A power tool (10) includes a power tool housing (18) at least partially-encompassing an internal combustion engine (14) and a harness (12) on which the power tool housing is mounted. The harness has a pair of shoulder straps (16), a waist strap (24), and a panel (44) connecting the shoulder' straps and waist strap. The power tool housing is mounted on a frame (30) having at least one arcuate tool-supporting member with an upper end proximate the shoulder straps and a lower end proximate the waist strap. The tool-supporting member is shaped along its vertical length such that a middle portion of the member arcs away from the panel such that there is an air-circulation space (S) between the power tool housing and the panel. In one embodiment, the power tool is a blower and the housing has an air intake port (46) facing the air-circulation space.
