I got a commercial property yesterday that has a large parking lot that I have to blow off every week. I used my PB260L to do it last night but quickly realized that my blower is a wimp. I went through 2 tanks of gas on that thing before I was finished. Way to long to complete the job. I am picking up a new PB650 this evening. Now for my questions: 1) Will the PB 650 be enough? 2) Do I need to invest in a push blower ie. Little Wonder? 3) Would a Billy Goat walk behind vacume do better? 4) Is there a better way that I havn't thought of? I really need some insight on this. I know there has to be a better way. My Ferris dealer said there is an attachment that I can install on the front of my 3000 to make it push the Little Wonder or any other wb blower. That sounded neet to me. Is anyone using something similar. I also saw the new sweeper unit for a Walker. It is sharp and does a good job but I believe they said the price was $2800. I'd have to do alot of parking lots to justify that. Especially since I would have to by the Walker also.
