Not sure what brand or size you are looking for, but will try to help. I'm going to be very biased toward the MacDon, they've been building drapers much, much longer than the other companies and it's what I run. You will be able to tell the difference between the flex and the rigid when you look at it, also any flex model begins with the letters FD. Make sure you pick up the head and check the cutterbar, center and side draper belts, center drum, chain that turns the center drum, reel bushings, any bearings you can see on your draper rollers, oil leaks on hydraulic motors. I've run approximately 12,000 acres through each of the 2 I currently have and only replaced one hydraulic motor that drives the left side draper. they are very dependable and do an excellent job of cutting and feeding in all crops.
