Sub soiler for compact

[roamerr]

OK -- question:

Why do I need a shear pin on a subsoiler if using with a Kubota BX? I use a subsoiler like the TSC one and if it hangs on a root or big rock the BX will stop moving and just spin. On a large tractor the shear pin may be needed but on the BX I do not see the need.

Yes, that one is much longer than the combo one, and I think it's too long for the smaller B series, and BX series tractors. The "yellow" middlebuster is OK though, and stronger than the combo unit so I'm just going to add a subsoiler blade to mine.

How many Horse power is reccomended for this subsioler. I have a Mahobdra 3325 and it is rated at 35 hp. Is is enough to break up the hard pan about 20 inches down.

Which one? The county line? There's a link on my post, I belive it's 50 hp.

I have one of the tractor supply "subsoilers" but don't really consider it to be a real subsoiler. It in my opinion would need a larger foot that will buldge the ground around it while running about 24 to 36" deep. Takes about 75 hp per point. Would make a very good parking brake for a compact tractor.


A chisel plow can run 12" and I don't consider that to be subsoiling either.

The ones I've looked at at TSC don't measure out to allow the sub-soiler blade to mount to the middle buster, without modifications but it does appear that you can bolt on the middle buster plow to the sub-soiler. I was going to go buy the sub-soiler today, until I saw this post. I know they change the spec's and construction on these things from time to time (in fact, my local store has two similar - same stock # -, but different sub-soilers sitting on the floor right now - one's about 4" longer (deeper) than the other.
Does anybody have first hand experience with this "conversion"?

I went there first to buy the "official" combination unit, but it's way too small, maybe better suited to a "sub-compact" tractor.

Well, it is not "real" subsoiling, but the object is often to just break the "tiller pan" which may be down there 4"-8". It seems to be the best we can do with our small tractors.

You are right about the subsoiler blade not fitting the middlebuster. I was just thinking of cutting a piece of 3/8"-1/2" steel to fit, and drilling the holes to match those on the plow blade. The problem I saw with the full size subsoiler is that the attaching pins were around 25" off the ground, and I doubt my Kubota B2620 would lift the thing more than an inch, or two. Of course that allows it to go deeper in the soil if you can lift it enough for transport. Now if we could combine a design for a shear pin with a way to pivot it out of the way............. it would be worth modifying.

Good point. Since I've never operated one of these, my question is how "vertical" do you operate them? I assumed looking at it that the "main spar" would be set at some (??)significant angle to the ground surface, which would "use up" some of that 25". TSC lists these as "12" maximum ripping depth". Am I thinking right or not?

I pull mine with the mast vertical and as deep as it will go, the foot has the proper angle built in.

Would somebody mind posting what the tooth angle and what the shank dimentions are on a (single purpose) sub-soiler?

Thanks.

I'm still waiting to see how the shear pin part works as my home built subsoiler has been pretzelified twice now. The pivot is easy: Just add another set of ears for the top link on the back of the implement. Pull the top link pin, roll the top of the implement forward, and attach the top link to the ears that are on the back (now the top).
