Subsoiler

[78-79fordman]

I believe it's only rated for 40hp. I got it for $170 OTD on an impulse when I was picking up a few things for the horses. Outside of bringing the welds up to my standards, it's done everything it's been asked to, even things outside of its design. I certainly wouldn't pull it behind anything larger.

Fordman, you're really going at that field. Are you having drainage issues in it? What speed are you pulling at? Full depth?

Tractor supply told me there's was a 15-20 hp ..

Ya some of it has drainage issue ...

Speed first and second gear low . With m7040 in 4x4 didn't try it in 2wd but probley would do it fine . Only letting it idle at 1200 rpm in them gears . May could go faster don't know but at them speeds maybe I could stop it if I hit something . And ya at full depth far as it will drop on the 3 point . And not using the drift control at all . just let'n it eat

The m7040 don't even know its doing anything pull'n it . Can't really feel it . It just thinks its just a hair above idle rpm going across the field slow .

With a subsoiler, you want it adjusted so that it lifts the soil from the point in the ground. The idea is to shatter the soil by lifting it not ripping it. The shank should be running so the it is at an angle with the bottom in front of the top. With the point ahead and the shank running up at a backwards angle, you get then most lift and shattering of the soil. It will also pull easier that way. You don't need to go any deeper than enough to break thru the hard pan. To check that, take a bar or piece of rod and try to push it into unbroken soil. Then push it down into one of the subsoiled channels. If you have gotten below the hard pan it should push down into the soil at the bottom of the channel easily. Adjust your depth so you are just below the hard pan. Going deeper than breaking the hard pan is unnecessary. Also for maximum benefit, you should subsoil such that your next pass breaks up the soil touching the broken soil from the previous pass. I used to subsoil 1000 acres on a 2-3 year rotation with a 5 shank subsoiler on a 200 horsepower 4x4 John Deere and on heavy soil it would bring it to a stop. After breaking the soil up, it is amazing the difference in drainage and production.

I think it will be impossible for 78-79fordman to "shatter the soil" with WET SOIL on his tractor tires.

This is how we have to shatter soil around here

Ya some will some want for sure . the wet I would say I'm just cutting a groove .

And that mud on the tire I got to close to the pond . Lol thought I was fix'n to get it in its first stuck . But this m7040 does good in the mud doesn't bog down . But it doesn't have cast centers or loader tires . If it did I probley would have don buried it up . Lol

I would say where the grounds dry like here I'm getting the lift it should right ???
I'm its a good bit to me ..

Skeets, for some reason I had a feeling that's what I was fixing to see.

BAP, I have spent a month helping my neighbor subsoil wheat stubble several years ago. I used a 300+ HP tractor and a 7 shank ripper. I got to know that tractor very well, it also was very new and had more power than I was use to. You could always tell when you hit where they drove the semis and grain cart, it would almost bring that beast to a stop. Black smoke would blow and I would have to pull it up some and go over it again. Probably one of the easiest and most boring tractor jobs out there. Growing up on a farm, I have done just about all of them. Best part about it you never have to worry about hitting a fence.

Sorry BD I just couldn't pass that one up

78-79 Fordsman, the last pictures you show of the lifted soil is what it should look like. Even though drier soil works better, subsoiling threw the wetter soil will help it drain out even if it isn't as good of a job. You can always go back and do it again after it dries. Watch out subsoiling threw standing water, did that once threw some dips in the field that were holding water because the soil was so compacted. Worked great until the last pass and it was narrow. Turned out I was driving in the furrows from the two passes on either side and the tractor dropped in up to the frame and then some. 5 hours latter, 3 tractors, bulldozer with winch, and a skidder all pulling at once, the tractor finally broke free.
