I’ve got two yards to blow out, mature oaks (75 years) and maples bordering 2 sides, 2 more 75 year old oaks on the property and ridiculous amounts of leaves to remove every year. I went with an EGO Power+ LB6504 650 CFM Variable-Speed 56-Volt Lithium-ion Cordless Leaf Blower 5.0Ah Battery and bought a second 5.0Ah backup battery.I do still have a gas backpack blower.
This thing does a great job moving heavy oak leaves and branch ends. The variable speed thing is great, and it has a “turbo boost” thumb button which enables me to move even the most stubborn branch or advance 3 foot tall piles of leaves. Love it.
