Ripper or what?
I saw this ripper with V-blades in Nebraska, USA. How many
horsepower needed?? Can anybody tell more about it; like
make and hp. needed etc.
Re: Ripper or what?
CW, blade plows were invented in Nobleford Alberta Canada I
think (Noble Blade). Originally there were 2 blades per
wheeled implement. Many of these were pulled on a hitch
when used with crawlers (early 1950's). I have hardly seen
any in Canada in recent decades as they use chisel plows
with big sweeps. The blade plows are used a lot in the
winter wheat plains of the US (W Nebraska, Kansas, E
Colorado, Oklahoma and Texas) for plowing grain stubble and
summer fallowing where ground lies fallow (unused to store
up moisture for the following years crop). During the 80's
when I first went down that way there were several companies
building them. This brand was made in Cawker City, Kansas
and is now owned by Sunflower along with the FlexKing which
were green similar to the Noble blade made in Canada and
later sold as Versatile and Cereal Implements till it's
demise. You can see them in Agco's Sunflower site. There are
sizes that have 5, 6 or 7 ft wide blades. Power probably
depends upon soil and if you're using them to plow stubble
or undercut weeds and mulch the soil like a rod weeder in
summer fallow. Seemed to me that a 130-150 pto hp two
wheeled tractor was often hooked up to a 5 blade plow. Two
wheel drive tractors seemed to be used alot in Kansas and
other plains states where there were rowcrops or irrigation.
I would guess 25 pto hp per blade on rear wheel drive
tractors. That was quite a while ago.
Re: Ripper or what?
Just need to add that the idea of the blade is to undercut
the plant leaving alot of the stubble to stand on top of the
ground to prevent the soil from blowing away in the wind as
it did in the dust bowl of the 1930's when people could die
in their houses or get pneumonia from the dust storms.
Clouds would travel hundreds of miles into large cities like
Chicago which is not even near the plains.
There is little need to Rip or subsoil where there are cold
winters and enough frost going deep enough to raise the soil
and counteract compaction. Rippers are usually used in
southern areas in North America where there is little frost
and thus much compaction. You won's see them often in the
Great White North with or the northern plains with their
extremely cold winters.
Re: Ripper or what?
Redpainter, thank you for the very good and interesting
information about this implement !! And also other
information and comments on other machinery and implements.
You really have a good knowledge of farming equipment. I am
glad you are sharing your knowledge with us on Farmphoto.
Please keep it like that !!!

Re: Ripper or what?

Specifically, this is a Richardson 9x5' (45 feet) semi-chisel plow. The lamens term for this implement is "sweeps." The other posters are correct in their summation of its purpose and design, but to answer your question regarding horsepower, this particular machine will require at least 250 horsepower to pull the machine adequately, though this would be on the light end. We use sweep machines larger, 54', and we have tractors with about 360 horsepower. Also, four wheel drive tractors are most commonly used with sweeps as large as the ones in your picture. They are wonderful machines and have helped farmers for decades save precious topsoil. One poster mistakenly surmised that sweeps are used mostly where compaction is a problem. Let me clarify: they are useful for getting under compaction, but they are mostly prized for their ability to cut weed at the root zone and leave surface residue more intact than other machines would leave it. Let me know if you want any more info.
