Hello; Challenger was making the old D8’s look completely inadequate! I know the soil composition and implements were different but damn! Can anyone tell me what model those Komatsu machines are that are all hooked together? Now, that is a plow! Two meters deep would be over most guys' heads. You will have to show us how you prepare the plowed land for use. We/I would like to see the steps it takes to make it suitable for planting and also find out what kind of crop you would plant on this land. Farmers use the same plows year after year. When you plow a field to the normal depth (6-12inches) for years a "plow layer of compacted soil" develops in the bottom of the furrow. This layer blocks drainage. Depending on the crop it can even block the growth of roots. There are several ways to correct this problem--deep plowing is one of them. No till is another. With "no till" you stir up the surface with a harrow or just seed the crop through the stubble left over from last year.
