket to catch my foot top for reverse. This set up I can use foot or lever. Funny, for years it seemed everyone ripped Vickers apart, so when I finally get A Sundstrand, everyone says the vickers are smoother. Now I have both and can't really tell the difference.

I keep hearing that some people need three hands in tight spots to operate a hydro. I hate to say it, but my clutch pedal still works. When I am in a tight spot, I use the clutch just like I would on a 3-speed. You wouldn't want to "pop" the clutch because it could damage the pump, but gentle usage will not harm the hydro. I use the hydro lever to set the gear ratio of the tranny, just like shifting gears. Once I get out of the tight situation, I go back to operating completely from the lever. I have driven several tractors with foot control of the hydraulics. They are a PITA when mowing a large lawn, because that foot is planted on one spot the whole time. The only reason that I can see the need for a foot control is for a loader or a tractor that is constantly used with a front blade.
