I have a large leaf job at an apartment community. I am blowing the leaves with my echo backpack blowers. The piles have become large and I have ended up making large piles throughout the complex. I need to get the leaves to the curbline (approx. 50 yds.). My piles are 3 to 4 fee deep and30 feet across. I anticipate on renting a bobcat and moving the leaves to the curbline. any other ideas or an easier way to do the job?
