The day after Christmas I was able to finish up my fall plowing! What a change from last year -- I have 21 of our 26 acres chisel plowed this year. I use a tool bar with five heavy spring shanks spaced around 16 inches apart, with wide sweeps and go around 10 inches deep. This leaves the field in ridges that work well for winter. The crop residue decomposes well and the soil is mellow in the spring. It takes around 10 hp per shank to pull the tool 10 inches deep at around 3.5 to 4 mph. I have an old 2240 John Deere that is around 50 hp that works well.
I feel we are off to a good start for next season with most all the ground ready for spring!
