A kit for retrofitting a vehicle, such as a lawn mower or tractor, into a lawn care vehicle for distributing liquids for treatment of a lawn, the kit includes a base, a liquid tank, a hose reel, and a fluid flow control system. The fluid flow control system includes a dispensing hose on the hose reel and a hand-held hose. A Y-shape valve fluidically connects the dispensing hose and the hand-held hose to each other and to the liquid tank. The nozzles of the dispensing hose and the hand-held hose have a magnet so as to magnetically mount them anywhere on the vehicle, and the components of the kit may be mounted in various arrangements on the vehicle.

A lawn mower contains: a work unit including a housing having a downward-facing opening and a cutter blade rotatably provided in the housing such that when rotated, the cutter blade cuts grass and generates a transport air flow flowing from the opening of the housing to inside; a grass clippings receptacle configured to receive grass clippings cut by the work unit; a grass clippings transport passage connecting an interior of the housing with the grass clippings receptacle; a shutter device including a shutter configured to selectively open and close the grass clippings transport passage and an actuator configured to drive the shutter; a controller configured to control the shutter device; and a pressure sensor provided in the grass clippings transport passage to detect a pressure in the grass clippings transport passage, wherein the controller is configured to control the shutter device in accordance with the pressure detected by the pressure sensor.

A system for modifying a row unit of a harvesting head, the system including at least one cutting disk, a right angle gear set configured for being drivingly connected to the cutting disk, and a drive shaft between a row unit gear box and the right angle gear set. The system may drive two counter-rotating cutting disks that can be positioned either at near the rear or the front of the row unit. A method for modifying the row unit includes removing existing stalk rolls and housings, installing a cover plate over a gearbox to which the housings were mounted, removing existing trash knives, drilling holes in the row unit frame for mounting the cutting disks, installing the cutting disks.

A blade assembly for cutting roots is installed on a hand-carried weed cutter or hand-carried sidewalk edger. The blade assembly comprises a rear blade configured to support a plurality of blades on the shaft of the weed cutter. The rear blade has a plurality of teeth disposed around its perimeter, and a central opening configured to be received by the shaft of the weed trimmer. A front blade has a plurality of teeth disposed around its perimeter. Stacks of grinding segments are sandwiched together between the rear blade and the front blade, each stack of grinding segments extending partially around the blade assembly at an angle. Each grinding segment has a plurality of teeth disposed along an outer edge of the grinding segment. Spacers without teeth are adjacent to and separate the stacks of grinding segments from one another. The spacers are also sandwiched between the rear blade and the front blade.

An unmanned lawn mower includes a mower body, a cutting module, a wheel module, a camera module and a CPU. The cutting module is mounted on the mower body and configured to weed. The wheel module is mounted on the mower body and configured to move the mower body. The camera module is mounted on the mower body and configured to capture images of surroundings of the mower body. The CPU is coupled to the cutting module, the wheel module and the camera module. The central processing unit controls the cutting module and the wheel module to weed within an area according to the images captured by the camera module and control signals from a handheld electronic device, or the central processing unit controls the cutting module and the wheel module to weed within the area according to the images captured by the camera module.

A convertible lawnmower is provided. The lawnmower includes a housing and a mulching system. The housing includes a discharge opening. The mulching system includes a mounting ring and a shutter ring. The mounting ring is coupled substantially concentrically to the housing and includes an upper surface, a lower surface, and a sidewall that extends substantially axially therebetween. The sidewall is formed with a platform track and at least one installation tab. The platform track extends at least partially circumferentially along an inner surface of the sidewall and each installation tab extends axially from the lower surface. The shutter ring is coupled to the mounting ring via the platform track such that the shutter ring is selectively shiftable between a mulching mode and a discharge mode.

The mounting ring is coupled substantially concentrically to the housing and includes an upper surface, a lower surface, and a sidewall that extends substantially axially therebetween. The sidewall is formed with a retaining groove and at least one installation groove. The retaining groove extends at least partially circumferentially within an inner surface of the sidewall and each installation groove extends axially from the lower surface to the retaining groove. The shutter ring is only coupled to mounting ring via the retaining groove such that the shutter ring is selectively shiftable between a mulching mode and a discharge mode.

According to examples, a modular power tool may include a motor housing including an electric motor, a drive member connected to the electric motor, the drive member being connected to a drive coupler, an extension pole including an input shaft having a first end connector and a second end connector, in which the first end connector is configured to mate with the drive coupler, and an attachment component having an attachment connector and a working implement, in which the attachment component is configured to mate with either of the drive coupler and the second end connector.

Systems and methods for cutting grass and other materials using a disk-shaped cutting web are disclosed. The cutting web has a center portion that is attachable to a rotating shaft adapter. The center portion may be a solid annular disk having a keyed aperture that allows it to be mounted on a spindle of a rotating shaft adapter. The cutting web has multiple strings that are connected to the center portion and extend outward from it in a generally radial direction (away from the center of the disk). The strings intersect with each other to form junctions at which they are joined, thereby forming a web that can be rotated at high speed to perform a cutting function. The strings of the web can have sharp or serrated edges and may be colored to increase the visibility of the web.
