JD 790 and refurbished \"John Deere\" rotary cutter
I took on a project last year, but I haven't taken the time to post the pics. My dad had an old BMB brand pull behind rotary cutter that has been lying "dead" out in the field for about 10 years now. Last summer I decided to bring it back to life, while at the same time, converting it to John Deere (more of you should do that as well). I had the unit completely sandblased. I primed it and painted it JD Green with JD Yellow trim. I straightened some of the sheet metal. It still has a few imperfections, but for the most part looks good. Also, one of the wheels was off of it due to the fact that the wheel bearing fell apart. I cleaned this all up and got new bearings and seals for it. I also got some used tires for it that were not all dry-rotted. I greased the PTO shaft and changed the gear oil too. The blades were surprisingly sharp so I didn't even have to sharpen them. It now runs like a champ! The only issue is that the front oil seal leaks a bit. I'm going to replace it soon. My theory on that is that the gearbox doesn't have any kind of vent like the newer ones do. When I replace the seal I'm going to add a vent so that when it gets hot, the extra air pressure has somewhere to go. By the way, I know this rotary cutter has had a hard life. I remember when I was a kid my dad ran over all kinds of stuff with it. I remember seeing it jump off the ground and shear I don't know how many shear pins. He did all of that with an old Farmall "M." I personally think it looks better behind a green tractor and it cuts very well. It almost looks like a finish mower cut....
The best part is that I've only got about $150 in the whole project!! Does anyone on this board know any thing about BMB brand cutters? See attached pics.
