Making Middlebuster go deeper

[bcarwell]

I have a Kubota 7500 and a new Middlebuster from Tractor Supply. Used it for the first time today and the deepest I could make it dig was about 8 inches with the 3PH lowered all the way.
Could somebody tell me how to get it to go lower ?
I looked in the Kubota manual and there are two holes on each horizontal link/lifting arm. If you hook the lifters to the holes which are closer in towards the tractor you get more vertical movement of tools connected to the 3PH (and less lifting capacity). But just eyeballing it, even if I use these holes which are closer in, it doesn't look like I'd get substantially that much more vertical downward movement of the Middlebuster (though I'm certainly game to try it). I had no trouble digging down the 8-9 inches but it appears I can't go any deeper not becaue of the soil or the Middlebuster, but because there isn't enough downward travel of the 3PH.
Thanks for any help.

I think you should change the angle in which the furrower enters the soil my manipulating the upper link by extending it out. That will cause it to dig in more agressively. I know I can do it with mine but I prompltly use traction as I have turf tires.

I don't think changing the angle of it is going to help due to the limiting factor is how low the arms on the tractor will go. It sounds like it is time to drag out the welder and either extend something, or change the mounting points to allow it to go lower. The drawback to that is making sure it will still raise the bottom high enough to clear the ground when you want to transport it to the next spot.

I agree with this aprroach. Remove all implements from your 3PH, and watch your arms drop all the way to the ground. If they do, then you need to play with it to find out what angle to adjust the plow.

Are you certain that the 3pt lower arms are in the float position?

I have a B7510HST and the KK middle buster/subsoiler combo from TSC. This time of year with rain-softened soil, I can get the MB at least 12 inches into the soil.

Last week I was digging trenches for PVC lawn sprinkler pipes using the subsoiler frame with a 6-inch-wide chisel plow sweep that I got from Agri-Supply. Had no trouble getting that sweep 12" deep in the ground and holding it at that depth with the 3pt control. In the float position, that sweep was digging about 16" deep.

What p/n is the 6" chisel plow sweep?. I looked at the Agri-site but didn't see anything called a "chisel plow sweep". I'm looking to buy the same combo this spring for trenching

What is the purpose of needing to go deeper than 8"? Any pics?

Hope this helps.

Here are a few photos of the 6"-wide chisel plow sweep that I attached to my KK middle buster/subsoiler frame. Fortunately the two holes in the sweep align OK with the holes in the subsoiler frame.

You can see from the dirt on the vertical support that the sweep pulled the frame down almost to the horizontal support that carries the pins for the 3pt lower arms.

For sprinkler pipes, 6-8" depth is enough.
I also use the sweep to dig trenches for water lines from the well to several sheds that I've built recently. I like to get these lines 12" deep.
