Abstract: A trimmer head includes a housing rotatable about a rotational axis. The housing includes a main body defining a cavity, and a cap removably coupled to the main body. The trimmer head additionally includes a spool supported in the cavity and operable to support line to be dispensed, a retainer positioned between the housing and the spool, and a first ring protruding from a distal end of the housing.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a driven or bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. The drive unit includes an output shaft. The powered fastener driver also includes a rotary lifter engageable with the driver blade. The lifter is configured to receive torque from the drive unit in a first rotational direction for returning the driver blade from the BDC position toward the TDC position. The powered fastener driver further includes a kickout arrangement located between the lifter and the output shaft. The kickout arrangement is configured to permit limited rotation of the lifter relative to the output shaft between a first position and a second position.

Abstract: A reciprocating saw including a motor defining a motor axis, the motor including a front end and a back end, the front end including a front face defining a first vertical plane, and the back end including a rear face defining a second vertical plane parallel to the first vertical plane. The reciprocating saw also includes a dual-eccentric scotch yoke mechanism coupled to the motor. The scotch yoke mechanism includes a spindle driven to reciprocate relative to the motor along a spindle axis parallel to the motor axis, the spindle including a rear end nearest to the motor. The scotch yoke mechanism also includes a counterweight driven to reciprocate relative to the motor. The spindle is arranged above the motor. As the spindle reciprocates forward and backward, the rear end extends into a space defined between the first and second vertical planes.
