I have a buddy selling his rototiller off of his sub compact Kubota. I am really interested in buying it, but I was told that small rototillers with a 540 won't hold up to a bigger horsepower tractor using the same 540 PTO???? Is there any truth to this or is the guy just blowing smoke up me? I didn't know if they had different gears or something
 
If it has a shear bolt, or slip clutch, they will last. The real issue is how slow the tractor you will use can go in 1st gear. few tractors made for conventional tillage will move slow enough even in 1st. What tractor are you contemplating using? Jim
 
It will work but if on to much tractor I could see you being able to tear one up. Thats why I always liked my smaller tractor on post hole digger, it would stop tractor before busting anything up.
 
Look on Tractor Data .com to see how slow your tractor will go at PTO rpm and low gear. 1 mph is about as fast as they can be pulled doing a good job. If plowed first, or sandy loam, maybe 1.5 mph. Jim
 
Agree with all so far. If you have hard soil I would tell you to make three or four passes getting a little deeper each pass. Roto tillers there is one heck of a lot of action going on under there. Tooo much power will give you false confidence and that leads to busted equipment. Your ground speed must be what a snail would do. My dad has a big Howard Rotovator and it was everything a 460 could do to handle it in first TA. Slow and easy is a must. You get a fantastic fluffy seed bed when done.
 
To make it easier on the tiller I always tear up the ground first with something like a chisel plow or 3pt ripper.Have an old JD 3pt implement that looks like a cross between a chisel
plow and a cultivator works great. Then finish the seed bed with the tiller puts a lot less wear and tear on the tiller which is the way more expensive machine to keep up.Plus it
ends up being a better seed bed overall than just using the tiller.
 
I think there are 2 key things PTO speed and going slow. So check out both on friend's Kubota to see if they are compatible with your tractor.

Aren't sub compact cat 0?
 
A subcompact Kubota I think would be a cat 0 hitch, a compact would be cat 1 hitch while your Case would be a cat 2 hitch. No way to mount that tiller on the Case. If it was a cat 1 hitch probably be able to hook it up, a cat 0 hitch or subcompact hitch no way to mount.
 
Have a kubota BX2200 with a King Kutter rototiller

I use a standard category 1 quick hitch for the 3 point. Had to add a few washers to the lower 3 point pins as the lower limited cat 1 pins are a few inches closer together

The King Kutter has a slip clutch so the higher HP isn't a problem it will just slip before damage is done if correctly adjusted

The big problem is the length of the PTO shaft. It's really short and won't work on a normal cat 1 tractor.
 
If your going to purchase you'll need to purchase and install the following

1.) new lower 3 point hitch pins to replace the cat 1 /cat 0 pins that come with the King Kutter

2.) half a dozen or so washers to push out the lower pins - 3 or4 on each side should do the trick or just mess with the tractors 3 point stabilizers or unhook

3.) new/used 540 PTO drive shaft with the proper length and slip clutch. You can remove the current one as it has standard 540 splines on the rototiller gearbox.

As an alternative to #3 you could replace the PTO tubes on the current drive shaft with longer ones

If you do the above it will work. But only till 4 feet in the center of the tractor. Translation - you will always have tire marks in the tilled area

Good luck
