I have a 3pt 6 1/2' double gang disc, and am wondering the proper technic for disking new ground.

For instance, can I turn corners w/ the disc down, or will it cause stress on the disk frame or disks?? Is there a certain angle that is acceptable (say like a 45degree) to turn w/ the disc down, or do I need to run only straight rows. If I am doing a field w/ a rounded edge, can I follow the contour of the field.

Thanks for helping a newbie out.

You lift the disk on the ends or sharp turns.

Are you disking plowed ground?

No, most of the ground I will be disking will be orchard grass fields that, to my knowledge, have never been turned.

What would you consider a sharp turn???? I would assume a 90degree angle would be out, but would a 45degree angle be ok??

I have pulled one of those over many acres through the years. You need to pick it up on the sharp 90's and some of the 45's. If you have a long radius to follow even if it is a 90 it will be fine to leave it down. As far as following the contour of the field, that is not a problem. It is just the sharp turns that will tear the disk up. I usually "double" it the first time and then "single" it on the finish pass. By doubling" I mean overlapping the last cut and it will do a lot more cutting on the second cut. Then when you single it it will smooth the ground a little better. I like to have a heavy drag on the back to break up clods and help level the ground.JP

Most small 3pt disks are pretty light; it may not bust up the ground much unless you have real sandy soil. Plowing or at least a field cultivator would generally be best suited for busting sod. "Half lapping" like Jack suggests and "double diagonal" tilling work well also.

I have a double drag disc and split the field into two 'sections',and disc as if I was writing one continous big letter 'O' that is overlapped(kinda like writing practice a long,long time ago.I have to add some concrete blocks on the rear section to help her dig in.

You may need a couple of passes, the first one, discs are almost straight to cut the sod,next pass more aggressive cut, and so on.

I've also found N-S, then E-W discing helps keep the soil flatter.

Just stuff I've learned the hard way.....

Thanks for all the pearls of wisdom. Last year I was using a single gang disc behind an atv.....talk about taking a long time to bust up an acre field. With my atv setup, I didn't have to worry about putting torque on the disc, as it was a single gang and pivoted on the ball attaching the disc to the atv. I was concerned about the strain a turn might have on the second gang, and the fact that this disc is somewhat stationary on the 3pt hitch and is significantly wider that my other setup.

Again, thanks for you input.

With a 3 point disc,any turn more then about 10 or 15 degrees puts way too much stress on the 3 point hitch.

The point that everybody missed is that turning with the disc in the ground will leave unacceptable ridges that will be a bear to get leveled out. Lift the disc and make your turn. You will probably have to disc several directions to get that sod torn up.

I would plow sod to turn down the sod first. You will spend a lot of time getting any kind of depth of loose soil. I wouldn't disk sod with out plowing with my Oliver 1850 and the big wheel disk.
