I just finished plowing a few acres with a 185 and JD 4 bottom semi mount plows. The plows could use some new shears but they operate as they are.
My complaint is the plows, plow shallow on a crest and deep in a dip.... They get the job done just not consistent depth...
Traction boost is operational.... Depth control is all the wsy down. It functions that way on two different 185 tractors.
Headed back towards drag plows.
We do have hilly ground.

The ground is steeper than it looks. We only plow up hill. Dead head on the way back.leave a dead space every so often to prevent erosion...
Even tried a 2 bottom flip plow on a D17.
Still leaning on going back to drag plow. And weighting the tractor so draft control isn't nessasry...

The more bottoms you have (length) on a mounted or semi-mounted plow, the more of a problem this can be. It makes no difference the color of the plow or tractor. A pull type plow of the same number of bottoms might be a little better with the front wheels being closer to the front bottom. Engineering is usually always a compromise. To get one thing (more bottoms/more productivity) you have to give up something (depth control in rolling ground). I guess the solution would be a one-bottom plow at 8 or 10 MPH.
