Believe it or not, the cab was in great shape. My great uncle (in the picture) bought the tractor new. All we did was repair the sheetmetal under the black stripe on the roof, install a new interior kit, and added new decals. The glass is original. Wiring was fine. Seat is original. My great uncle kept a seat cover over it, so it does not have any stains or holes. All interior features still worked including the ventilation system. I did replace the radio. We also gassed up the air conditioner system and sealed up the ductwork above the ceiling.
The tractor interior is the western style. I had a hard time finding the kit, but luckily I was searching a forum group and found a vendor. To begin with, I bought a brown replacement from IH, but just wasn't totally satisfied. It was a blessing when I found the original western style pattern that IH could not get.
Mechanically the tractor is great. We replaced the clutches in the pto. I just bought 2 new front tires and plan on replacing the rears next year.
The 520 is my baby though. I am 32 years old and grew up driving the tractor since I was 3. I have spent many hours in the seat disking the ground and raking hay. I would hate to see how many hours it actually has on it. My dad and I went through the entire tractor front to back on the restoration. The only item still lacking is the sheetmetal plate on the back of the seat. I can't find a decent one anywhere. Other than that, the tractor is all original including the 3 pt hitch and center link.
I show the 520 and the Model A. Although, we still use both of them raking hay to stretch their legs from time to time.
I bought the A about 8 years ago. We went through it mechanically front to back about 5 years ago. It already had the older paint. It just received 2 new rear tires. I am planning on it looking drastically better than the 520 when I finish painting it this spring. I am currently disassembling it, sanding, and filling all pitted areas of the castings. I plan on the frame work looking as slick as the sheetmetal.
I bought the JD 4000 about 3 years ago from my wife's father. My wife's aunt and uncle purchased it new. I have fixed all the leaks, starter, new batteries, and new tires all around. I have been buying cosmetic parts and just about have everything I need to start the paint process. This tractor will receive a paint job about like the 1086. I still use it daily, so it will get scratched and scuffed.
I wish I had a digital picture of the BF Moline. Great little tractor that we still use. I am currently buying parts to restore it.
