I have about 2000-2500 sq ft yard (front and back) and need help assessing which leaf blower to purchase. I have a large maple tree in the backyard and two large cedars in the front. Needles year-round and large wet leaves are in my future, being located in western Oregon. I have a large patio along the back of the house, near the maple, so it's constantly getting covered with debris from the tree. I currently use my leaf blower every few days to keep the debris and needles off the driveway, sidewalk, and back patio. I have an electric blower now that blows 380 cfm. I used to have a Husqvarna 150BT backpack blower but would like something with more power. I recently purchased a Husqvarna 570BTS which blows at 768 cfm. I paid $499 for it and am wondering if it's overkill for my needs...but it certainly got the job done quick. Thinking I may exchange it for a 550BT but that drops me down to 494 cfm, but it costs $360 which would be a nice savings. Thanks for your feedback!
