The road finisher comprises a material hopper for receiving paving material, a screed for compacting paving material, and a main control stand which provides an operating location for an operator on the road finisher. The main control stand comprises a floor area. The road finisher comprises a lighting unit. The lighting unit is no more than 140 cm higher with respect to a vertical direction than the floor area of the main control stand. The lighting unit is arranged such that at least 60 percent of the light output emitted by the lighting unit during operation falls onto the floor area of the main control stand.

An earth working machine (10), in particular a road milling machine, a stabilizer, or the like, having a milling drum (30) that is mounted rotatably on a machine frame (11) and is populated or populatable on its outer circumference with working tools (31); the working tools (31) to come into contact, during working operation, with the ground that is to be worked to remove it; a drive unit (20) drives the milling drum (30) by means of a drive motor (21); an input drive shaft (33) couplable to the drive motor (21) is attached to the milling drum (30); and a ballast element, constituting a kinetic mass (57), increases the kinetic energy of the milling drum (30). The kinetic mass (57) is couplable to or decouplable from the rotatable milling drum (30), or a rotational member indirectly or directly coupled to the milling drum (30), via a shiftable coupling (55).

A ROPS (protective structure) (15) is obtained by coupling upper ends of a pair of leg portions (15a) with a coupling portion (15b) and forming an arc-shaped curved portion (15c) between each of the leg portions (15a) and the coupling portion (15b), and is arranged so as to straddle vehicle bodies (4 and 5) and fixed. A working light (17) is fixed to the left curved portion (15c) via a mounting bracket (19), and a rotary light (18) is detachably mounted by fixing a mounting bracket (20). A protect region (E) formed into an approximately triangular shape is formed by the curved portion (15c) of the ROPS (15), a lateral restriction line (L1) in which a left-side surface corresponding to a maximum width of the vehicle bodies (4 and 5) is extended upward and an upper restriction line (L2) in which a maximum height of the ROPS (15) is extended laterally. The working light (17) and the mounting brackets (19 and 20) are arranged in the protect region (E), thereby preventing an outward protrusion.

A control device may obtain sensing data from at least one sensing device associated with a work machine and may determine, based on the sensing data, a projected path of the work machine and a location of at least one obstacle. The control device may determine that the at least one obstacle is in a portion of the projected path of the work machine, wherein the portion of the projected path of the work machine is associated with an accessory component of the work machine. The control device may identify, based on determining that the at least one obstacle is in the portion of the projected path of the work machine, a potential collision of the at least one obstacle and the accessory component of the work machine and may cause the accessory component to adjust from a first position to a second position to avoid the potential collision.

A road finishing machine comprises a tractor and a screed hinged to the tractor to be towed behind the tractor. At the tractor, a main control platform of the road finishing machine is provided which offers space for an operator and comprises operational controls for controlling functions of the road finishing machine. The main control platform has a roof, wherein a lighting unit with a light source is provided at the roof. The lighting unit comprises a housing which accommodates the light source and has a reflector. The reflector is configured to reflect light emitted by the light source into a working area of the screed so that the working area of the screed is illuminated indirectly.

A construction machine that frequently changes between a forward and reverse direction of movement includes a system and method for operating the machine such that rotation of the operator seat can change the direction and speed of the machine's movement to minimize disorientation by the operator. The machine can be changed from moving in the forward direction to moving in the reverse direction, without changing the position of a propel lever or joystick that is used to control the direction and speed of the machine's movement. Rotation of the seat can be used to proportionally reduce the speed of the machine as the machine nears a threshold for changing direction. The joystick can be a dual axis lever that can move along a longitudinal axis and a lateral axis. The direction of movement and speed of the machine can depend on a combination of the joystick position and seat position.

A road working machine includes an operator's station that is adapted to be occupied by an operator of the road working machine. The road working machine also includes a controller and a safety light circuit that is operatively attached to the controller. The safety light circuit includes a plurality of downwardly directed safety lights that are located so as to provide lighted egress from the operator's station.
