Hello, i have done some searching and already suspect my cam follower pin is bad, but wkndering if something else is at issue too and would like to have all fhe parts in hand before i rip it apart.

Problem started when using my back blade to plow snow...all of a sudden the lift stopped lowering. Playing with the lever did nothing and through some fluke i got it to lower once more. one more pass and i went to lift the blade. It lifted slow and only came up halfway. Would not go back down at all. Stayed up over night for several days. Pulled the side cover and the lift control arm appears to go up and dow. But not back and forth.

If i manually push the lever back it lowers. Then if you move the lever to the full up position, it raises halfway unledd i lightly pry the internal lever forward. Do that and it raises fully and will also lower on its own with the touch control. If, on the way down you move the lever to raise, or stop it lowering, it will stop then not lower the rest of the way until i manually push the internal lever backward.

Is this all follower pin? Or do I have two issues at play?

Oil looked ok when i drained it and I changed it last summer. Tractor stays in the barn when not in use.

It's possible that the position control linkage spring is broken. I have seen that two or three times over the past 50 years I've been working on these old tractors and it can be hard to figure out. Only way really is to take the cover off and give it a good look.

Sounds like you got problems with the control valve sticking. Most liking sticking is, crud in oil or frozen ice in oil. Many time in chamging oil, it hard to flush out all residue stirred up and it latter becomes lodged in valve causing erratic action. When you move the control rod, forward and backward, you are helping the spring overcome the sticking. In winter any moisture condensation or water, freezes and forms a stickie mess, like "sluch" to recondition oil, you need to thaw out the slush, so the moisture and oil separate (Oil floats on water). Loosen the drains in a warm shed and let the water drip until oil appears. If its crud, you may have to filter the oil, or replace oil again. A new control valve may also be needed.
I would do any or all the above before I tore the top cover off, for replacement of cam pin.
