cheluIS, no problem with your background. We welcome all here. Helping others is what we like to do best, so ask away when you feel the need. None of us were born with knowledge...we ALL had to learn.
One question on your plow....the metal piece in front of your plow's leading cutting edge....ours normally has a coulter wheel to slice the ground ahead of the share. Yours looks to be just a flat bar. Seems that would create a lot of drag as well. If you either removed it, or replaced with a rolling blade wheel, that too would help with plowing ease. Or am I seeing wrong on what that piece of metal is/does?
Also, when moving the plow to the right...you may actually need to overlap the last furrow some, as there is usually flex in the plow which kicks the plow a bit more to the left under a load. You will see if it flexes once you get it close.
