A working vehicle has an upper rotating body and a lower traveling body. The lower traveling body is provided with: a center frame on which a swivel joint is vertically mounted; a right side frame on which a right traveling motor is mounted; a left side frame on which a left traveling motor is mounted; at least one right restriction member and at least one left restriction member, which restrict the maximum width of the vehicle; a right hose guide section having a right opening into which a right hydraulic hose is inserted, and provided to the right restriction member; and a left hose guide section having a left opening into which a left hydraulic hose is inserted, and provided to the left restriction member.

A calibration system is disclosed. The calibration system may include a sensor configured to measure a fluid level in a fluid tank of a machine, an actuator that, when actuated, affects a level of the machine, and a controller. The controller may be configured to: command actuation of the actuator at a current; receive, from the sensor and after commanding actuation of the actuator, information identifying the fluid level in the fluid tank; determine, based on the information identifying the fluid level in the fluid tank, whether there is a change to the fluid level in the fluid tank; and set an initiation current for the actuator at the current based on determining whether there is the change to the fluid level in the fluid tank.

A milling machine is disclosed. The milling machine may have a frame, first and second tracks connected to a first end of the frame, a third track connected to a second end of the frame, and a milling drum attached to the frame. The milling machine may have first, second, and third actuators connecting the frame and the first, second, and third tracks, respectively. Each actuator may adjust a height of the frame relative to a respective one of the first, second, and third tracks. The milling machine may include a damper assembly attached to each of the first and second actuators. The damper assembly may have an accumulator connected to a respective one of the first and second actuators and a control valve for controlling a flow of fluid between the accumulator and the respective one of the first and second actuators.

A motor grader includes a vehicular body, a blade, a front wheel located in front of the blade, two rear wheels located in the rear of the blade, a first sensor which detects a position of the vehicular body as first sensor information, a second sensor which detects an inclination of the vehicular body as second sensor information, a first swing member which rotatably supports both of the two rear wheels arranged in the front and rear relation and is swingably supported by the vehicular body, and a third sensor which detects an angle of swing of the first swing member with respect to the vehicular body as third sensor information. A method of controlling a motor grader includes obtaining the first to third sensor information and calculating positions of the rear wheels based on the obtained first to third sensor information.

A work machine including a machine base mounted movably over an undercarriage, and a hydraulic arrangement which includes a first cylinder configured for operating a working blade of the work machine, a second cylinder configured to vary the width of the undercarriage, a source of fluid at high pressure which is fluidly connected to the first and second cylinders and which is housed in the machine base, and a selection valve which is fluidly interposed between the source and at least one of the first and second cylinders. The valve is housed in the undercarriage.

A control system for a work vehicle, includes a controller. The controller includes a processor a memory device communicatively coupled to the processor, such that the memory device stores instructions that cause the processor to receive a first control signal indicative of performing relocation operations. Furthermore, the instructions cause the processor to instruct an actuator assembly to drive a chassis of the work vehicle in an upward direction relative to wheels of the work vehicle in response to receiving the first control signal, such that a front stabilizer and a rear stabilizer are disengaged from a ground.

A kit for a wheel comprises a hub component in the form of an annular body defining a central opening for receiving a shaft on which the wheel is to be mounted, at least one outer rim component adapted to form a substantially circular periphery of the wheel and a plurality of spoke components adapted to interconnect the at least one outer rim component and the hub component with each of the spoke components being arranged at a respective angular position about the hub component. Each outer rim component is formable from a blank comprises a main body which defines an outer ground engaging surface of the wheel, a pair of strips consecutively attached to one end of the main body in a manner such that each strip is movable relative to the adjacent element about a transverse folding axis, so that the strips can be folded to define a peak projecting outwardly to form a wheel rim with fins.

A work machine including a machine base mounted movably over an undercarriage, and a hydraulic arrangement which includes a first cylinder configured for operating a working blade of the work machine, a second cylinder configured to vary the width of the undercarriage, a source of fluid at high pressure which is fluidly connected to the first and second cylinders and which is housed in the machine base, and a selection valve which is fluidly interposed between the source and at least one of the first and second cylinders. The valve is housed in the undercarriage.

A mining machine includes a base having two drive tracks configured to rest on a ground surface and to move the mining machine along a first direction. The drive tracks each have a length along the first direction between a front end of the drive track and a rear end of the drive track. The mining machine further includes a carbody that extends between the two drive tracks, a turntable coupled to the carbody that defines an axis of rotation, and a stabilizer appendage coupled to the carbody. The stabilizer appendage extends forward from the carbody along the first direction and includes a roller or plate to contact the ground surface and provide stabilizing support during a digging operation. The axis of rotation is positioned closer to the front end of the drive tracks than the rear end of the drive tracks.

A support system for an excavator is disclosed as it may include an extended center frame, a trench support, and/or a mat. The extended center frame may be bolted onto a standard excavator to widen the overall footprint of the machine and reduce ground pressure. The trench support relieves any remaining pressure toward the open trench. The extended center frame enables a larger excavator to straddle an open trench, while at the same time a smaller excavator can dig the shallower depths, thereby increasing efficiencies. By implementing the trench support and/or the mat, it might not be necessary to widen the tracks of the excavator as far, thus further reducing time-related costs. In addition, the trench support may also enhance safety of the trenching operations.
