600 backpack on the right
and a 530 on the left.
point the 530 at the leaf pile and kind of scoop the leaves into the 530 airstream with the 600
Whole lot of work in a very short time.
Had a 530. When I saw the 600, had to have it. I'm lefty and the 600 is right handed. It felt awkward with my left arm just hanging so I picked up the olde 530 with my left. WOW. The combination is so much better than twice as good. Roughly twice the power and especially so much more control of where they go. Much faster.
