A work machine comprises a vehicular body having a first foothold and a traveling apparatus attached to the vehicular body. The traveling apparatus has a crawler belt. The first foothold is disposed above the crawler belt and has a working deck. The vehicular body is provided with at least one liquid replenishing port (e.g., at least one of a first liquid replenishing port, a second liquid replenishing port, and a third liquid replenishing port). In a top view of the work machine, at least one liquid replenishing port is disposed in an area of the vehicular body inner than the working deck.

A work machine includes a vehicle body, a work implement, an attitude sensor, an object sensor, and a controller. The work implement is movably attached to the vehicle body. The attitude sensor detects the attitude of the work implement. The object sensor is attached to the work implement. The object sensor detects an object in a periphery of the work machine, and outputs a signal indicating a presence of the object. The controller sets a detection determination range of the object sensor. The controller determine the presence of the object in the detection determination range based on the signal from the object sensor. The controller calculates sensor attitude data including at least one of a position and an orientation of the object sensor, based on the attitude of the work implement. The controller modifies the detection determination range in accordance with the sensor attitude data.

A work machine component including a cavity formed in the component and having an extension axis, an opening for the cavity placed at an outer surface of the component, a support body having an axial extension axis parallel to the extension axis of the cavity and inserted in the cavity. The support body includes, at a first axial end, a top surface and at least one housing seat configured to receive a wear sensor. The housing seat includes a top wall placed at a distance along the axial extension axis from the top surface of the support body. A wear sensor is housed in the housing seat.

A tractor front linkage quick attach coupling system for interlocking a tractor to a tool front linkage assembly. The coupling system comprises linkage assembly anchoring arms engaging complementary tractor inclined ramps. The arms have notches engaging upper rim members and lower cam members. The cam members are movable between arms/ramps locking/unlocking conditions. A cam member release preventing safety device is provided, to prevent accidental release of the coupling system. This safety device includes sliding stops, over-center compression spring mounted connector rod members, a transverse link, a push link and a hand lever for deactivating the safety device.

An excavator machine with a side mounted silt fence installing tool mounted below the swivel. The excavator has a swiveling and articulating tool and an operator's seat above the swivel. An articulating arm is attached above the swivel so the operator may operate swiveling and articulating tool in a coordinated way with the silt fence installer to accomplish a job more efficiently than it could be accomplished using tools separately mounted one at a time.

An apparatus for a bulldozer that makes the process of controlling a wildfire safer and more effective. The apparatus includes a large capacity water tank that can be mounted to a rear of dozer using a frame. A pump can draw water from the water tank and pump the water at a high pressure. One or more hose reels can also be provided. Strategically positioned sprayers can spray water to nearby surrounding, in particular, on the Fireline made by the dozer. A major safety feature is a remote controlled monitor mounted on the front of the dozers can spray water directed by the operator can protect the dozer from fire as well as fire personnel if a fire comes at the dozer or fire personnel.

A work machine includes a vehicle body, a support member, a blade, a rotation angle sensor, an object sensor, and a controller. The support member is connected to the vehicle body. The blade is rotatably supported by the support member. The rotation angle sensor detects a rotation angle of the blade. The object sensor detects an object around the work machine and outputs a signal indicating a presence or absence of the object. The controller is configured to set a detection range around the work machine. The controller is configured to determine the presence or absence of the object within the detection range based on the signal from the object sensor. The controller is configured to set the detection range according to the rotation angle of the blade.

The present disclosure discloses a rotary frame and a grader, and relates to the field of a grader. The rotary frame includes: a rotary ring, provided with a recessed portion and an opening; a first connecting piece fixed at the periphery of the rotary ring, one end of the first connecting piece being attached to the periphery of the rotary ring and the other end of the first connecting piece being separated from the periphery of the rotary ring; a second connecting piece, the second connecting piece being also fixed at the periphery of the rotary ring, and one end of the second connecting piece being attached to the periphery of the rotary ring and the other end of the second connecting piece being separated from the periphery of the rotary ring; a supporting base fixed on an inner wall of the rotary ring and located in the recessed portion.
