Not much help, but that's a nice 2072, you have there!

If you are referring to the lift stop knob I do not have on on my tractor. Not there when I bought tractor.

do the pictures show what you are looking for?

Not really. Take one from both sides far enough out that we can see the entire undercarriage and deck mounting points. Another like pics 2 and 3 just further away.

Is the fourth pic down with it in the fully raised position?

Also, you say that you rebuilt the power steering. Sure you got it back together correct? No way it has air in it, but it may be low on pressure. How's it steer? Does the relief valve whine when you hold it in the up position?

I will get some further away pics. The fourth picture is in fully raised position. I had a hyd. shop rebuild the power steering. It steers great from stop to stop with one finger no binding or weird noises the exact way it did before the rebuild but without leaking. I gave the shop the manual for the rebuild and the rebuild kit. There does seem to be a slight whine when the lever is held up after fully raised. I will have to get pictures tomorrow. Kids school concert tonight.

Take a look at the bracket on the opposite end of the lift cylinder. Make sure it isn't bent.

Also, I believe, there is supposed to be a pin here. Not locked into the lift arms, mind you, but there. Something about this pic doesn't look right to me.

I can explain what I see more, but if I were you, I'd take the deck off. Lower the lift all the way. With the tunnel cover off, reach under and push the lift arms up all the way. Make sure they will go all the way up, and look at the contact point of the arm where it meets the cylinder. I think your problem is there. If you see nothing, while it's in that position, put a pin in the hole I pointed to. I really think it's supposed to be there. You just pull it out, let your arms fall forward, and reinstall it to "lock" it and give it down pressure.

Removed deck this morning. Removed pin in end of cyl and retracted cyl. Lift arm moves free from end to end. Moved rod of cyl out all the way 2 1/4" and all back in. Reinstalled pin and tried again. Cylinder goes full range hooked to lift arms or not. Checked out putting pin in other hole. The pin would only go through one piece of the bracket hole never drilled through other side of u shaped bracket. If I install a pin here it would only be 3/8" long going through one piece of metal. With the cyl un-hooked I can move the lift arm down until they touch cross shaft which would give me about 1/16" move travel. There are no ware marks on the cross shaft from this ever happening. The front of the cyl bracket looks straight the way it should be. How muck clearance should there be where I have the screwdriver placed with cyl. hooked up. Thanks for any and all help.

Your not quite on the same page as I was.....

Here's the deal. I think it's missing a pin. Here's the pic from the parts book. Pin is circled in red.

Then you need set the lift all the way down, and rot the shaft by hand. Like this.

Then install the pin here.

I'm almost certain that you had a pin here before.

You nailed it, he is missing the pin. This is from an 1882 but same lift setup. Pin goes in through the hole on the out side of the frame. Other pic is from my 1782 operators manual.
