To all Master Plowmen.
(And anyone else that has had good or bad experiences plowing) (I posted this on Implement Alley also)
This question has been bugging me since I started plowing a few years ago. How does rear tire size and furrow width correlate? Example-- My bigger tractor (1755 Oliver) has 18.4-34 rears on it and I pull a 16" four furrow plow. So the tire is about 2-1/2" wider than the furrow. Given a small amount of space for steering and sidewall clearance, say 1" on the land side of the furrow that makes 3.5" of plowed ground I'm re-compacting with the rear tire on every fourth furrow. Isn't this counter-productive? Not to mention making it hard to set up the combination to plow correctly ?
So the question's are-- Is it better to plow with a plow that has a furrow width greater than the rear tires or doesn't it matter to anyone? In my case it would have to be a minimum of 18" bottoms with 20" preferred?
The reason I ask is I'm going to be looking for good used tires for my M this year and since I have 14" and 16" plows to use with it will it make a difference as to whether I find /look for 15.5's, 14.9's or stick with 13.6's? My plows are two three bottom 16" #8's or a three bottom 14" JD. I have a four bottom 14" #8 but I've been told a M won't pull it which I totally agree with since I pull a 4-16" with my 1755 Oliver and have hit the occasional hard spot that made it grunt.
Any thoughts on tire width vs traction vs bottom width would be helpful.
What's the expert opinions here?
The factory equipped the tractor with 13.6's for a reason I guess. But is that reason relevant any more? Aren't traction and flotation King now?

Today's Featured Article - The Ferguson System Principal An implement cutting through the soil at a certain depth say eight inches requires a certain force or draft to pull it. Obviously that draft will increase if the implement runs deeper than eight inches, and decrease if it runs shallower. Why not use that draft fact to control the depth of work automatically? The draft forces are
