Ok, I now stand corrected, found the issue. Just spent 2 1/2 hours going up and down steep hills, in and out of trees and it performed flawlessly.
The forward drive pedal is really stiff, I thought I had it all the way down, but did not. I really had to stand on it to get it all the way engaged. It seemed to get easier as the day went on, at first I thought there would be no way that I could hold it like that for 2+ hours, but in the end it was fine.
In fact, the reason I wanted the 2415 over the 2615 was the small footprint and today that really paid off.
In the time I was out there about 2 acres got mowed, based on the steepness of the hill and the trees you would not just drive one way and then go the other , it they type of area you have to finesse.
Thanks for the thoughts.
Matt if you want to get some more time on the 2615 bring it on over, I have another 3 acres to do.
