Improved cooling systems for handheld devices are disclosed. In some aspects, the cooling system may utilize air inlets disposed behind a guard to prevent debris or liquids from entering the handheld device and potentially causing damage to internal components of the handheld device. In aspects, vents may be disposed on the guard to divert cooling air into a housing of the handheld device to cool internal components, such as the motor or a printed circuit board (PCB). In some aspects, a motor mount may be provided that includes ribs defining air channels to divert or direct cooling air to components to be cooled. The air channels provided by the motor mount may enable the cooling air to reach portions of the internal components that may be distant from the air inlets of the housing. Transfer housings and gear guides may also be provided to improve stabilization and enhance cooling.

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.

A gardening apparatus having, in one form, a shaft for being operatively connected to and rotated by a motor. The shaft including at least one vane extending therefrom and having a plurality of tines extending therefrom. The vane further having a raised wall extending therefrom. In another form, the apparatus includes a handpiece having a power source, motor, and a drive system operatively connected between the motor and the shaft to perform a variety of tasks such as tilling, hole digging, and/or weed removal.

A scraper glove is provided and includes a glove body including one or more finger sleeves; and one or more scraper elements. Each of the scraper elements includes a receptacle portion positioned within a respective one of the finger sleeves to accept one or more fingers of a user, and a scraping portion with one or more scraping edges extending from a tip of a corresponding finger sleeve and integrally connected to the corresponding receptacle portion, wherein the scraping portion is configured to scrape a plant-based medium.

Systems and methods for using interchangeable tool attachments in multi-use tools. In one embodiment, a multi-use tool includes a motor, a shaft and a shaft adapter at the end of the shaft. The motor has user controls (e.g., on/off switch or throttle) that control the motor to drive the shaft and cause it to rotate. The shaft may include a rigid tubular outer member with a flexible inner shaft. The shaft adapter is coupled to the end of the rotating portion of the shaft. The shaft adapter has a mounting flange that rotates with the adapter at the end of the shaft. An interchangeable tool attachment is secured to the mounting flange, and rotation of the shaft adapter and mounting flange causes the tool attachment to rotate as well. Many different tool attachments can be interchangeably secured to the mounting flange to provide corresponding, different functions to the tool.

An adjustable guided rake apparatus and method, which enable an adjustable guided rake user to configure an adjustable rake guide to a specified height in relation to a secondary surface, which will then define the height of the grading edge of the grading rake head in relation to a primary surface. The adjustable guided rake user is able to move the grading rake head along a primary surface, in order to shift material along the surface, while the adjustable rake guide runs along the secondary surface, guiding the grading rake head.

A handheld lawn maintenance tool having a power head to which an adapter is attachable to allow both battery-powered and gasoline-powered working attachments to be attached thereto. The power head includes a power source, integrated first and second handles, a power generator, and a first attachment mechanism to which the adapter and/or working attachments are attachable.

A portable device for collecting particles and microorganisms is provided. The device includes a cyclone enclosure for centrifuging air, external air inlet for admitting air into the enclosure, and air outlet connected by a coupling to an air inlet filter of an individual motorized respiratory protection appliance.
