Plow adjustment

[toplineredangus]

Hey guys I have a set of 3 point hitch 3-16 john deeres and the problem I am having is after I get them set up to plow. They do a great job they plow at about 8 inches but the problem is I can't get them to come up high enough when I raise them.the front share is about 1 and a half feet all the way up and frome there the second share is about a foot or so off the ground and the back share is only about 2to3inches off of the ground. Anyone have any ideas cause if I bring the top link in toward the tractor to correct the problem then that throws the plow out of wack and then the front is pointed way down while trying to plow and the back will be out of the ground almost. I will try to post a pic maybe this weekend if it is dry enough to plow.

You should have more than one hole on the tractor end if the toplink clevis. Move the toplink down one or two holes. Moving it down changes the geometry so that the toplink and liftlinks are more parallel.

If tractor is equipped with draft control changing top link attaching hole will also alter draft control sensitivity on tractor. Do you know what model JD plow you have? I sure hope you can post some close up photos.

The perfect solution is to get a hydraulic top link and retract it when lifting the plow out of the ground. But those are expensive and unless you are plowing commercially it may not be cost effective.

Oh, and a tilt hydraulic cylinder really makes the adjustment easy for the "first pass/succeeding passes" adjustments. Nothing like fine tuning the plow's performance from the tractor seat on the fly.

I agree that plows tend to dive, or rotate, into the ground and have to be set a bit elevated in front to even things out when the plow is working. But your set-up is on the extreme end of the observation.

When plowing does the front of the tractor lift or lighten a bit (you can tell by the steering)? Front end weights may help that issue and will allow the plow to be set more level. If you have a FEL try filling it with dirt or sand to see if that makes a difference on how the plow runs.

Agreed. If set up right, the front share should be the lowest, not the highest when raised. Shorten the toplink. Plow frame should run pretty close to parallel with the ground when fully engaged.

Do you have a picture of your setup?

What he said.. something is definitely out of whack here.. There's no way the rear plow should be the lowest when raised. I have the opposite problem, my front share is the lowest, almost touching the ground. If it's set up like mine, the top link should be in the lowest hole on the tractor. From what you've described, it sounds like the front of the plow is lifting more than the rear does, which I can't quite picture happening.

Now that I've read this, I might try mine in the second hole from the bottom, see if I can get the darn thing to lift more level. Thanks, I think..
