3 pt single shank sub-soilers

spruce Deere · Mar 4, 2013

O.K folks, here is the plan..... I bought a nice and heavy 1 thick x 4 wide steel strap 42 inches long for a subsoiler shank, price-$34.25.... The rest of the material will be of scrap metal that I have accumulated. Gunna be a cross kinda looking thing between the frontier and all the county line/kk/LS/ tarter things.

It will be able to go 24" deep, no shear pins, built heavy and ugly and I doubt It will ever pretzel..... If the mood strikes me, I just might paint it JD green when finished cause I have a little left.

Yes I will TRY for some pics, I'm generally not good with that when in the heat of a build, but I will try

I have considered making one myself as well, we have enough scrap steel here at work I could get it done pretty easily. I was wondering about the 1" steel too, but was concerned it might cause more resistance over the 3/4" that I usually see. I don't think it would be a huge deal, and probably worth it for the added strength and weight (it will be that much more fun to wrestle while hooking it up

)

It'll take some grunt to pull the Tufline, even the single shank. I pull the two shank with my 7610S NH and the diff locked, and can still lose traction in the right ground.

Very true!

I have a JD 3520 (37hp, around 3700lbs with FEL) and pull the Tufline 24" single shank with lots of effort. I've read that the curved shape of the Tufline sub actually makes it easier to pull through the soil. I can only pull it at max depth in MFWD, and only when the soil condition is optimal. I need more weight.

Best of luck with the construction! Be careful without a shear pin.

We've twisted up the KK subsoiler when a weld broke loose. Never had a problem with the old Dearborns (Dearborn 10-89 Subsoiler - Owner's Manual) which are common at auctions around here. I think mine was $20. These have a shear pin to prevent damage. Fred Cain makes a copy of the old Dearborn, but I don't know the relative quality.

My brother has a subsoiler that looks like the Dearborn. He's had problems with it folding up under the tractor when he raised it. Was this also a problem with the Dearborn? Is there a remedy for this?

The LS and deere brand subs I have been look'n at have the 1 inch thick beam also. They are rated to 40/50 hp also.

I am shooting for an non-pretzel build, and its gunna be a little hard to form one from that thick of materia and good welds and proper usage with my 790. After looking at all the pretzeled lighter ones here on TBN, looks like some poeple tried to turn a corner with the implement still in the ground while at full depth.......:confused2: and some subs looked like the welds were just junk from the factory and just pulled apart with some use or finding a root, rock or something with a little resistance.

I sub-soil slowly, just in case of an non-moving obstical and there is more power in the low range, and ALWAYS lift implement out of ground before a corner, then turn the corner

How deep are you going with this and what type of soil do you have?

Will the middle buster style tater digger go 18" deep? The ones I have looked at at the local TSC don't look like they would go as deep as an actual sub-soiler is intended to operate.

-----------------
To Oldnslo....... Yes the middle buster you see in my picture will pull just about full depth, in garden type ground.

------
To the poster in #31....... Nice score on the steel. That seems a good price....
But make sure you have enough 3pt movement to keep a 24" deep implement above ground when you need to.....\
Be sure to post pictures of your build.
Good luck

It will do that due to the pivoting top link attachment arm I don't mind it. Just reach back and pull the top towards the seat (may need to attach a rope) as you lower it to the ground.
I suppose you could put a put a couple of washers between the top arm and shank and tighten down the bolt, but it really is designed to pivot.
