plowing and wheel space ???

I will be plowing with my 460 Farmall this fall and am curious as to figure out what i need to have my rear tires spaced at. I will be pulling a 3pt. 2-16 plow. Is their a math solution as to figure out what my rear wheels need to be spaced at? Thanks in advance!
 
Someone will come up with a formula, but basically you want the right rear wheel no more than an inch or two from the axle casting. You can move the other one in to match if you want to but it isn't necessary. This works for a disk plow. I have never used a moldboard, except maybe once on a JD 3020.
 
The full 16" cut of the first share is measured from the landslide to the tip of the share farthest away from the landslide. This tip should be very near the furrow when the right wheel is in the furrow plowing straight. Stopping with the plow in the ground, and digging a little will let you find it. The vertical position of that tip is also important as this makes the depth constant on each pass. Adjust the wheel spacing so the first share cuts full width. Jim
 
Jim explains it pretty well. I was taught to add 2" to that distance to allow for side to sode movement in the furrow. for 16" plow the measurement would be 18".
 
2" makes sense, because otherwise your tire would be rubbing on the side of the furrow all the time, OR, your front bottom wouldn't be making a full cut...
 
Our tractors always ran with the sidewall at the furrow cliff. From trailer plows on out SH and M, to the FH 3-14 on the 350U the tire was on the left side of the furrow, running there as a matter of convienient straightness. Jim
 
Centerline of the tractor to inside of right rear tire should be 27 1/2 inches. If plowing deeper than 8 inches add 1 inch to measurement. Do not use swaybars or anything to keep the plow from moving right or left. It will stay where it belongs if the plow is adjusted correctly. When its in the ground it should set level right to left, and front to back. If the cut of the furrow is to wide or to narrow, there is an adjustment on most plows to point it to narrower or wider cut.
