I got forced into buying a 30'Vario about 5 years ago when the canola froze about a week before swathing stage. In 3-4 days it was brown, stiff, dry and fluffy and would not flow through a swather or a draper header ( HB and MD without augers). In the 6 weeks of letting the canola mature and dry while standing, I bought the Vario and installed Auto Contour on my 590R. It worked so well that I have not swathed canola since. Those tall , lodged and twisted canola crops that we try to grow are just no problem. It still takes a lot of power to put that rank green stuff through the machine, but it feeds very well. Almost no slugging and plugging of any combine components. Less straw breakup and overloading of the sieves. In the first year of frozen canola before maturity, my green count at sale was substantially lower than swathed seed. Mine made #1 all but 2 loads of the worst green low spots that is easy to see and cut out separate.

Mine made #1 allbut 2 loads of ing on the wide pan behind the knife is an issue after dark when the dew comes on, but only when coming into the crop to start a new pass. After the flow of material is going it feeds fine. The auto contour works well enough for cutting canola but as low as we ever cut in lodged crop would be 4". The auto functions work very quick and well for header ht, reel ht, FA, reel speed all with one touch of the button. Very happy with the vario in canola.
