4200 Rollover Adjustment

I posted pictures of my JD 4200 rollover (3x18" NU bottoms) and 4320 tractor several days ago. One challenge I faced here in western Wisconsin's hills and clay soil is getting the furrow to turn over and not plop down when plowing up hill. The issue is worse in the clay and worse in sod. Grades of about 7-8% start to cause issues and it gets worse from there. And, the plow drifts more down hill so the front bottom overcuts, this seems to make it all worse.

It sounds like some of you have 4200 plows and might give me some advice. I have the R/L stops set at 2.5" as the manual recommends. I played with this setting a thread or two but did not get improvement. I put brand new landsides on the rear bottom, helped a little. The other landsides are good-fair. I played with the third link adjustment a little but I don't recall much difference regarding this issue. In hindsight I might of adjusted this more to see if it helped the tracking. I was running in 3rd gear, tried 4th and that helped. (these hills have some rocks, even bedrock outcroppings, so I was not eager to go real fast as I may damage something before the bottom trips.)

I have cover boards on all bottoms and a coulter on the 3rd bottom only. I do not have those extensions off the end of the moldboard.

I have been told the 18" bottoms have a little more issue turning the furrow. That makes sense because it is so large.

Anyway, I was hoping someone out there might have plowed with the 4200 in these conditions and might have some suggestions. Or, is this just the way it is with the 18" NU bottom.

I have several F145 16" semi-mount plows with the HS bottom, they plow so much more smoothly. They can have the same problem but at steeper slopes and I have the advantage of adjusting the lift links independently.



I said a lot here, in summery:

1. How can I improve tracking on side hills?
2. How can I improve soil rollover on side hills?

Any comments.

You really need moldboard ext. on the rear bottom when throwing up hill. This is especially important if you are plowing sod.More speed helps,if you can. 18" bottoms are harder to roll.Set it back to 16",go 4x16 if you have the rear bottom.Set it level,and it should 'track' fine,provideing the landsides are in good shape.It may help to shim out the landside a bit to correct the 'tracking' issue.

Thanks DeltaRed. I have never used the extensions so don't know the effectiveness. I will look for a set. Paul

If you really want to plow sod and turn it over good you need to get an Oliver plow. No I am not trying to be smart here. We have a Deere plow and an Oliver plow. There is a world of difference in how they will turn it over. As for the roll over the bottoms would be the same.

Thanks. I don't doubt you. I have heard a lot of good things about the Oliver plows. For now I plan to try a moldboard extension. Thanks. Paul

I have to agree with caterpillar guy, we have a 4200 set a 3-18 that we use and I will say it does not do as good a job flipping soil over as our Oliver 3-16 and 4-16's. I find you have to move at a pretty good clip to flip the soil over with the Deere plow.

Did Oliver make a late model rollover plow that there might still be parts available for? Paul
