I have a new 35' Macdon FD 75. We've only cut about 250 acres milo and about 200 acres of beans with it. Really like the header and the job it's doing, but the cutterbar has locked up 4 times when cutting beans. It only happens when you're cutting directly across the rows and the whole 35' hits the row at the same time. When we stop and get the stalks out of the cutterbar, it always starts right back like there is no problem. The drive belt is plenty tight and you can never smell the belt slipping. Seems to me like the hydraulic drive is stopping, not slipping the belt. I ran it the first day so I could get the hang of it and learn a little about it before I turned it over to the regular operator. It locked up with me on the second pass across the end. I tilted the cutterbar back and it hasn't done it again until it did it 3 times this afternoon. Wondering if there is a problem, or just running with it tilted too far forward? I did have operator tilt it back a little after it did it the first time today, but still happened twice more. Doesn't seem to be getting in the dirt at all, but it is cutting pretty close.
TIA
