What is consider normal rust on these cabs
4430 4440 etc

And what is the best way to repair lower parts of the cabs like under the seat and side panels on the cabs

You will get rusted pans and side panels because the rubber mats are not take out and the floor cleaned under them. When I run into this problem I do several different things.

If the tractor is just going to be a beater/work tractor, I just clean it up with a wire brush on a 4 inch grinder. If the holes are not too bad just fiberglass and mesh. If they are worst I cover with sheet steel and spot weld it in. In these kind of "fixes: I seal between the two pieces of metal with silicone caulk.

If the tractor is going to be rebuilt/painted, I remove all the rear/side windows. I then take both doors off. I remove the seat. I scrap all the old foam interior out I can get. then I tape/paper over the inside and out of the remaining windows. The then sand blast the inside and out of the lower cab. Usually up to the bottom of the fenders. I then cut out all the bad metal. I weld in new sections. Grind/fit so they look like new. Then prime and paint. New interior/seat and the cab is good other than repairing the AC.

Is this a pretty easy fix I’m assuming meaning would want to know different methods of sealing and fixing it

Well if you can weld thinner sheet steel it is not hard to do. As for sealing it, that depends on your end use. What I have started doing to my "working" tractors is to clean the lower floor and pan area then roll on pickup bed liner material. This area usually rust form the inside out because of dirt/manure/water/snow. So if you seal this away from the metal it will last a long time. The areas under the seat usually get nasty from the interior being shot and then windows/doors left open to soak everything down. Then the accumulated dirt and old foam just hold the moisture and dirt there to rust the steel away.

Best way to prevent your cab from rusting is to keep it cleaned out. This does not mean waxed and spit shined. LOL Take the mat out every now and then and sweep/blow the dirt out of the cab. Keep the doors and windows shut. Keep an eye out for water leaks if the tractor sets out side much. One the out side try to stay out of road salt if you can. If you run on the road then flush/wash to outside off when you can. Letting the dirt/salt lay under the cab will rot it out faster.
