A mower deck hillside adjustment system includes an angle sensor such as an inertial measurement unit mounted to the mower deck for measuring the angle of the mower deck on the roll axis. The angle from the sensor is used to command a left actuator and a right actuator to raise or lower the left side or right side of the mower deck respectively so each side of the mower deck is at the same height to compensate for tire squat and eliminate step cuts.

The invention relates to an apparatus (10), preferably an autonomous robot apparatus, for mowing grass. The apparatus (10) has a plurality of cutting devices (20) for mowing the grass. The apparatus (10) has a plurality of carrying arms (22) which are arranged offset with respect to one another with regard to the transverse axis of the apparatus (10), and are supported such that they can be pivoted up and down in each case individually, and carry in each case one of the plurality of cutting devices (20). The apparatus (10) has a plurality of supporting elements (24) which support in each case one of the plurality of carrying arms (22) on an underlying surface, and are arranged in front of the respective cutting device (20) with regard to a forward moving direction (V) of the apparatus (10). The apparatus (10) can have the advantage that the leading supporting elements (24) do not push any cuttings in front of them, and a risk of the apparatus (10) being jacked up is decreased.

Mowing systems include a mower and, optionally, a remote control unit such as a handheld unit, between which may be provided 1- or 2-way communications. Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. One aspect relates to monitoring a tilt angle of the mower, and defining or executing different system responses as a function of different first and second conditions that relate to the tilt angle. Another aspect relates to automatic adjustment of a speed setting of the mower's drive system as a function of a power takeoff (PTO) unit of the mower.

Components and features are included in the mower, the remote control unit, or both to enhance the safety, functionality, or user experience of the system's user/operator. Aspects of the invention relate to: an enable switch on the remote control unit that requires activation within a specified time before activating a drive system or PTO unit; sharing diagnostic information between the mower and remote control unit and emitting user-detectable warnings in response to the shared information; reducing a danger level of the system when a proximity between the mower and the remote control unit is too small; and using inclinometers in the mower and the remote control unit to control operation of the mower based on tilt angles of both the mower and the remote control unit.

A radio-controlled mower has a frame, an engine unit, rolling bodies configured to move the frame over an area of ground, a central cutting unit, and side cutting units. The frame and the side cutting units are mutually movable.

A flexible mower deck includes a center deck with a plurality of rotary cutting blades rotated by a belt engaging a driven pulley for each blade. A first wing deck and a second wing deck are pivotably attached to a first end and a second end of the center deck. Each of the wing decks are pivotable between a lowered mowing position and a raised transport position. A height of cut mechanism on each of the first and second wing decks raises and lowers the wing deck and includes a four bar caster wheel level mechanism holding a caster wheel sleeve in front of the wing deck in vertical alignment at any height of cut.

Disclosed are a mover robot system and a controlling method for the same, in which a manipulation of a control screen where a remote control is performed is restricted if a mover robot is located in an area other than a driving area, and a locked screen requesting an input of a preset use code is displayed on a terminal, whereby a display of the locked screen is maintained or released in accordance with the input code.
