Green with envy here. I don't have any fields like that nor have I ever seen one. Knee jerk reaction was to call BS on this but then I put a pencil to your numbers and low and behold it is doable. Just shocking what having a big cutter in a smooth field that is square does for production. My numbers show that you averaged between 10 and 11 mph if cutting 100% of the time, take out for turns and I am sure you are running GPS and not having to make slow turns so not a lot of time wasted. So a little 18 mph a little 6 mph and a lot of 11 or 12 mph and you get it done. I usually average around 7 acres an hour with a 10 ft cutter. Rough fields and odd shapes keep my production down but another factor is my tractors in C range 3 and 4 are the most used gears giving me 6 to 8 mph available. Go to D range and 1 is 10 mph. I can run D1 in some places and even bale in it sometimes the problem is when in D1 there is no down shifting for rough places and turning on the ends. Of course the only places we get to bale hay around here is fields that are either to rough or to small to plant corn on. On a side note I remember when Dixie Chopper mowers came out and they advertised as the worlds fastest mower. They ran an add stating their top speed, the width of cut and the acres per hour they could cut. Only issue was if you did the math even if they cut a path right down the middle of the road and never slowed down they could only cut about 1/2 what they claimed.
Myself I would rather have a rig that was 36' or even 60' wide and then travel at 4 mph and I would even at 36' would do about 12 ac/hr and at 60 would also likely be able to get into the 20 ac/hr.
That while traveling so that I could likely do almost ever field at that speed.
Never built the rig though - - - most people seem to prefer the go fast to the alternative.
Interesting was to hear (haven't been able to prove it though) that alfalfa would regrow up to 4 days faster with a sickle cut machine (I think that was a sharp sickle rather than a worn out beat up pos) than with the flail cutter type.
That - - - to me would pay for the difference in speed even more than anything else. My idea is maximum high quality tons per year. (notice the qualifier!)
