Dealing on a used W150 (35ft head). Doesn't have double draper drive. I think I read that when Macdon improved their roller and increased their draper tension, double draper drive was less of a necessity. Opinions welcome!!
We just traded off a 2952 w/ 972 header (30') that had single draper drive. No trouble. The MacDon we had before that (can't remember which model), we had to field install the double drive because heavy canola swaths would stall the drapers.
Current W150/M150.... no idea, but I would think you'd be OK.
