A work vehicle includes: a cab to be boarded by an operator, the cab including a roof; and a first antenna mounted on the roof. The first antenna is positioned selectively at one of a position lower than a topmost portion of the roof, and a position protruding upward relative to the topmost portion of the roof.

A cover configured for attachment to the roof of an operator station of a work machine is disclosed. The cover may include at least one first compartment configured for partially containing a lighting device of the work machine. In addition, the cover may include at least one second compartment configured for partially containing a roof-mounted antenna of the work machine, the second compartment disposed in a generally upwardly-exposed portion of the cover when the cover is attached to the roof. Further, a roof assembly for an operator station of a work machine that incorporates the cover is disclosed. Furthermore, a method of manufacturing the cover is disclosed.

Aspects hereof relate to a control system for a terrain working vehicle having an operator protection apparatus. In some aspects, the control system instructs and ceases an actuation of the operator protection apparatus to and between a raised position and a lowered position.

The invention relates to an operator's cabin of a work machine, in particular of an earth-moving machine, comprising: a housing structure that surrounds a workplace for an operator of the work machine, a front windshield at a front side of the operator's cabin, a front grid that is positioned in its protective position in front of the front windshield, and a roof grid that is positioned in its protective position above a roof section of the operator's cabin. The operator's cabin is characterized in that the front grid and the roof grid can be moved out of their respective protective positions by a rotary movement and/or a translatory movement.

A protection mechanism for a working vehicle includes a roof above an operator's seat and including a cutout extending along a top-bottom direction, and an electric device at least partially located in the cutout. The cutout has a dimension along a vehicle-body-width direction that is uniform or substantially uniform along a front-to-rear direction or increases in the front-to-rear direction. The cutout has a thickness along the top-bottom direction that decreases in the front-to-rear direction. The roof include, in an upper surface thereof, a first groove located on an opposite side of the cutout from the electric device and extending in a direction away from the cutout.

A guard assembly for a canopy of a machine includes a roof portion defining a first end, a second end, and a first length. The guard assembly includes at least two bracket members fixedly coupled to the roof portion. The at least two bracket members define a plurality of first through-holes and a plurality of second through-holes. Each of the plurality of first and second through-holes aligns with a corresponding aperture of the plurality of apertures in the frame member to receive a mechanical fastener therethrough. The guard assembly also includes at least two first support structures spaced apart along a first length defined by the roof portion. The guard assembly further includes at least one second support structure extending along the first length defined by the roof portion.
