A mobile vehicle, a ground treating equipment and an orientation adjusting method thereof are provided. The ground treating equipment includes a frame, a ground treating unit, a connecting rod set, a connecting rod driving unit, a rotation driving unit, two pressure sensors and a controller. The ground treating unit is mounted at the frame. Two ends of the connecting rod set are connected to the frame and the mobile vehicle. The connecting rod driving unit is mounted at the connecting rod set for adjusting the orientation of the connecting rod set. The rotation driving unit is mounted between the frame and the connecting rod set for driving the frame to rotate relative to the connecting rod set. The pressure sensors are mounted at the frame for sensing two pressure values between the frame and ground, or the pressure sensors are mounted at the rotation driving unit for sensing two pressure values while the frame is driven to rotate clockwise and counter-clockwise. The controller is configured to control the connecting rod driving unit and the rotation driving unit for changing the two pressure values.

A blower including a base having a housing, a handle extending from the housing, a power source positioned within the housing, the blower including: a drive shaft extending forwardly from the power source, wherein the drive shaft is rotatable by the power source; a fan member operatively connected to the drive shaft; a flywheel extending rearwardly from the power source, the flywheel being positioned adjacent to a rear of the housing; and at least one rear vent formed into the rear of the housing adjacent to the flywheel, wherein rotation of the flywheel draws ambient air into the housing through the at least one rear vent, and rotation of the flywheel generates a cooling air flow that directs the ambient air across the power source to cool the power source during operation thereof.

Debris-collecting systems and bagging apparatus for debris-collecting systems are provided. One bagging apparatus includes a primary bag and a dust skirt configured to wrap around the primary bag. At least an inner face of the dust skirt has an electrical charge. One debris-collecting apparatus includes an input portion, a bagging portion, and a draft inducer for drawing the air and debris through the input portion and to the bagging portion. The bagging portion has a hood, a primary bag removably positioned lowerly adjacent the hood, a dust skirt configured to wrap around the primary bag, and a bagging passage for directing air and debris to the hood from the input portion. The hood has a helical configuration extending from the bagging passage toward the primary bag. At least an inner face of the dust skirt is electrically charged. A frame having at least one wheel facilitates transportation.

The battery-powered backpack blower includes a back support assembly including a back plate configured to permit a user to mount the blower to the user's back, and a volute assembly including a first volute portion and a second volute portion. The backpack blower further includes a housing assembly including a battery assembly and a motor assembly therein, the housing assembly is provided intermediate to the back assembly and the volute assembly.

A manufactured device comprised of a high strength, padded strap with carabiner clips attached onto both ends intended to make a tarp easier to drag under load when attached. The device may be strapped around the body like a chest strap or belt, or drug by other equipment. The device includes a pad to be placed upon the body for comfort whilst using. The device is not meant to be pulled by hand backwards, nor does it consist of anything being tied or secured upon the body. It attaches via the carabiners to the eyelets which are universal and of a standard size on every tarp. Methods for moving debris using the device and a tarp are also disclosed.

A method of reducing or preventing the transfer of pathogens between individuals interacting on artificial turf comprises treating the various components of the artificial turf with a residual antimicrobial coating composition. Treating the artificial turf comprises moving an artificial turf treatment apparatus over the turf in at least one pass, the apparatus being capable of liberating particles of infill material out from between the plastic blades of grass of the artificial turf and spraying the particles with the residual antimicrobial coating composition while the particles are in the air above the turf.
