Leveling a JD F125 plow

I have a JD F125 four bottom plow. I put new shares, and shins on it, set the tire spacing according to the manual. Then I set the arms and links accordingly. Took it in the field and it worked pretty good. The top link wasn't tight while pulling, it was jingling around the only problem I have is that the rear seems to be running a little higher than the front. I measured and its about an inch and a half off the front depth. I had set the rear wheel while the plow was on the ground and had it half an inch off the ground. My question is to get the rear running at the same depth should I adjust the rear wheel or the toplink. I stopped the plow while in a pass and the rear wheel seemed to be pressing rather hard, not riding freely. Thanks

Let the top link out a little at a time until it suits you. The furrow wheel and a long LANDSLIDE are to keep the plow from trailing sideways Thus the term LANDSLIDE. The furrow wheel if you notice is on a slant in order to ride against the unplowed side of the furrow.

The operators manuel for my JD 3 bottom mounted plow says to lenthen the top link if the rear bottom is not plowing as deep as the front and to shorten the top link if there is trouble with the plow entering the ground. The tail wheel should be ajusted to the landside just far enough to take the major side draft off the rear landside and down far enough that you can just slip a fingertip under the back of the landside on the rear bottom when its in the furrow. John Deere has operators manuels available for your plow.

The tail wheel seems to have alot of pressure on it so I think that is what is keeping the rear up higher than the front. I have the arms and links set according to my manual and while pulling the centerlink is floating in the pins like it should. I'll try moving the tailwheel first and then maybe tweek the centerlink slightly if necessary.

Yes,

But, aren't you misunderstanding that?

What they are saying is that the center link "could be too short" and holding the rear up. In this case, it needs to be lengthened to the point where it "floats" on it's pins before all other adjustments are made.

Really doubt that John Deere is gonna tell you to "push" that rear bottom in the ground with the center link. Just doesn't compute, as that is a darned good way to break/bend a center link while using any sizable plow.

Or, is this one of those little garden tractor type plows?

If the top link is short the plow is rolled ahead on the lower links so the front is low and the tail is high. If you get the link to long and drop the tail to far the pionts are basicly aimed upward and tend to ride up out of the ground. The operators mauel gives recomended starting lenths of 21 1/2 inches from pin center to center for lift links and 24 1/2 inches for a top link lenth pin center to center. Those numbers are for setting up my 810A plow on a JD waterloo tractor. It only take about one turn to make a big change and its not realy forcing it down. It alows the suck of the rear bottom to pull it down where it runs level and easy without a lot of preasure on the top link lke you said.

The center link is only used for lifting.

While the plow is in the ground and for all intents and purposes, you can take that center link off and throw it in the weeds.

"Jiggling" around in it's pinholes means it is riding "free" where it should be.

So to get the rear bottom down further I should adjust the rear wheel. Should I do this while it is in a pass or while sitting level on the ground?

Look at the plowed ground and tweek the plow accordingly to get the proper result you're after.

Make your adjustments as to what the plow is actually doing with the soil, wheather it be hitch height, tail wheel or a guage wheel. Think of it as "setting the soil" not so much as what the plow "looks like" while plowing.

So yes, if that tailwheel needs to come up a little, do it in the field. Stop, lift the plow to take the pressure off the wheel, adjust it, drop 'er back down and try it again.

The "skid" or adjustment "heel" at the rear bottom, which in turn, counteracts the suck of that bottom.

Jim: Plows that came from factory without tail wheel or gauge wheel, should have been equipped with a long landside on the back moldboard, and that long landside should have a shoe at the end. That is your depth gauge.

Thanks for the quick replies. I'll give this a try. The ground that turned over looks real good I'll just have to adjust the rear wheel. One other question when measuring a plow are you supposed to measure between the beams or straight across the beams, just curous cuz I have heard it being done both ways

Measure center to center of beams or easier for me is hang tapemeasure on a beam and measure to next beam edge(6 oneway,1/2 gozen the other way). Tx Jim

Also make sure the frame of the plow is parallel the ground side to side. If the ground is flat and level the frame should also be flat and level while in the ground plowing.
