Abstract

Embodiments of the disclosure are directed to a back-mounted power tool system. The power tool system includes a battery package that can be used on other power tool systems, a backpack apparatus, a power tool, and a connecting member. The backpack apparatus includes a backpack harness to mount the backpack apparatus onto a user's body and a first connector to removably couple the battery package to the backpack apparatus. The power tool includes a motor driven by a power supply from the battery package. The connecting member transfers a weight of the power tool and/or a force received from the power tool to the backpack apparatus by rotatably coupling the power tool to the backpack apparatus. The connecting member further enables the power tool to rotate about a first rotation axis or a second rotation axis, the first rotation axis being perpendicular to the second rotation axis.
