With my 9770 in 30' of crop, I'll average between 10 and 15 acres per hour. Again, it is totally dependent on conditions such as fields, good windrowing, lodged grain etc.
9600 with 30' swaths, wheat (50 bu), oats(120 bu), barley(70 bu), canola(40 bu), over the season average about 10 acres per separator hour. Do the math on bu/hr.
Would like to know how many acres per hour guys are getting on there machines. More curious on the bigger machines, like the 9870's, and 9860's, but would like to see all to compare. Thanks.
Conditions and different crops are a factor, that's why i've asked to average it out over the year.I'm not asking what the most you have ever combined per acre.
9870...5 mph avg...21 acres/hr (35' straight cut, 36' swaths)
For every mph faster or slower decrease the acres/hr by 4
Average year, 5 mph is a good average.
To make you're formula more simple mfinmo you can take (width(FT)/8.25)XMPH. For a header you will cut 3.63 acres every mile, knowing that you can quickly calculate your theoritical acres/hr by multiplying speed.
