JD Plow on 4020 diesel?

Anyway I have been looking for a jd 4 - 16. There is a fellow posting a 4-14 that is tempting but that only gives a larger cut pass by 8 inches over the 3 16 oliver. But I would think the smaller rollover furrows would be easier to disc. So wondering what you guys think about which way to go is better. Also wondering what you like better...a trailer type plow or a semi mount. I wont be plowing alot but occasionaly and typically 3 acres to 100 acres.

Thanks,
John

Farmerboy, I am up in northern Minnesota so probably not too far away. I will be going through Duluth and accross the U.P. sometime this summer and doing a job on the michigan wisc border against Lake Michigan. Marinette. So will be going on 2. I will also be down in the cities once this summer also for a job.

Thanks for the tips on the plow models too. I think a 4 16 is what I will shoot for. I don't want to have the wheels up front light and don't want to wear weights...hmmm although I just did the math and 4 16's have 10 more inches than 3 18's.

I've used my father-in-laws 5-16 F145 behind a 4430 and it seems to clear trash OK. a 4-16 or 18 would be about perfect for your 4020. How far away are you from WI? I have a 4-16 345 sitting in the weeds. I've been saying for a couple years that it's going for scrap but haven't had the heart.

I think as long as you have the plow set right, it doesn't make a difference whether the plow is 14 16 or 18 inch bottoms when it comes to disking.

Disking without the differential locked, I found the 4020 would bounce side to side, broke off the muffler that way. It only bounces up and down with the differential locked which is a lot easier on the tractor and me.

Just touch a brake pedal to turn off the differential lock.
