Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.

Abstract: A fastener driver includes a pusher assembly slidably coupled to a magazine assembly. The pusher assembly includes a first portion and a second portion that are selectively movable relative to each other. The pusher assembly is adjustable between a first state in which the first portion and the second portion are configured to move together in unison toward the channel, and a second state in which the first portion moves relative to the second portion toward the channel. A dry-fire lockout assembly includes a blocking member coupled to the magazine assembly or the nosepiece assembly, and a lockout member selectively engageable with the blocking member for moving the blocking member from a first position and a second position. The pusher assembly is configured to transition from the first state to the second state after a predetermined number of fasteners remain in the magazine assembly.

Abstract: A powered fastener driver includes a housing, a nosepiece having a fastener driver channel from which fasteners are discharged into a workpiece, a driver blade, a workpiece contact element, and a pusher mechanism. The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position. A first spring is configured to bias the lockout lever toward the blocking position. The powered fastener driver also includes a last fastener holding member configured to maintain the lockout lever in the bypass position against the bias of the first spring, and a second spring configured to bias the last fastener holding member toward the fastener driver channel. Each of the first spring and the second spring is configured to impart a force on the fastener within the fastener driver channel.

Abstract: A powered fastener driver includes a housing, a nosepiece coupled to the housing and extending therefrom, a driver blade, a canister magazine coupled to the nosepiece, a pusher mechanism coupled to the nosepiece, and a cam. The pusher mechanism includes a body coupled to the nosepiece, a feeder arm pivotably coupled to the body, and a lever pivotably coupled to the nosepiece. The lever has a first end that is engageable with the body for imparting reciprocating translation to the body relative to the nosepiece in response to pivoting movement of the lever in opposite directions about the pivot axis. A cam is engaged with a second end of the lever for imparting pivoting movement to the lever. The feeder arm is engageable with individual fasteners in the nosepiece for sequentially pushing the fasteners into the driver channel in response to reciprocation of the body relative to the nosepiece.

The powered fastener driver also includes a dry-fire lockout mechanism having a lockout lever movable between a bypass position and a blocking position and a last fastener holding member configured to engage a first side of a fastener within the fastener driver channel. The lockout lever is configured to engage an opposite, second side of the fastener within the fastener driver channel. The last fastener holding member biases the fastener within the fastener driver channel toward an inner surface of the fastener driver channel to inhibit the fastener from falling out of the fastener driver channel.

Abstract: A cultivator tool includes a power head having a handle and a user interface. A motor is positioned within the power head and is configured to rotate a drive shaft about a drive axis. The cultivator further includes an attachment stem removably coupled to the power head at a first end and removably supporting a tool attachment unit at an opposite second end. A cover is receivable on the attachment stem between the tool attachment unit and the power head to cover a cutter rotatably supported on the tool attachment unit. The cover includes an aperture configured to receive a projection extending from the stem to limit rotation and sliding of the cover relative the tool attachment unit.
