I have TE-A20 that has a loose quadrant. I can hold it and still operate the lever for the 3 pt hitch. The quadrant is firm when the lever is in the down position but can be easily moved when the lever is raised. The shop manual shows a cotter pin and "key" and I wonder if i lost one of those and that is the problem. Any suggestions appreciated.

Spring may have broken or come loose . Fairly easy to determine whether or not and reattach through the dip stick side cover.
This link shows the spring and how it works .

Hi Charles,
That's a great link, and may help me with my problem. I have a TO-30 and in order for me to lower the lift arms, I have to push the touch control lever almost all the way down the quadrant (maybe an inch from the bottom). If I move one inch (or maybe less!) back up the quadrant from this point, the lift arms raise up all the way. So, basically, the top 80% of the quadrant is totally unnecessary.
I have never operated any other TO-30, but it seems to me this can't be operating as intended. I am wondering if the spring isn't stretched, which requires the touch control lever to be pushed almost all the way forward to lower the arms. I fully realize the TO-30 has no position (height) control, but only has draft control. So, when operated with a brush hog or blade, where in the quadrant range should a correctly operating lift begin to lower? 60% from the top of the range? Anything beyond that point is all the way down, and anything before that point is all the way up? I need to get a Zane Thang or equivalent after-market positioner working before we get snow so I can run the blade at the correct height. Thanks.

If the draft control spring and the quadrant has not been adjusted you will loose the range that the control lever works in. When you move the control lever about 2 3/4" from the top the implement should start to lower. If you need to have position control you can go over to FENA....and they have the plans to build the position control device for free. Basically the same thing as the Zane thing. FENA is Ferguson Enthusiasts of North America.
In the manual I see how to adjust the quadrant, and I tried that to no avail. The draft control spring on my tractor is seized up and I cannot turn it by hand. I've tried different things, but I can't get it turn. So, based on what you're saying, my touch control lever is out of spec most likely due to this draft control spring issue?

Until I finally got the yoke freed up from the plunger on my TO30, attempting to adjust the quadrant made no difference.
If the yoke has rusted fast to the plunger it can be difficult to loosen. In my case I soaked everything best I could with penetrating oil. Eventually I could turn the yoke a few degrees by putting a little more force on it than I probably should have (the plunger shouldn't be subjected to much twisting, so I have been told). Once I got some movement, lots of oil and patient turning back and force eventually allowed me to remove it without ever putting much force on anything. Then I cleaned and oiled everything and it turns freely. When that was adjusted right, the quadrant adjustment was easy.

That will do it as well , the yoke is a pest to loosen , too much force and you will snap the internal connection and need to remove the top cover . There are a few things you can try , the best being heat . Get the yoke red , then let it cool completely before trying to loosen it . You might have to try this a few times but this is usually the most effective way . I have thrown cold water on to them as well when they are really stubborn though that doesn't seem to speed things up . Best release fluid is ATF and Acetone in equal parts , use liberally and give it a day or so to work .
