Sweeping: Denotes speed of moving leaves.

Loosening: The speed of removing embedded leaf particles from a lawn.

Handling and ease of use: Includes ease of maneuvering, using controls, and changing modes.


Weight (lbs.) Weight To the nearest half-pound in blower mode.
cc/amp cc/amp Engine cubic centimeters (cc) and motor electrical amperage (amps) are from the manufacturer.
Multiple speeds Multiple speeds On an electric blower or a variable throttle on a gas-powered blower, these let you increase power for sweeping on hard surfaces or open ground and decrease it around fragile garden beds.
Vacuum capability Vacuum capability Comes with the necessary attachments including a collection bag to convert to vacuuming mode for sucking up leaves and debris.
Translucent fuel tank Translucent fuel tank A clear tank lets you see at a glance when fuel is running low.
Spring assisted starting Spring assisted starting To makes starting easier, a pull-cord assembly with this feature has a built-in spring that winds up as the starting rope is pulled, to reduce the force necessary to start the engine.
Four-cycle engine Four-cycle engine Uses straight gasoline and doesn't require an oil/gasoline mixture, as do the more common two-cycle engines used on most trimmers.
