I recently bought a JD 8210 and am thinking about a ripper to pull. 4 to 5 shanks, was wondering what brand in the best. Do not want a disc ripper, want to leave the residue on top. Just the best in line with a single coulter in front of each shank. Also is it better to go with a 4 shank and go faster to shatter more or 5 shanks and go slower, max depth would be 12-14 inches do to shallow field tiles.

If your only going to scratch the surface by just a mere 12" do you really need a ripper?
I think a chisel would do what you want with that shallow of a depth.
Not going to reach a hardpan and do much at only 12" are you?
Personally, Stay with an odd number of shanks. 3, 5, 7,.. etc etc. Then go with a number that you can pull and not lose traction in a hard pull with a very hard soil base but when you hit the looser stuff... then you can bump up gears and go faster.
How many hp is an 8210?

Ground too heavy for my old chisel to go that deep. Have an international 6000 with extra big springs and straight points and still the shanks just spring up. I was thinking a 4 is what i needed and has to have springs too many rocks here.

This will all depend on where you find the hardpan and how thick the hardpan is. K-State extension has done some work around here and in NW Kansas. Hardpan has been found at the 10 to 12 inch level with a thick ness of no more than 2 inches. Their suggestion is to rip about 2 inches below the bottom of the hardpan. Deeper ripping is just a waste of fuel. That comes from the powers that study this type of thing. |

If there is no more hardpan under 12", then it should be like a hot knife through butter under the hardpan ripping and not anymore resistance. Also.... if the tips are down in looser dirt below that hardpan, it should not wear them as fast as if they were close to the hardpan. Again, I am never impressed with k-state findings. |

We pull a 7shank blue jet, and it will bring an 380 HP 4wd to it's knees. Usually pull it 17"-14".  And this is what happens when you pull it with to much HP.. Blue jet need a little more in the BEEF department...   |

Will be a 3 point unit so I won't have that problem. I guess I will start looking for 4 shank units. Do you like the rest of the blu jet? Need spring rest up here.

Yea we like it. I do know a few around here who had spring trips this last year, and they couldn't keep them from tripping. BUT we were unusually dry and the ground was like a rock.

My personal opinion is whether to go 4 or 5 shank will depend as much on the horses as how you plan to till. 5 should run your middles, 4 will be ripping in row. No big deal either way, just changes the way you drive. Here we subsoil every year, and it is going to subsoiling spring and fall trying to get this land to hold and release more moisture. Obviously our land is not as heavy, sandy topsoil and red clay subsoil, but I would say here straight points are pulling about 25 horses a row, shatter wing points take about 40 a row or so to pull, can cheat some with 4 wheel drive, but here we seem to pull around the 4 MPH mark, lots and lots of fuel, you and your fuel pump will be best friends.

Here in our clay soils, I run a Progressive inline ripper. 8 shanks on 30" centers at 4.5 MPH with a tractor with 400 engine HP= 50 HP per shank. We run 12 to 14" deep with this tool.
Our plow layer is just below 10 to 12 inches deep. It is hard to get any coulter chisel under this depth when chiseling corn stalks. In our soils the inline ripper is much more efficient when the goal is to undercut a plow layer and fracture without covering as much residue.
I also have a 9 shank- 13.5 ft- Krause Dominator that I use on my corn stalks that aren't going to be no till soy. Great tool for shattering, slicing, blending stalks, and leveling. The Dominator would be a poor tool to try to go a true 12 to 14" deep with the shanks on 18" centers though the tire, tractor, and fuel dealers would love it if I did.
In my area, i have met a few that suggest they are chiseling 12 to 16 inches deep with a coulter or disc chisel. A quick check with a tile probe or steel rod after the soil is weathered, settled, or leveled quickly proves that they are measuring differently that I do.
The depth of any plow layer will be determined by past tillage depth. In heavy clay soils it is easy to feel with a tile probe.
All depth measurements are in firm ground. Chisel plows fluff the soils up so much that the depth measured to the top of the fluff would add 2 to 4 inches to the depth.

We have had an Unferverth, DMI, and now a Krause and in that order. IMO the Krause is the heaviest built of them 3, and also pulls the hardest. I don't care for the Unverferth at all, and my biggest beef with the DMI, was that the no-till shanks have no wear strip on the shanks them shelf. The DMI points are somewhat expensive, but the shanks are farily cheap compared to the point. However in 2010 I wore out a new set of shanks and points in 600 acres on a 5 shank. Our Unferverth was a 5 shank, and I pulled it with an 8310, and that was all it wanted. I pulled the DMI was a 5 shank and our MX 275 handled well. Now our Krause is a pull type 7 shank wing fold, that we normally pull with our 425 hp 4wd, and dad complained all fall about needing more tractor. I pulled it 1 day with the 275, and the wings folded up, so a 5 shank, and I was wanting more tractor as well. The Krause has the no-till points, put it will disturb the ground more than the DMI did.
