I agree the needle scaler is the fastest and easiest way to knock paint off cast surfaces. Very minimal mess too. Stay away from sheet metal, lines and brass fittings. You could do one pass with a wire wheel after if needed. Everything else I cleaned inside a blasting cabinet. I personally wouldn't buy a tractor that was sand blasted complete unless it was soda blasted.

I'm convinced that you guys are right. I will take my time and wire wheel this thing... and look into that needle device as well. So.. here is my new plan..... Mechanical work, Wire Brush, Paint... I'll be sure to send progress pics!

My battle plan for mine is to needle scale everything but the sheet metal and use chemical stripper on that. I’ve been using klean strip aircraft stripper on my truck rims with really good results. I first used the spray and then got the can shown below brushing it on. Definitely prefer brushing it on. On the stuff that was loosened by the stripper but didn’t want to scrape off I used a wire brush in my diegrinder which blew it right off. I followed it up with soap, water, and a brush. Worked perfect.

My preference would be to clean first, then repair (I hate working on grimy parts), then prime, then drive it for a month. Something will likely leak, and you don't have to worry about that fresh paint. Once all leaks fixed, then clean again, and paint.

I used that same aircraft stripper when I restored my dad's old aluminum jon boat. I will try that on the cub's sheet metal. Another question... How long after paint removal will it take for surface rust to develop, let's say... if I were to remove paint and then make repairs over several months... It will be stored in a garage during the project.

If you remove paint from sheet metal plan on priming it right away. Any amount of moisture in the air will start the rust process pretty quickly.
Even though I may have something in my garage or barn I can often go out to find the chrome covers on my bike fogged over with moisture. On bare metal it would have rust starting.
At the very least rattle can it with primer and get it under some type of cover.

Funny... the mechanical work and elbow grease required doesn't scare me... but the logistics of a project like this are mind-boggling!

If you mean something like this be aware it is a very aggressive grinding wheel. It will take paint, rust, and steel with equal ease. I've had good luck with a needle scaler and wire wheels on a R/A grinder. Use good quality wire wheels, they last longer and are somewhat safer to use. As mentioned above wear a face shield, leather gloves, and heavy outer wear. Even so you'll picking wire out from surprising places. lol Good luck.

The squeaky wheel may get the grease but it's usually the first to be replaced!

I know what you mean. It can seem bigger than it is. Take the tin off an go at the heavy metal with the needle scaler. You might want hearing protection as it can be loud. Knock out small sections and you’ll be surprised at how well it works in fact I doubt you’ll be able to put it down. Just remember it’s an air tool so you have to oil it periodically.
Before painting I’ll blow over it with the wire brush and wipe it down with lacquer thinner.
My biggest problem with getting my tractor repainted is taking it out of service for enough time to get it done.

Well, I'm asking Mrs. Santa (AKA, my lovely wife) for a compressor this Christmas. I think the needle scaler would make a great stocking stuffer! LOL, I borrowed equipment when I restored my boat not thinking that I might ever tackle the tractor... but alas, here I go. Thanks again!. All of your collective advice gives me a much clearer picture of how to tackle the project with the most efficiency possible.

IMHO, the most effective tool for rust removal. Wear a thick shirt, gloves, and a face shield, because you will get wires thrown at you, but the results are worth the hassle.

Try to match the cfm output of the compressor to what the tool requires (or more), or you'll find yourself waiting a lot for the pressure to build back up,

I'm glad you mentioned about the compressor output. I only just discovered that paint guns need to be matched to the compressor. After lots of searching, I discovered one Harbor Freight unit that puts out 6.2 cfm @ 40 ps (match for those popular Harbor freight HVLP paint guns. I had yet to consider output for the needle scaler tool I plan to use.

To be clear, Matt's pic above is an electric angle grinder, not an air tool. I was also referring to an electric. Bob's point is a good one if choosing an air tool.
