any capacity differences 2012-2014 S series to 2015-16?
Deere ads claim the hydraulic concave gives 10% more capacity at same loss and up to 20% more capacity when tough. New dyna flow 2 cleaning fan adds 10% more capacity at same loss. So real life numbers in the field, is a 2015-2016 S680 or S690 doing 20-30% more capacity at low losses than the 2012-2014 years?
Would like to trade off my 9870, but would like something that consistently does 30-50% more capacity. Harvest peas, barley, spring wheat and canola. Usually dry conditions at harvest, but lots of straw. Irrigation in Alberta.
