Hmm yes and no!! After you hyperize your machine and you are running 50% faster than before when in the same conditions as you have been now, you might find it be nice to have more GRUNT! Its been so long since we had a stock machine, that I'm not sure how much better we are now that were hyperizedIJ I do know that when we brought our 94 R62 and used it the first year, I thought we had really stuffed up! I would be lucky I think to be running 5 to 6 kms_hr in our current crop that were harvesting now, (2 ton_hectare wheat) were currently doing 11.1 ks_hr with the same machine at 260 rated HP,9.1 meter flex 500 front and approximately a tad over 5 ltr fuel_hectare, neighbor's up the road have same mode R 62 header but with 9.1 meter draper front and is running about the same speed with almost stock setup! so a draper must add about the same % as hyping your machineIJIJ Tbran, Dan how much does a draper add to performanceIJ could do with a 15 meter draper in the wheat about now! and slow down some Rolf
