two of the 480's will do almost as much as the 3 of the 9750's. with 12r30 head on a 9750 most of my customers in west neb can run about 4 - 4.5 mph or about 3000 bu_hr without excessive loss over the sieve. with the 12r30 on the 480 your only real limitation is how much head loss you think is acceptable. had a customer that averaged over 4000 bu_hr over a couple of days last year. creates a whole new logistics nightmare for the unprepared. if you do any soybeans the difference is even larger due to the hp differences. the 9750 is a good machine, but it is not in the same class as the 480. it just has too small of sieve area for the hp and the threshing capacity. this has been the most common complaint of the owners that i have talked to. i have a copy of an idependent test conducted in mn. last fall with a 480, 470, 9750 all with 12r30 and a 2388 with a 8r30. the corn avg. 161 bu_ac with a test weight of 56lbs_bu. all the machines were ran and set by factory personnel. the 480 reached a 1% loss at 4500 bu_hr. the 470 reached 1% loss at 3300 bu_hr. the 2388 reached 1.25% loss at 2500 bu_hr. the 9750 reached 2.5% loss at 3000 bu_hr. read the numbers however you want to, i dont hold much stock in these kind of comparisons. it is too easy to tweak the results to make them fit your expectations. i have, however, seen comparable results in actual field conditions with farmer owned and set machines.
