IH 2504 What are all these levers?

I recently purchased an IH 2504 with a FEL. She"s not pretty but it starts, runs, moves, and lifts pretty darn good. I have purchased an operators, parts, and service manuals. In the meantime can somebody help me to identify and tell me what all these levers do?

Thanks.

the torque amplifier lever could also be a reverser lever instead (you can have one or the other, not both). Can someone tell the difference from the picture we were given?

if the transmission lever doesn't have reverse that lever has to be the reverser lever. The reverser lever gives you reverse in all transmission gears. It would be more common on an industrial marketed tractor like the 2x04 series.

That is definitely a Torque Amplifier lever. BTW, torque amplifier is a two-speed "powershift" that gives you two speeds for each gear.

The reverser lever is a simple rod with a ball on top IIRC. It goes "over center" for forward or reverse.


Sit in the seat, drive around, and try the levers. 100% guaranteed that none of the levers are for an ejector seat, and there are no guns or missiles or self-destruct. You will be safe.

If you are really antsy about it, make sure you are in an open area when you start playing, and make sure you know how to shut the tractor off with the key to make it stop if things get out of hand.

I see you have a hydraulic remote valve with broken off lever and no pipes plumbed to it. It looks like you have a small red arrow pointing it out in the top picture. hopefully the missing plumbing has plugs in its place on the valve. once you find a lever and get new couplers and plumbing (hydraulic hoses+fittings) you can lift a pulled implement. It looks like your loader is powered with an external pump, maybe off the crankshaft?

We'd like to see more pictures of your tractor and if you have more questions we'll all try to help. There should be plenty of tin available to replace what's missing from salvage yards. a 504 should be 95% the same tractor--if you stick to utility models.

That looks like a torque amplifier as it has the hand lever. Mine has the shuttle shift just a shifter no hand lock.

Thanks for the Info Karl. As far as that broken hyd remote valve, it looks like there is a main feed going into it but nothing coming out. So is this lever for lifting and lowering the 3 point hitch attachments? Sorry for all the questions but my manuals won"t be here until mid next week. Thanks. I'll be away for a couple of days but will post a bunch more pics on Sunday or Monday.

Thanks for the reply Steve. I think from Karl's and your responses the broken lever is supposed to raise and lower the 3 pt attachments. Okay so what are draft control levers for? Thanks.

Yes, the tranny shifter does have reverse, so it must be the TA. I'll have to try it out the next time I fire her up. I guess I can verify what it is by putting the tractor in say 2nd gear, then engage that lever, then release the clutch. If I go forwards it can't be a reverser correct?

The draft levers are your 3 point lift control. the other broken lever is called a remote or an auxiliary control valve (and a few other names from other manufacturers/people).

of the draft levers, you're missing the quadrant which will identify and keep the levers from over-traveling. the inner most lever is called your position control. It is used to raise and lower your 3 point. the forward most couple inches of travel will affect your draft control response speed. The outer lever is your draft control lever--you may never use it, especially if you don't use a plow or tillage implement. for non tillage work, you want it all the way forward so the hitch behaves predictably when lowering and raising. It's best to get a manual--there may be excerpts from an IH tractor or plow manual on archive.org. If you can get a glimpse of the hitch pages from any IH tractor x06/56/66 the use of the levers is the same.

The remote control lever is for lifting a towed implement (i'm over simplifying) or running a hydraulic motor. examples on a farm would be lifting a pulled disk harrow, a dump trailer, and an end gate on a manure spreader. Some people controlled their loaders with that lever--they relied on gravity and a latch mechanism for the bucket control. The hydraulic motor usage with that particular tractor would be very limited, but it could be used intermittently for tasks such as rotating a snowblower spout.

hope this helps

The way to test the TA is to start moving with the lever forward, then pull it back. The tractor should act like it shifted to a lower gear, and move forward more slowly.

In the first pic, the inside lever should be the draft and the outside one the position control (lift). Also in the 1st pic the red arrow pointing to the stub of a lever is a single rear remote valve. The port are on the bottom of the valve, I assume they are plugged. Looks like your quadrant shafts seals are leaking too by the wet axle. Join the crowd, my 504 is bad too. PITA to fix.

2nd pic, IPTO. You can engage and disengage w/o clutching. Nice to have.

3rd pic. Obviously the center lever is the xmission. The LH lever is the TA. Forward is direct drive and back is TA. Shift it fast either way and DO NOT SLIP IT!!! Shift it like you stole it.

Enjoy,

Charles - thanks for the info. I checked and the remote valve ports are plugged on the bottom. My quadrant valve seals are leaking. Yeah, what isn't leaking on this beast right now!

Do I need to use the clutch to shift the TA?

My PTO shaft is continuously turning. I cannot get it to stop. If I try to push the PTO lever to the rear it just won't go. I didn't know if I should try to 'gorilla' force it?

Your PTO may already be engaged... did you push in the button and push it forward? It should actually be spring loaded forward when you push in the button on top of the lever.
You do not need to use the clutch for the TA.
