King Kutter's XB Middle Buster/Sub-Soiler combines strength and durability to offer a tool with many uses. Its tubular steel shank and heavy duty frame construction make a solid platform for the furrower to do its job. The middle buster point is great for laying off rows, digging potatoes pointing a ditch, general field prep, and many other farm, field, and garden uses. The sub-soiler point is for ripping sod and loosening compacted soil for better plant growth and production.


  • Tubular steel shank
  • Heavy duty steel frame
  • Heat treated furrow and sub-soiler point

Great product Review by Atwell Tedder

It's everything I could ask for to use behind my 2370 Kubota tractor. The color even matches my tractor.

Nice value for a 2 N 1 tool Review by Coy

This tool was about the price of what I could find for a middle buster. I wanted the middle buster in order to dig a trench to install a drain line. I initially priced renting a walk behind trencher. That was more than the most expensive middle buster I priced. I have not yet done my project but i have dug a couple of trenches and believe that after added several hundred pounds to the middle buster that it will preform the task quite well. The price for the 2 in 1 tool is great at Rural King

Great implement Review by Bob

I bought it for trenching, both for underground wiring and drainage.
It works great for both.

Plow arrived used Review by Gregg S

The plow I received (direct ship from King Kutter) had obviously been used/returned in the past but was sent to me as a new unit. It had tooling marks where it had been wrenched on, scuffed/missing paint, even some dirt and rust. The box it arrived in had a hole as well and some of the hardware was missing. Rural King customer service stepped up and made it right, but dealing with King Cutter seemed to be a long ordeal. Will certainly buy from Rural King again, but have hesitations about KK products going forward

For the most part well made product BUT it can be improved Review by G.Heydt

For the most part well made product BUT it can be improved Also,it DOES NOT fit a John Deere 1025R with a iMatch hitch. It isn't wide enough OR long enough between lift pins and top link pin. Just take the iMatch hitch off and install right on the 3 point hitch. When mine came the box was ripped open with BIG holes in two of the sides and the lift pins were missing but I have plenty of pins so I just used my own .Also, the picture shows that there is a square piece of steel in the middle hole between the two bolts .Mine isn't that way. I think it would give more stability if it were there.

Not right for me Review by Ray

Good product and Rural King was easy to shop and ship. Will order from them again.

The depth I can get on my L3301 is really only about 6 inches. I could not use this on my quick hitch because the pin spacing is too narrow. After more research, it seems this is designed for sub compacts but I didn't see that anywhere on the RK website.

I haven't tried the plow because I ordered this for the subsoiler to lay water line 18 inches deep.

Great for digging potatoes Review by Maxx

I bought this after years of hand digging potatoes. This thing is great for digging potatoes. I also used it to plow up some ground to expand my garden and it worked great for that. I am very happy I spent the money.

great Review by Richard Sellars

Recieved within days of order. I have a compact new tractor. Works great and well built. Best to use Fed Ex for your shipment. I also ordered fence shipped by Ellis. Still waiting on that order, placed at the same time.

wouldn't work for me Review by Robert Bentley

Comparable to other products of its kind. However, it did buckle the three point hitch twice when I tried to use it. No damage was done, but I couldn't use it. After research, I found other retailers that it had a 25hp limit on it(tractor size). My tractor is 45 hp.

Expectations Well Met Review by Cal

I'd been wanting a middle buster for a couple years to plow spuds, clean out ditches, break new ground for the tiller, etc. Been keeping an eye on Craig's List, ebay, local want ads, etc. but very little available for a good price...or at least a price much lower than what Rural King had on this unit. The fact that their unit also included a subsoiler chisel just made thier deal even sweeter. When RK advertised free shipping, I couldn't resist and promptly ordered one.

The only problem I experienced in the process was that the plow came without the bolts required to affix the moldboard/sub-soiler chisel to the vertical shaft. When I called RK however, the customer service rep with whom I spoke immediately contacted the folks at King Kutter who in turn promptly shipped the bolts to me in two arguements from anyone.

Upon assembly, I immediately set out to dig two rows of potatos. The plow worked perfectly and was very controllable for depth with the hydraulic controls on my BX24.

I'm sure you can find a competitor's middle buster with slightly prettier welds but the ones on this unit all appear strong and didn't break even when I sank the plow full depth to the horizontal 3pt hitch shaft...just to test it; pretty is as pretty does!

KK/RK's BX sub-compact middle buster appears to be a well-made product, a good value for the person who needs to use one a couple times a year on small acreages and mid-sized gardens.

What is the working depth of the sub-soiler?
Will this work on a John Deere 1025r? Most information and/or reviews only refer to Kubota tractors.
Need a ripper point,how much does it cost?
Will this product fit on a Kubota XB25 compact tractor.
Will this product fit my 1025r I match
Can I buy just the skinny ripper point?
how about a BOBCAT compact tractor model CT230 --- would the other model work better - King Kutter Middle Buster, Model# MB ? I need this for cutting some drainage ditches in and around a gravel parking lot.
