The present invention relates to a robotic lawn mower. The lawn mower comprises a housing having an upper cover portion and a chassis as a carrying platform; a mowing assembly mounted on the front section of the chassis and having two sets of rotatable cutting tools, and a moving assembly having four moving wheels that are mounted on the sides of the chassis; and a control unit for controlling the operation of the mowing assembly and moving assembly; as well as a power source providing power to the mowing assembly for the rotation of the cutting tools and the moving assembly for driving the lawn mower in any or all directions without necessity of turning the front or head of the mower. The cutting tools are formed of semi rigid and semi flexible material, and in the form of short rod or twisted cables or wires.

A weed trimmer trolley assembly includes a clamp which has a first portion that is closable with a second portion for securing around a pole of a weed trimmer. A swivel is rotatably disposed on the clamp and the swivel is positionable at a variety of angles with respect to the weed trimmer. A pair of legs is each coupled to and extends downwardly from the swivel. Each of the legs comprises a first half that threadably engages a second half such that each of the legs has an adjustable length. A pair of arms is provided and each of the arms is coupled to a respective one of the legs. A pair of rollers is each rotatably coupled to a respective one of the arms to support the weed trimmer and thereby assist a physically limited user with employing the weed trimmer.

The present disclosure relates generally to debris collection machines configured to deposit collected debris directly into a disposable collection bag. The machine can include a collection assembly in communication with a vacuum assembly. The collection assembly can include a support frame being sized and shaped to receive a collection bag. The assembly can also include a cover having a permeable member and a clamping section, the cover being connected to the outlet of the vacuum assembly and connected to the clamping section. The cover can have an open position and a closed position, wherein, when in the closed position the clamping section secures a portion of the collection bag between the clamping section and the support frame.

A hand-pushed power tool includes a tool body including a working assembly, a control unit for controlling running of the working assembly, and a handle device. The handle device includes an operation member and a connecting rod assembly including a first connecting rod connected to the tool body. The first connecting rod includes a first lower rod portion and a first upper rod portion. The first upper rod portion is slidable relative to the first lower rod portion to a retracted position and an expanded position. The handle device further includes a detection device including a first detection element for detecting a telescopic state of the handle device, and a control device mounted to the operation member and electrically or communicatively connected to the first detection element. The control device is configured to control the control unit according to detection information from the first detection element.

A coolant pump assembly having a combined hydraulic drive pump and a coolant circulating pump is disclosed herein, for use in connection with a utility vehicle, such as a ride-on or stand-on mower. Such a vehicle includes at least one combination pump assembly that utilizes a first fluid circuit to hydraulically drive a wheel of the vehicle and a second fluid circuit to cool one or more vehicle components.
