I have been around a few doing corn, soybeans, and small grains. A real fine machine. I think the C65 is a ways off from what I hear, but the C62 will remain in production until C65 is ready. Think Gleaner just concentrated on the rotary first, as it is their bread and butter. The C62 can be 'hyperized' (if I may borrow a phrase) just like the rotary can, and some guys I have talked to in Canada have tweaked these machines with great success. Some things I would consider, especially for corn_beans: There is a set of more aggressive straw walker risers available through AGCO dealers that will increase walker capacity especially in small grains but also help in corn. I think the Canadians told me that the '02 C62s have a new concave that has wider spaced wires (a hi-wire version) for big increases in capacity. We found this was the C62s biggest limiting factor in corn was the old concave's wire spacing. It is originally about 1" so we cut out every other wire in both sections of the concave. What was happening was that the original concave was not allowing enough grain to escape and would overload the walkers. The wider spacing from the new concave or by cutting out every other wire gave us a very noticeable increase in capacity. With just the concave mod and the walker risers, we picked one field of corn yielding over 200 bu_acre with a C62 and 8 row 30 cornhead at 4.5 mph with under 1 bu_acre loss. Pushing the machine to 5 mph in that condition, we were up against the engine's horsepower limit and started losing more than 1 bu_acre. Pretty impressive for a conventional! The Canadians are also experimenting with speeding up the 2 beaters behind the cylinder and this has given them even more capacity in small grains they tell me. Don't know that it would help us much in corn_beans. Hope that helps. Good luck with the C62. I like that machine a great deal.
