I currently have a little diesel Kubota with a 4 foot tiller for doing my food plots. My tractor isn't quite big enough tho because it always overheats every year. I just recently found a John Deere 830 for sale. This tractor is plenty big enough. Probably too big. The only question I have is about the rear pto. The guy that's selling it tells me that the pto rpms is whatever the tractor is running at. I.e. Upwards to 2000 rpms, which would kill my tiller. Secondly, the pto only engages when the tractor is off. Does it need a new clutch? Or is it something else. Once u engage it, then start the tractor it's good, shut off the pto and try to reengage it, it won't work, just grind. Thoughts?
