4000/350 is what we used in our D1000 for years. Due to the 350 strength twine becoming less available we tried 4000/440 and it has worked well. I have spoken extensively with another D1000 owner who was also a net and twine dealer and he said his D1000 did not work well with the 440 twine. His baler was an earlier serial number unit with twine discs of all the same thickness. The balers after the major SN break have a twine disc with a much thicker lower disc and that is what ours is. We concluded that the later twine disc may be why the 440 worked in our baler well but not so well in his.
Just saw ur vid. Are those bales 22 inch high, how heavy, what other way to know moisture limit without stopping and testing when ur in a rush. I'm sorry i have tinnitus, i can still hear but i have done enough tractors these days i don't want to listen. I make 3x3 on my second cut alfalfa 440- 450 twine can't get 350 they break on straw
