Gotta get into igloo country to see them in NA. Piles of them up here in Canada. They just FlY through the windrowed crops that we have. little straight cutting up here. I'd say the TX 66 are a couple acre_hr faster than the maximizers. The TX 68 are quite larger capacitaed than the maximizers. Biggest cleaning area of all combines. Does a terrific job on the high yielding light crops (barley, oats). Doesn't throw much over. Beautiful machines to run, but require more maintenance than the Maximizers. The prototype to the TX series was setup with an automatic greasing system. But, they scrapped that idea believing the farmers wouldn't give the machine routine checkups and maintenance. I posted this before but it didn't seen to come on the General Forum.
