I just picked up a well used bx2350. So the wallet is pretty empty. I was wondering if anyone has taken a bolens shaft drive tiller and converted it to 3 point
Most important is to check the rotation direction of the Bolens tiller. If the rotation is the same as the Kubota and the tiller you have is designed for the same rotation, I can't see any reason that you can't make his o work.
Figure out the rpm the tiller is designed for first. I almost bought an old John Deere tiller then learned it was designed for a 2000 rpm rear PTO speed. You should have 540 rpm at your PTO.
