Correct set-up of plow and disk

gregarpp · Mar 22, 2011

I have an old Dearborn 2 bottom plow. This came from a ford 9n

It has 2 plow points, one rear drag steel wheel and one front coulter.
I have been just hooking up level and letting it rip.
Not sure if it is actually working correct.
Is there a proper setup I should be doing?

Also bought a dearborn disk last fall.
Again just hooked it up level and had at it. Seems ok to me.
I think I need more weight on the disk. I have some slabs of old concrete? Or is that too much?

With the plow, it is important that each bottom
cut the same depth. Being that the right side of
the tractor will be down in the furrow, this means
that the plow should look "crooked" with the right
side high when the tractor is setting on level
ground. To get it set initially, run the left
side wheels up on blocks that match your plowing
depth, usually around 7-8 inches. Then adjust
your lift arms and third link to get the plow to
set level on the ground. Once in the field you
may need to tweak things just a bit to get it all
leveled out. The wheel spacing is also very
important so that the two bottoms cut the same
width.

With the disk the most important thing is for it
to leave a level swath of ground with no ridge or
furrow in the center. This is done by adjusting
your third link to set the pitch. You will find
that you'll probably have to tweak this now and
then to match conditions and driving speed. Many
disks have adjustable angle gangs that can effect
the leveling but on my own disk I always leave
them in the most aggressive position (steepest
angle) and level with the hitch setting.

Save yourself a few bucks and read this. It is a PDF file so you can save a copy and print it out.

You are correct sir. Make sure when tractor wheel is in furrow and plow is in the ground that it is running level from side to side and front to back. As far as depth is concerned, a plow works best when you go half as deep as width of moldboards ie. 12 inch mold board=6 inches deep. 14 inch=7 inches deep and so on. For the disk you are also right. When in the ground disking it needs to be level from front to back. On a tandem disk if you notice your front gangs are throwing more dirt out then back gangs are pulling back then you need to tweek it a little bit deeper in back. Likewise if you notice a ridge in the middle behind you after you pass then tweek front gangs a little deeper. After you get it fine tuned your field will be level except for the furrows left from outside disk blades on back gangs.

Spent many an hour in the tractor seat plowing with 3pt and semi
mount plows. Best advice has already been given..read the
appropriate manual throughly. One caution, most manual based
adjustment have the top link too tight and the 3pt plow tends to
run on its nose. Extend the top link length a bit so the rear bottom
is a fraction deeper than the front. The result will be a cleaner
looking plowed field as the soil will turn over better and the plow
will run easier through the soil when the plow is not on its nose. .

With a 3 point plow if they are set right the top link won't have any pressure one way or the other on it most of the time when pulling.
