Our lot is smallish (33' x 155') with lots of trees and shrubs. Lots of snow in the winter, and cannot park on the street in winter so parking is off the back lane at rear of our lot.
I'm sort of old-school, and have accumulated many tools one at a time over the years. For yard work almost all power tools are corded electric. (Exception is my snowblower, a gas Ariens 24" wide unit because sometimes I need to clear the width of the back lane over 200 ft long to the end street, and an extension cord and small snow thrower would never do that!) My mower, weed trimmer and hedge trimmer all are corded electric. In the Pruning Dept. I have two common garden pruning shears, two loppers (the better one has telescoping handles for extra leverage on heavy branches), a reciprocating saw with a long woodcutting blade, a telescopic pruning pole with manual rope-and-levered shearing jaw on top and a removable curved saw blade that is remarkably sharp and does the job well, and an electric chain saw. That latter is suitable for something 6" (maybe 8 to 9"), but it is NOT what any pro woddcutter would use. I'm not a pro! So with all those and a couple ladders I can handle most pruning jobs in the yard.
This summer we had an unusual downburst wind that snapped off a large Black Spruce tree (maybe 20" at base, over 50' tall) in the neighbour's yard and two large branches of cedars in our yard. I trimmed many of the fallen branches, but the main tree next door and our cedar pieces were hung up on other trees and too large (and hazardous!) for an amateur. Both of us hired pro tree contractors who really knew how to handle those for us, chipping much of the material into a truck for disposal.
