x3 on this advice. Good place to start.
WOW!! Thanx everyone. I am going to the land this afternoon and will be there the next few days. After I get through with my keyboard work I will study these responses. I learn so much by listening more and talking less. I had wondered what those **** holes were for. The plow is rather straight. I have seen videos on EA.com where the moldboard is at almost a right angle to the plow frame.
In answer to a couple of questions, I have cut about 20 strips in the dirt a 100' long. It is a good, dark, not to full of clay, breaks up easily in my hand. I was told the coulter would not work because of the links on the inside of the lift arms. The B7510 is class one. One thing I saw was a depth wheel, since the B7510 is a neutral float or something, like most compacts, I was told. The wheel keeps the plow from going to deep and stopping the tractor cold, which mine did.
I figured out I had to keep my speed up, so I am going at a pretty good clip.
Kind of funny, I did cut a furrow and it flipped, the very first cut I did, have not been able to repeat it. I saw a video where you lift the left side, if you are sitting in the tractor, 6" and then level the draw bar. Was that wrong? One last question, could the plow from TSC be to big? The one bottom plow on EA.com is almost 12" skinnier at the draw bar. They say for a compact tractor.
