While rotary mowers, sickle bar mowers, or hand-held weed cutters are small enough to work around obstacles, none will do the work (with the ease) of the Outback Brushcutter.
Not only do you have to carry hand-held brushcutters, they only cut debris once, meaning you also have to clean up after them.
Rotary mowers can mulch debris, but because they have low, enclosed housings, will choke and stall on anything more demanding than a manicured lawn.
Sickle bar mowers are made for heavy weeds, however, they only cut debris once, leaving ground clutter to clean up. Additionally, the side-to-side motion of the sickle bar creates a violent, tiresome vibration on the operator.
Only the Outback Brushcutter is small enough to work around obstacles, is self-propelled and specifically designed to cut, chop and reduce heavy vegetation.
