The present disclosure is related to a machine which includes a chassis, a dump body supported to the chassis, and an electric drive system. The electric drive system includes an engine, a generator connected to the engine, a rectifier electrically connected to the generator, an inverter electrically connected to the rectifier, an electric motor electrically connected to the inverter, and a retarder arrangement configured to receive current from the inverter while a brake is applied. Further, the retarder arrangement includes a resistor grid configured to dissipate heat when the current is received from the inverter while the brake is applied. Moreover, the resistor grid is disposed inside an oil bath provided underneath the dump body.
