Re: 9770STS
Everybody says the 9770 will do the same as the 9860 will but both our 9770's we've ran this year will not hold a candle to our 9860. They do fine till the unloading auger is on in higher yielding corn (200+) then it seems like the horsepower is cut way back and the 9860 doesn't slow down any. The only thing we've ran them side by side in is corn so I hope this helps.
