Hi All.

I am looking for a 3PH single shank ripper/subsoiler with a working depth of at least 28", preferably 30" - 32". There's stuff out there on Google that says it is a 28" to 30" shank , but with research I find the working depth is only 20" - 24". I have easy access to a 50 hp 4WD JD for the ripping.

It will be relatively light usage. Based on a detailed soil study, I need to break up a rooting zone barrier (topsoil to hardpan horizon) at 27". This is a one time rip for 5 acres of vineyard in-row preplant preparation. A bigger multishank unit is not useful since I need to rip on the row (8 feet apart), so it's one at a time.

I guess maybe part of the issue with a longer shank is the 3PH travel distance - too long of a shank could not be fully lifted...??

In order to get enough clearance to lift it above the ground it would need to be set back farther the the run of the mill subsoilers in your link. If designed with good use of geometry this would also reduce some of the loading on the top link. I would also recommend you consider the ones with the parabolic shank as I think these are slightly easier to pull. You will need plenty of ballast on the tractor to pull a subsoiler this deep.

Do you have the facilities to make one the size you need? Years ago, we made ones for Cat D8s for ripping orchards. They were 8 ft x 2 ft x 4 in.
If you can get a tool bar, then you could make the size you need and not have to hunt all over the country to find the right size.

I agree that parabolic is probably a better chouce for the working depth that I need. I have access at work to a plasma cutter and mig welder, so building one is an option.

If I were to build a parabolic shank, I guess I would need to cut several pieces out of plate 1/4" to 3/8" thick each, and laminate them together?

Kirboid,

Tufline has a 28In. single shank sub-soiler out. They have a 32 In. sub-soiler model out with 3 shanks. The 32in shanks that they use in the triple shank series I think will change over.

Take a look at the Tufline series, and if your interested I will see about a 32 In. single model.

That is really deep ripping. Unless you soils are really loose, I don't see how a 50 hp tractor will pull it. I pulled a single shank with my JD 5300 MFWD, loaded tires and FEL. I could only go about 14-16".

I had seen Tufline the 28" single shank but it appears it's working depth is around 24". If the shanks are interchangeable, and the factory would sell the single toolbar setup with a 32" shank, that would probably work. I'd be interested in a price on that.

So you think my Case 33 hp compact won't work either, LOL! I agree 50 hp might not be enough hp/weight. I can give it a try, if it doesn't work, I could try a double pass. Obviously would take longer, but I only need to rip about 13 rows 400' long each, so it's not a big deal. It will take longer to accurately layout the rows than the actual ripping!

Worse case, I'm renting 15 acres for hay to a guy who has big iron, I could ask/pay him to rip it for me.


Thanks,

Kirby

I own a Tufline 1S-24 and use it with my JD 3520.

This unit has a 24" shank.

I can only pull it in 4WD, and the max working depth is around 18". As you pull the unit through the soil, the soil tends to mound-up at the top of the shank under the toolbar, and this prevents the shank from going all the way into the soil. Might be able to get another inch or three deeper on multiple passes.

The unit is rock-solid, and the shank is bolted-on and has a shear pin, so it seems like you could ask them if they can make a unit with a single 32" shank.

However, ground clearance on the 3pt with a 32" shank may be the limiting factor on small tractors.

Best of luck!

I have pulled a 1S-28 Tufline to the max with a 8000 Ford (100 HP +) 2 wheel drive and in dry clay based soil, it was all I wanted. Ken Sweet

Kirboid,

I got the costs of changing the 28 In. shank out to go with a 32 In. Here is a link to the page with the price. I currently have a Tufline name brand coupon discount going on any of the Tufline equipment. Take the price that is showing on the page and with the coupon it would be $1,197.95 + Shipping.

The change over to a larger shank added about 20 lbs to the unit.

If you need any help, please feel free to call me.

Thanks,
