A buddy of mine has a leaf plow and although they are great at moving piles of leaves they also compact them to the point where it is difficult to vac them up and they have to be broken up with a steel rake first. The problem with a wheel blower is you can only blow from the back of the pile and after a while you get an immovable wall. You can break through it, push some of the leaves ahead and then funnel the rest of the leaves through the slot, but that takes time. With a large backpack blower you can blow the front of the pile forward and then bring the rear of the pile up behind it. I find that my wheel blower actually wears me out more than my 580 does...I've never been huffing and puffing and sweating using a backpack blower the way I do using a wheel blower on turf. I reserve my wheel blower for pushing leaves through slots such as gaps in hedge rows or a fence gate or pitching leaves into the woods...often leaving it stationary and feeding it with my backpack blower. When it comes down to it I find that the control and versatility of a large backpack blower wins over the power of a wheel blower in most situations. As far as a leaf vac goes, I don't find much use for that either. To me it's like moving the mountain to the man rather than taking the man to the mountain....you have to get all the leaves to your rig. I prefer to pick up with my mower and rear bagger. I guess a lot has to do with the size or your crew, the properties you service and your preferences. I'm fortunate that I only have to haul leaves on a handful of my accounts. On most of the propeties I service the leaves can either be blown into the woods in bulk, blown to the edge of the woods and shredded with the mower or picked up with the mower and then dumped to the woods or a compost pile.
