the clean grain on these combines is not near enough for a 12 row. we cant elivate it fast enough. im afraid a 12 row would be a really bad deal for a 97. we also run a 6 row (we have an 8, but no planter). our 98 runs like a champ in 140 bushel corn at 6-7 mph. i guess what im trying to say is, you would cover no more acres by having a 12 row (besides cornering) so i am at a loss for why it would be economical to buy one. lemme know how it goes though, please!
I can't imagine why you couldn't run a 12 row head since they have the optional parts to beef up the header drive specifically for a 12 row. Obviously you couldn't go the same speed as with an 8 row but you are covering 1 1/2 times as much ground in each pass so if you dropped you speed 1 1/2 times you would cover the same ground. Basically from say 6 mph down to 4 mph. So what is wrong with that? Pretty sure a TR97 will go close to 4 mph with a 12 row unless in 200+ bpa wet corn. There is a possibility I am wrong though. There has to be several on here who have run a 12 row on a TR97 or the like.
