A mower system comprising a powered mower, a connecting device connected to the powered mower and an attachment connected to the powered mower through the connecting device for conducting specified function during the operation of the mower system. The connecting device includes a mounting assembly mounted to the powered mower and a base rotatably mounted to the mounting assembly for driving the attachment being rotated together with the base in a horizontal plane relative to the powered mower. The utilization rate of the powered mower is effectively improved because other working functions can be conducted by the attachment which is connected to the powered mower through the connecting device.

A network of modular, multitier pool mobile units, that wander around and under water of a swimming pool. The pool mobile units monitor for safety, emergency and accident related events and undertake appropriate actions to provide care and protection for swimmers, family members and bystanders. They scrub and clean the swimming pool bottom and wall surfaces and emit chemical agents to sanitize the swimming pool water. A central server provides safety monitoring, help for drowning swimmers, and emergency and accident supports.

Disclosed is an autonomous robot to remove pathogens from a target area such as a grass field, turf field, or yard. Embodiments include an ultraviolet light subsystem that generates ultraviolet radiation operable to remove the pathogens from the target area as the autobot advances along the coverage path.

A work vehicle for managing lawn while traveling includes a positioning module for outputting positioning data, a self-vehicle position calculation section for calculating a self-vehicle position based on the positioning data, an activity determination device for determining activity of the lawn, and a lawn condition information generation section configured to generate lawn condition information by correlating the activity with the self-vehicle position as a determination point of the activity.

A mower-conditioner includes first and second conditioning rolls, adjustment assembly, and a linkage. The adjustment assembly includes a first member having a first helical surface and a second member having a second helical surface in contact with each other. The linkage is coupled between the at least one adjustment assembly and the first conditioning roll. The rotation of the at least one adjustment assembly about a pivot axis causes the first conditioning roll to move via the linkage, which adjusts the distance between the first and second conditioning rolls.

In accordance with an example embodiment, a mower-conditioner may include first and second conditioning rolls, at least one eccentric, and a linkage having a lever. The first and second conditioning rolls are spaced apart a distance. The at least one eccentric is coupled to the mower-conditioner. The lever is coupled between the eccentric assembly and the first conditioning roll. The rotation of the at least one eccentric about a pivot axis causes the first conditioning roll to move via the lever, which adjusts the distance between the first and second conditioning rolls.
