Never heard of these before. Been looking for a ripper. I was thinking this might be the cats meow with a disc on the front and rear. Front to shred trash. Rear to smooth up the dirt boulders brought up. Anyone had experience with a Laney? They a good machine? 2nd question... This one in the pic is 21 feet wide. Rigid, no wings on it. Would my 8870 have enough snort to pull this with 350 hp? Guy that had it before pulled it with a 9X20 deere (can't remember the size) and said he was rated at 450 hp and it played with this machine. I'm wondering at 100 hp less if my 8870 will have what it takes to manhandle this machine. Appreciate some input on this. Thanks. Attachments:

Can't help much about your question on the manufacturer, but I have looked at Krause and Sunflower units like that. My reading indicates you need around 10 to 12.5 HP per foot. As you know, depth and soil types being the key to HP requirements. The only thing missing on that unit is drag harrows to finish the smoothing.
I am considering a 20' width for my 8570 (rated 250) so you should be good. May even be able to get up to 7mph with yours.

Thank You Wf.
I was doing some looking at pictures today of other units.
Now Laney, puts a set of discs in front and behind the ripper shanks.
I noticed sunflower runs two set of disc blades like a disc and then runs the ripper shanks behind that.
I seen both variances today depending on who the mfg was.
I like the Laney angle. Shred up the trash and stubble before it balls up in the ripper shanks and then let the last set of disc blades help break up the dirt clods brought up.
What is the theory with sunflower using basically a disc in front of the shanks? I seen a setup that even had a drag harrow behind the Ripper shanks.... Looking at what I had been working with lately doing some ripping, those harrows are about worthless. I could see more purpose with a crumbler or maybe a set of tredders but I can't see where the harrow does any good at all.
I guess I just don't understand Sunflowers point of view on this.

The sunflowers I have looked at had disc-ripper-disc. I agree about the disc-disc-ripper being a WTF. Other manufacturers have it that way too. I am starting to like the JD 510 or 512 as a d-r-d unit.
Next summer I am hoping to find time to take the shanks from a Krause ripper and put them on an old sunflower 14' disc and see how it works. If I like it, I will spend some of those large government handouts getting a properly built unit.

I missed the mark on HP requirements. Here they are from JD: 5 -> 182 - 275; 7 -> 260 - 385; 9 -> 338 - 495

Must be a here vs there thing, but I think the disk/disk/ripper is the way to go with continuous corn. It chops up the stalks better so they don't plug/ball up thru the rippers. The Sunflower we've got has some kind of leveling contraption on it and seems to work well...all you need to do is knock the clods down and the ridge left by the rippers.

You better leave that thing in transport if you are expecting to pull it with a 8870

The 8870 I think , uses a newer version of the 619 engine ? If so , unless you have some easy pulling ground it AIN'T gonna pull it !! The 4311 Sunflower 7 shank 24 inch spacing ,mentioned above , is pulled by a 8960 , a good 385 hp maybe more , and in good old Illinois Black Gumbo 11-12 in deep , C2 is all it will do 5.5 -5.8 mph . Lighter ground we can run B4 about 5.7 -6.2 mph . In the heavy ground around here all the 7 shank disk rippers are pulled with 350 - 400 plus hp .

Nobody said you have to pull the damn things at 5 plus mph to do a good job.
The whole idea is to rip up and break up the hardpan. That can be done at 3 mph. As long as I have traction... I can pull it. Makes for a longer day but I'm already figuring that in.
If I hit soft spots that don't require so much pull, I can go faster. Main thing with ripping... it isn't speed, it's traction. If I can keep from slipping, I got it made.
I pulled a 5 shank for a lil bit this fall with a 7140 2wd magnum. In the really hard heavy stuff it was under 3 mph. Still broke the pan up. What I was after.
