Self-propelled construction machine

摘要

A self-propelled construction machine comprises a machine frame, on which a working unit is arranged, and comprises a drive unit for driving the working unit. An additive, in particular a urea solution for operating an exhaust gas treatment system, is provided in an operating material tank which is integrated in the fuel tank or water tank of the construction machine. The integration of the operating material tank in the fuel tank or water tank does not necessitate any modifications to the machine frame. The dimensions of the construction machine can also remain unchanged, since the fuel tank does not take up any extra space on the machine frame if the dimensions of the fuel tank or water tank are maintained.
