I cant really tell by the pictures but I dont know if I would call that big. It looks like a lot of work dragging the leaves out to the fround though. Going by leaf volume I have done larger cleanups than that. Try a 2 acre, heavily wooded park in a mobile home community. Everything was picked picked up by a mower, then ran through a giant vac truckloader. The job took 3 guys 4 hours. The f350 has a 12ft landscape dump body with 8ft sides on it. We filled up half the truck at this one account. We then moved on to 2 other large accounts, but both had less leaves.
Arent leaves fun!!!
