Neighbors with a 9610 aren't even out of the shed when I start to combine with my lowly old N6 and go to bed much sooner. Both are running 20' flex and my PROBlEM is the sickle speed. I can put more in than the sickle can cut without pushing it over. Mine is P1 Hyperized, but the neighbor has all accessories on the 9610 too. With a P3 and 50 more HP than my N6 there should not be a contest. Neighbor with an R62(Stock) does not do any better than my N6 Hyperized. Conclusion, if I can easily beat a 9610 dressed out with my Hyperized(dressed out)N6 than an R62(stock) should easily win too. And don't even talk about Corn and a Rotary over a conventional. Deere would NOT have gone that way after 20+ years of bad mouthing Rotary designs if it wasn't better. Other neighbor with an STS can't keep his in the field, his 2388 does about 75% of the work, this is a first year STS and has had more updates and repairs than imaginable. Hopefully Deere has gotten most of the bugs out of the STS.
