A mounting and dismounting system for replaceable power sources is disclosed. The mounting and dismounting system is integrated into a vehicle. The vehicle may be an electric vehicle and the replaceable power source may include at least one battery. The mounting and dismounting system includes a lift rack assembly that engages shafts on the replaceable power source to raise and lower the replaceable power source. The mounting and dismounting system also includes a set of retaining members to help keep the shafts in place. The lift rack assembly includes rack members that move in a substantially vertical direction to limit swinging and tilting.

A work vehicle includes a cab, a driver's seat disposed inside the cab, a first steering device, a second steering device, a seating sensor, and a control unit. The first steering device is disposed in front of the driver's seat. The first steering device is configured to perform a steering operation of the vehicle. The second steering device is disposed to a side of the driver's seat. The second steering device is configured to perform a steering operation of the vehicle. The seating sensor detects whether or not an operator is sitting in the driver's seat. The control unit disables the steering operation with the second steering device when the seating sensor detects that the operator is not sitting in the driver's seat.

A control unit (11) that outputs a shift signal to a transmission (4) when the control unit recognizes that the bucket (1) is in a loading position, such that the transmission (4) shifts not to the next-higher gear ratio, but to a further, even higher, gear ratio.

A traction force limiting device for a working machine with a continuously variable transmission that comprises a variator for adjusting the rotational speed ratio of the transmission independently of the torque ratio of the transmission. The traction force limiting device has a traction force interface for providing information to determine a traction force of the working machine, a limit value interface for setting a traction force limit value of the working machine and a control interface for emitting a control signal to the variator. Additionally, the traction force limiting device has a computer unit designed, on a basis of information provided via the traction force interface, to determine the traction force, to compare the traction force determined with the traction force limit value set via the limit value interface, and to control the variator in such manner that the traction force does not exceed the traction force limit value.

A method for testing power of an electric drive system includes setting the electric motor of the electric drive system to a desired speed and applying a brake load to the system. The method also includes increasing the brake load until an engine of the electric drive system is fully loaded. After the engine is fully loaded, the method includes maintaining the brake load until the acceleration remains between the upper predetermined threshold and the lower predetermined threshold for the predetermined period of time, which indicates that the engine has stabilized at full power. Once the engine is at full power, the commanded power of the electric drive system required for stabilizing the engine at full power is averaged, and the average power is compared to a predetermined pass/fail threshold to determine if the electric drive system has sufficient power.

A work implement of a motor grader in which a blade can readily be replaced is provided. The work implement includes a shift cylinder assembly and a blade. The shift cylinder assembly includes a blade shift cylinder and a rail which carries out reciprocating motion with extending and retracting of the blade shift cylinder. The blade is removably attached to the shift cylinder assembly. The blade includes a hook and the shift cylinder assembly includes a hook reception portion. The hook is hooked on the hook reception portion.

There is provided a storage apparatus for documents capable of preventing the storage apparatus from being an obstacle to getting-on/off motions and securing front visibility in good condition. A storage apparatus includes a frame having an opening and wall portions and a lid portion attached to the frame, in which an entrance of the canopy is provided on a left side or a front side of a vehicle body, the frame is fixed to a right side of the vehicle body, the lid portion has a structure in which a right end is attached to the right wall portion of the frame, a left end turns between a position of the left wall portion and a position in a lower direction of the right wall portion, and a holding portion holding the documents is provided in an inner surface.

Disclosed embodiments include power machines having doors with a display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., allowing the operator of the machine to see the displayed information closer to the line of sight with the work area.

A work vehicle includes a work implement. A control system for the work vehicle includes a controller that controls the work implement. The controller obtains a first design topography. The controller determines a second design topography. At least a portion of the second design topography is positioned above the first design topography. The controller generates a command signal to operate the work implement in accordance with the second target design topography. The controller changes a tilt angle of the work implement when at least a portion of the second design topography is positioned below the first design topography.

A control method in a motor grader including a running wheel, an inclination mechanism which inclines the running wheel, an operation portion, and a sensor capable of detecting whether or not the running wheel is at an erect position includes outputting from a controller, a control signal for driving the inclination mechanism in response to an operation command in accordance with a state of operation onto the operation portion and stopping output of the control signal in response to the operation command when the sensor detects the erect position.
