I've read about "Exhaust Lifts" several times in this forum. I've never seen one or understand how it works. Any explanations or photos out there to share??

I would rank Gene Bender of this forum as one of the most knowledgable people around regarding these systems. He should be along at some point and will probably weigh in. Red Power magazine issue Sept-Oct 2003 has a good article with pictures. You can order the issue from their website.

Look at the Farmall A snowplow thread. That tractor is set up with the lift parts for a 2-way plow with exhaust lift.

A simple overview:
Almost all IC engines have an exhaust stream that can act as a compressor.
This can be utilized for lifting and moving implements just like an air cylinder.
In the day, it was cheaper and usable to make a system that diverted exhaust gasses to a cylinder (large diameter) with (I believe) leather seals and attachments to operate different cultivation tools. Hydraulic systems were more precise, and eventually cheaper due to production numbers. Control of depth and down pressure were "springy" and (opinion) that is the major performance issue. The pressure was modest, and it had to be to avoid likking the engine. JimN

The usual setup on a pneumatic lift system, the lift was run to either a fully up or fully down position. Operating depth was set with manual levers. The same concept was used on hydraulic operated equipment on the H and M.
When in good condition, the pressure valve put a pretty tight seal on the exhaust. If you left it closed after the cylinder hit the end of the stroke, it could stall the engine.
I have an exhaust lift on my Farmall AV that I am currently restoring and was wondering if it would be in my best interest to leave it on or just take it off because I don't know if it works or not.
I don't really need it because I don't plan on using this as a work tractor but on the other hand I figure that leaving it on there would probably be the best bet to keep everything as close to original as possible even if it doesn't work properly. I have it off right now in order to get to everything easier since it gets in the way of some components and such.
Here are some pics of the exhaust lift, these were taken right after I pulled her from the barn where she's been sittin for at least 20 years.

Do you have the rest of the cultivator setup? Either way I would leave it on there. Don't see many at the shows. I have the exhaust lift setup on my BN and run a two way plow with it. It works good. The systems are really quite simple to repair and last I looked, seals for the valve and the cylinder were still available from Case IH. Nice find on the AV, looks to be in pretty good shape.

I would leave that tractor as is. It looks neat like that, it ahs the untouched look. Nice tractor though.

Does your plow have the guage wheels and rolling cutters?

I would restore the whole cult. There isnt any AVs around with that set-up and would be nice for people to see how it operates. They are neat sysstems.
As for the cultivators I think they are around here somewhere as I know my Grandpa used them to farm I just hope I can find them!
My thoughts were to restore the entire tractor, paint, etc., and just have it for a show tractor. Or do you think I should leave it the pretty rust color that it is? I power washed it and it's still coated with baked on oil and dirt so I figured some new paint might be good for it.
Sometime soon I think I'll start a thread on it with some more pictures and seek advice on some things.
As for the exhaust lift I do have an original manual on it and thought it might be a good idea to keep it all on there and hopefully get it to a good working order. Might have to ask Gene for some help when I get to that point!
