I agree with you on that ron.. One of the first things i mentioned when i demoed the s630 was it felt like i was running a s220 power wise there really neck and neck but i did feel i was able to push into a pile better with the 630.Check out the S200 vs S630 bucket fill and dump, what a joke, real operators wouldn't keep the wheels spinning and level the bucket as they dump.
the 630 is stock quite a bit heavier. Maybe that extra weight helps it push into the pile?
If I the GPM was 37 and not 30, I'd be interested. The large frame machines coming out will have plenty of power BUT they are going to be heavy! This is going to be a year where I will have to break down and get my CDL.
