Good day, happy to be here, been awhile. I have a 47 B fresh bore 90 over, 29 HP. on dyno. I need a disk, wanted to ask if a 8ft. should work? Need to know, differences in the John Deere KBA 8ft. VS the John Deere RWA 8ft. OR what do most folks recommend, as I am out of work, a fair value disk is what I am trying to look for. Thanks for any and all input; Bob63

RWA a good disk. Normally I would caution against pulling a
disk too deep or too fast. Will not be an issue with the B.

Bob
Welcome to YT
I never liked a JD RWA disk harrow. Due to the fact that the disk gang angles can't be adjusted the RWA has a history for ridging the soil. A KBA is a nice light duty disk harrow. My JD BO pulls my 6' KBA very well so I think your '47 B should handle a 8' light duty disk harrow just fine.

Location of implement has a large bearing on implement value but I gave $300 for my pull type KBA.

Thanks, I will focus on KBA, I am in south central Pa. Having a rollback service ready, is another part of the puzzle.

Another older JD disk model you could consider is AW if you can locate one that is small enough for your tractor.

I run only John Deere Eqimpment on my farm. That being said I think
that the KBA disc is the worst disc John Deere ever made. I have
used one for 3 years 400 acres or so. The main problem is it really
hills up the dirt. Also the frame is poorly designed, so it has a
tendency to brake. I worked on an RWA once, that looks like a really
good disc. I?m looking for one now.

I either have a 10' or 12' RWA disc. I'll have to go back and remeasure it, not sure at the moment. I like its construction, however mine does ridge also. In the full down position it is a load for my 1950 G. I would rather have an 8' model. I have never used a KBA, but it's construction looks a little hokey to me. The gangs are held on by chains at the end of the lift tube. Maybe this gives it a little more floating capability and adjustability, but I don't know. A little story about my RWA. When I bought it the previous owner loaded it on my trailer sideways with his excavator. I had two foot or more of tongue hanging off one side and another foot or more of disc hanging off the back. Pretty nervous haul going home. It wasn't until I got home that I noticed the pin to remove the tongue for trailer transport. When I looked at the disc I never saw that pin and the previous owner never said anything about it either. I don't know why I couldn't see it earlier, but it would have made for a much safer hall home. Oh, one more thing. I clipped the corner of the guys barn with the disc when I went to leave. I did stop and point it out to him, but I still feel bad about it to this day.
