Yes, that is possible.I have never heard of a D series 40' having only one knife drive. Are you sure of that?
Well I'll be....................file that away in the memory banksPhantom970 Yes the one I am looking at is single drive
HiCombineguy What happens to the Vario in damp straw? I thought the Vario would be a lot better for that
X2. Have both headers for a 590. Vario 30' only used for canola so do not have experience in cereals. I have considered only keeping one header and wonder which to keep. The Auto Contour works well on the Vario but we have never been able to get the Float Optimizer on the D50 to work.HI
Have ran both this year, 30ft Vario and 35ft Macdon. If your handing damp straw then the macdon wins all the time, as will just keep on feeding, no matter what the conditions are like
