To answer the pricing discrepancy, the $350,000 are obviously Canadian dollars. The amount, and the mention of barley, canola, and wheat, gave it away. What height are you cutting the strawIJ Excessive straw will decrease capacity substantially. As far as settings, I can only impart what seems to work well on these machines here in ND. Concave 0.2, rotor speed max. (wish these machines had another 200 rotor rpm to play with),Fan at 1350 rpm, No blanks installed (if hard thresh may run one but wouldn't try all 3). We prefer to run all wires installed and keep the rotor blanks out. If straw gets tough or weed pressure is high, all rotor knives installed. Good luck.
