MACHINE BODY AND WORKING MACHINE
A machine body including an exhaust after-treatment apparatus that executes a reduction treatment on a predetermined oxide in exhaust gas from an engine using a liquid reducing agent. A reducing agent tank provided at a position distant from the engine stores the liquid reducing agent, and a working fluid tank positioned between the exhaust after-treatment apparatus and the reducing agent tank stores a working fluid having a high temperature at least during operation of the machine. A reducing agent supply line is arranged along the working fluid tank at a position above a level of the fluid stored in the working fluid tank to supply the liquid reducing agent from the reducing agent tank to the exhaust after-treatment apparatus. Accordingly, the liquid reducing agent stored in reducing agent tank is unlikely to be thermally affected by the engine, and the liquid reducing agent flowing through the reducing agent supply line is unlikely to be thermally affected by the fluid stored in the working fluid tank.
