A work vehicle includes a cab frame and a vehicle body frame having a vehicle body front portion and a vehicle body rear portion. The vehicle body rear portion includes an upper support frame, and a first support base provided on the upper support frame in a height direction. The first support base supports the cab frame rotatably about a cab rotational axis extending in the width direction. A cover is attached to the cab frame to cover a space provided above the upper support frame in the height direction when the cab frame is mounted on the vehicle body front portion. A first dust intrusion prevention mechanism is configured to overlap with a gap defined by the cab frame, the upper support frame, the first support base, and the cover when viewed in the width direction when the cab frame is mounted on the vehicle body front portion.

Work vehicle with dust intrusion prevention mechanism

A work vehicle includes an arm cylinder configured to raise an arm assembly. A front plate is attached to a vehicle body frame in front of the arm cylinder. A back plate is attached to the vehicle body frame in back of the arm cylinder. A side plate is attached to the front plate and the back plate opposite to the vehicle body frame with respect to the arm cylinder. A bottom plate is attached to the vehicle body frame and the side frame below the arm cylinder. The front plate extends in a reference direction in which the arm cylinder is directed when a work equipment attached to the arm assembly is grounded. The bottom plate includes a downward extending portion extending in the reference direction. The downward extending portion, the front plate, the side plate, and the vehicle body frame define an opening below the arm cylinder.

Work vehicle

An exhaust system includes a vehicle body frame, a bonnet cover provided on the vehicle body frame in a height direction along a height of the vehicle body frame and having a first opening, an exhaust treatment device provided inside a space surrounded by the vehicle body frame and the bonnet cover to treat exhaust from an engine, an exhaust pipe passing through the first opening. The exhaust pipe has an intake port connected to the exhaust treatment device and an exhaust port provided outside the space opposite to the intake port. A muffler cover is provided on the bonnet cover in the height direction, covers the first opening, and has a second opening in a portion facing the exhaust port. A baffle plate is configured to cover a gap between the bonnet cover and the exhaust port in the height direction.

A work vehicle includes a vehicle body frame having a vehicle body front part and a vehicle body rear part, and a cab frame connected to the vehicle body frame and being rotatable about a rotational shaft provided on the vehicle body rear part to be mounted on the vehicle body front part when the cab frame is in a closed state and to be separated from the vehicle body front part when the cab frame is in an open state. The vehicle body rear part has a support frame supporting the rotational shaft and includes a contact plate configured to abut against the cab frame in the closed state, and an engine room to be exposed between the vehicle body front part and the cab frame in the open state. The cab frame has a seal rubber configured to abut against the contact plate in the closed state.

A working machine includes a machine body, an engine provided on the machine body, a radiator to cool a coolant supplied to the engine, a first fan provided on one directional surface side of the radiator, the first fan being rotatable in either one of a first direction to suck external air to an interior of the machine body and a second direction to generate an air flow for discharging air from the interior of the machine body to an exterior of the machine body, and a second fan provided on the other directional surface side of the radiator and configured to be rotated in the second direction.
