How to adjust a turning plow and tractor

By

John Deere PlowNo matter what tractor you have, the initial tire setting for a 12 inch plow is 23 1/2 inches from the center of the draw bar of the tractor to the inside of the right rear tire. 14 inch plow is 25 inches and 16 inch is 27 inches. You can compensate a little if you are off on these measurements by sliding the plow A-Frame on the plow crossbar.

Once you get to the field, lower the plow and make 1 pass, plowing about as deep as you need. Then the second pass, let your right rear tire drop down into the furrow, lower your plow and start the second furrow. Now, get off the tractor and adjust your right leveling crank assembly on your tractor 3 point until the plow is level with the field, left to right. Next adjust your top link until your plow is level with the field front to back.

Now, plow this furrow to the end and on the 3rd furrow fine tune your plow again by repeating the last procedure. All plows should have cross hitch bars that have the right pin down and the left pin upward (standing behind the plow looking forward). This offset is approx 3-4 inches and is built into the plow.

In extra hard plowing conditions, you can loosen you cross hitch bar clamps and rotate it maybe 10-15 degrees to the back and if the plowing is easy then you can rotate the cross hitch bar the opposite way 10-15 degrees. By doing this final adjustment, the plow will do its best job with less strain on the tractor.

When a plow is set correctly, It will follow the centerline of the tractor perfectly without your riding the brakes and it completely turn over the soil.
