I have chopped 100"s of acers with a 35 and a 4020 and in my experience it is lack of horsepower that slows you down not chopper capacity.I think you need to go over your cornhead make sure the cutoff knives are adjusted and sharp(like to set mine up to cut paper)make sure gathering belts are good and in time.You need to make sure both feed roll springs are hooked and all feed rolls are working.With a two row you probaly want to use the small side of the large feedroll drive sprocket.(If the harvester had a one row head it will more than likely have the little sprocket which is to fine a cut,we run the large side of big sprocket)Sharpen your knives sharp and set the shear bar as close as possible.If your shearbar is wore down and rounded it will pull hard.Do not forget that there is a bolt in the middle of the shear bar that must be loosened before adjusting it.We did custom work for years with a 4020 and a 35 with no problems.Now if you want to go newer look at a 3940 or 50 to pull with 4020 if you want to use 4440 a 3960-3970 might be better.The Deere harvester pulls much easier than NH or Gehl and has less parts.The NH 824 cornhead is better than a Deere and there are adapters to put them on a Deere.A friend and his brother each have one and would not go back to a Deere head.We still have our 35 but now use a 3940 behind our 4520 mainly because we like the small knives and knife sharpener and quicker adjust shear bar especially in hay.

Today's Featured Article - The Nuts and Bolts of Fasteners - Part 2 - by Curtis Von Fange. In our previous article we discussed capscrews, bolts, and nuts along with their relative hardness and thread sizes. In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and ... [Read Article]
