I think the in-line has less ground disturbance (if residue is a concern)....and the V will pull a little easier, one shank starts the lifting process for the next.

If you are trying to get rid of compaction you can't beat an inline. If you want to cover residue, use a v. The inline will pull hard but is worth it in the spring when normal water ponds don't show up. We have nearly covered all our ground with our inline ripper at about 14 inches deep and it has made a big difference in drainage and compaction. It was a good character builder pulling 4 shanks with a 4450 at 4.5 mph but was well worth the time.

Northwest Ohio

This is our first year with a 3 shank blujet. Pull it behind IH1486 at about 14" deep, in wheat stubble thus far (used it on end rows last year after harvest). Really seems to do a better job lifting the our V-plow (JD90) ... seems like the tractor handles it better too. We've got the summer (narrow) points on it now .... you can see a lifting wave going thru the ground as you're pulling it. The V-plow seems like when it wanted to go deep, it would go real deep, and neither the tractor nor gage wheels would stop it (and eventually the tractor front end would get real light). The blujet seems a lot more of a controlled pull ... when it really gets pulling hard, you just start slipping more (but the front end always stays down).

Just seemed like we were trying to make the V-plow do too much over the years ... and it was a lot harder on the tractor than I'd like.

Subject: horsepower per shank?

southeastern ohio

Anyone know what would be the recommended horsepower per shank, with 2wd tractor. Would a 85 hp with good tires and weight pull a 2 shank. Would like to run several ends where too much turning around.

Subject: Re: V ripper vs. inline

If I am understanding the various tillage definitions correction, an inline ripper is a form of vertical tillage while a V ripper is a form of horizonal tillage.

With similar points installed on each, I don't see any reason for one to be better then the other in terms of removing compaction.

The V ripper will pull considerable easier.

I'm completely missing the horizontal vs vertical bit....the shanks are the same (or can be) on either frame style. The shank is what is doing the tillage, not the frame.

As a general rule or thumb, when you see the name of the author of the article that was liked in this thread I would strongly advise turning the b-s filter on extra high. I believed something he said once, but then I studied agronomy.

Am I right?

As for the ripper.

The inline will disturb less soil but still do an excellent job of fracturing. If you use an inline and it rains alot in the spring you will have a chance at driving on top of the soil. The downside is that they pull extremely hard, depending on conditions 40-50 hp/shank is a good starting point.

The v ripper types disturb alot of soil and can do an excellent job of burying residue. The downside is that if you get a wet spring you will have soup and you will be driving on the layer of undisturbed soil below where the ripper was operated.

I prefer the inline but then again I really prefer avoiding compaction and tillage as much as possible.

Southeast MN

which doesn't take much. 8-)

Inline versus V rippers were explained to me once that the inline will lift and disturb better because all shanks lift across the width at the same time when a V machine goes through each shank lifts on it's own not getting any lift action from neighboring shanks that are staggered behind it.

I haven't run either type, and like I said. Sometimes I get confused.

Subject: Sorry, my choice of words was poor.

The inline does a better job of fracturing but it doesn't turn over any soil. It just lifts it up and sets it back down. The lifting is what fractures.

On the V ripper the soil churns as it goes through the shanks resulting in sub soil on the top hence the name "sub soiler".

Hope this clarifies my opinion.

I'm not sure, and since our DSL is scheduled to go off in a few minutes for maintenance I'm not going to go back and reread the link, but I was refering to the so-called agronomist who is most often read about in the leading farm magazine which is not Successful Farming.

cropsey, il 61731

My vote on the inline vs V ripper is that they do about the same and the amount of disturbed top soil is a function of speed and shank type. I pulled a 5 shank dmi 2500 with winged points (350hp big a manure truck) and it lifted soil and left slots at 5mph and looked chiseled at 7mph. The earthmaster I run has the disk gangs in front so it's a little hard to see what's going on, but it's my opinion the configuration of the parabolic shanks is what lifts soil to the top. If I ran the 2500 shanks on the earthmaster it should run about the same as inline, but may pull a little easier since the lead shank would start fracturing for the other shanks rather than everything at ounce. Naturally, in line rippers are in style now and are tidier behind the tractor, but I would guess an older v-ripper with different shanks would work just fine.

My 2 shanks,

PS: "He" has impressed many folks including magazine editors and folks I know... He is not wrong - a perfectly even stand is always better - getting it that even is the problem not easily solved. Typical of this type of salesman, he is good at pointing out the problems and making it sound like the solution is easy and that he has the solution for a price. I bought the dvd and it's a pretty nice demonstration on scouting and detailing various problems - reinforces what you generally already know. He points out some problem fields where probably there is more to the story than "the farmer screwed up" - he doesn't mention things like it may have rained everyday in April and it got just dry enough to plant May 10th so the guy/gal planted, but his tillage tool had trouble with the damp residue and didn't stop because it was threatening rain the next day. I would sum it up as he is the guy saying "never work ground wet and wait for the perfect conditions" - even the Bible says he who waits for the perfect time to plant will not plant - the challenge is making the best choice given the constraints we work with (soil condition, weather, calendar) and Mr. Ferrie doesn't go there (perhaps in a later article called "What to do in real farming conditions"). Frankly I was happy to find out my old earthmaster does somewhat fall into the popular 'vertical tillage' category - I was concerned I was getting to out of fashion.
