TO 20 Hydraulic Lift

Hello,

We recently bought a 1949 TO 20, and cannot get the lift to work at all. It remains in the uppermost position regardless of any control lever movement.

I don't know much about farm tractors.

Can anyone help me troubleshoot /diagnose the problem please?

Thank you!
Rick
 
I would suggest that you get a copy of the shop manual from this site for your machine.
If they don't have one try Jensales.
 
It should creep down with the engine off.

If it stays up, solid, there is a mechanical problem with the cylinder or linkage under the top cover.

If it creeps down, but goes up as soon as the engine starts, there is a problem with the control linkage or valve down on the pump.

Yes, a shop manual can explain it better than we can.
 
In the photos the T shaped object 15 on the pump is the valve it is attached the the bottom of the fork 17 on the other image. You will need to open the cover with the lever to feel if they are connected. You can either drain the 5-6 gallons of oil from the transmission/hydraulic area or put your hand into the oil and feel for it. I would suggest draining it all for a good inspection. If you end up having to open it up fully, please get a manual to help

Hello,

Thank you for all of your help!

The lift hasn't crept down since my last post about 6 days ago, except maybe 3".

If I grab the arms I can move it up and down about 3", but it won't go any farther down.

Do you think I should take the cover off and have a look?

Thanks again,
Rick

Do yo have any weight on them?? It really helps if you have several hundred pounds hanging there like a 2 furrow plow.
 
No sir, no weight on them.

I'm about 240, if I try to stand on them do you think that would be enough?

Well, I was thinking that you are not likely to want to sleep on the hitch 24/7 for a week. :p :lol:

If you want to try to get them moving continuous weight could be a big help.

It is actually a performance measure. If you can turn the tractor off with the plow up, and it holds for 10 minutes, everything is OK. Just do not leave it up after the test. Always lower it to the ground.
 
Yessir, you are correct!

I'm not sure how to attach anything to the hitch to test it, as it won't lower enough.

I can't get the hitch to move at all when the tractor is running.
 

What ever implement you have, can you put it on some sort of platform 12-16" or whatever you need to match the height of the lift arms and then back up to it to hook it up? Just a thought.
 
And a good thought too...

All I have is a mower that's pretty heavy.

If I can get it hooked up, and it DOESN'T bring the lift down, what could that mean?
 

Maybe this will get you started. The lift arms may be rusted in the lid. http://www.greyfergieforum.com/viewtopic.php?f=21&t=2452

This will take you to a competitor's forum. :p
 

As Tom H. said the T valve may be disconnected or stuck In. If you poke about inside from the left and right inspection plates. If stuck in the oil will not bleed out and keep up the arms. This will show you how the system works. http://www.fofh.co.uk/tech/lift.htm
 
If you have a drawbar installed, you could try to pull the lift arms
down with a cable type puller. We call them a come-a-long around here.
Not the same tool as a cement use come-a-long though.

Sounds like the control valve is stuck. Remove the RH the side plate and WITH THE ENGINE SHUT OFF, reach down in the oil at the end of the "H" shaped control fork and fine the "T" shaped control valve stem. The ends of the "T" should be in the sockets at the end of the control fork. Push forward and then pull back. The should be about 1 inch of fore and aft movement in the control valve. Move it back and forth to see if you can make it "unstick". Check the linkage to make sure it is hooked up properly and all the springs are in the correct place. then star it up and see if it responds to the lft lever movement.
