JD 4020 Plows

[DONMYEIL]

If the 3-point hitch isnt adjusted correctly that plow will pull like it has another bottom on it. Proper weighting is a must because if the front end is light the 3-point cant work. You need the base weights plus a slab weight for the tractor and one slab for each bottom to start.Then you weight the rear end for proper slipage.We had customers that pulled anywhere from 3/16 to 6/16 or 4/18 or 4/20's. depth any where fron 5-6 inches to 10 inches.Most common was 5/16 plows.

I've always ran F145 5x14" JD plows on our 4020s just fine. Sometimes it can pull like a bugger but 95% of the time I run just fine in 3rd or 4th gear. We have some clay areas. Our 4620 pulled the 1450 6x16s about the same. The 4620 was set to 150hp and the 4020s are factory set hp. I normally run the plow 10 to 12" deep, I did get 3 to 14 with the 4620 one year on some light river bottom soil and never knew I was running that deep until dad came out and looked, it was running nicely in 5th gear with that big plow and never lugged down. On the other hand I've had some dirt that dried up into concrete and 3rd was more than the tractor had.
