Abstract: A working machine includes: a support bracket provided on a machine body and including a boom pivotal support portion and a cylinder pivotal support portion; a boom pivotally supported by the boom pivotal support portion; a boom cylinder pivotally supported at the cylinder pivotal support portion and the boom, and causing the boom to swing upward and downward; a hydraulic hose extended through the support bracket from the rear of the support bracket to the front of the support bracket and connected to the boom cylinder; a first clamp to retain the hydraulic hose on the support bracket; and a second clamp to retain the hydraulic hose on the boom cylinder. The support bracket includes a through hole through which the hydraulic hose is passed in a fore-and-aft direction. The first clamp is disposed rearward of the through hole and forward of the rear end of the boom shaft.

Abstract: A work machine includes an engine, a fluid path via which a fuel oil is supplied to the engine, a first filter provided in the fluid path, a pump provided between the engine and the first filter in the fluid path to suck and output the fuel oil, a second filter provided between the engine and the pump in the fluid path, and a third filter provided between the engine and the second filter in the fluid path.

Abstract: A hydraulic system for a work machine includes a first switch valve and a first return circuit. The first switch valve is switchable between a confluent position and an isolation position. The first switch valve is switched to the confluent position such that a first operation fluid tube is connected to a second operation fluid tube and a first transmission fluid tube is connected to a second transmission fluid tube. The first switch valve is switched to the isolation position such that the first operation fluid tube is disconnected from the second operation fluid tube and the first operation fluid tube is disconnected from the second operation fluid tube.

Abstract: The present invention is intended to provide a working machine allowing to form a large opening angle of an equipment cover while avoiding an obstacle even existing in front thereof. A rotating base is installed on a travelling machine body which includes right and left travelling devices, wherein an operation seat and vehicle equipment are arranged in the right and left, an equipment cover for covering the vehicle equipment is openably and closably provided, and a front lower portion of the equipment cover is pivotally supported on the rotating base via a lateral shaft. The lateral shaft of the equipment cover is inclined rearward from one end which is positioned in a side of the operation seat to the other end which is positioned in a side of a side portion of the rotating base.
