Abstract
A cold planer is disclosed. The cold planer may have a frame, a drum rotatably mounted to the frame, and a gear box connected to the drum. The cold planer may also have a drive pulley connected to the gear box, a primary motor, and a drive belt connecting the primary motor to the drive pulley. The cold planer may further have a service pulley connected to the gear box, a service motor, and a service belt that connects the service motor to the service pulley. The cold planer may additionally have the gear box being configured to transfer motion from the drive pulley and the service pulley to the drum.

A cold planer, comprising:
- a frame;
- a drum rotatably mounted to the frame;
- a gear box connected to the drum;
- a drive pulley connected to the gear box;
- a primary motor;
- a drive belt connecting the primary motor to the drive pulley;
- a service pulley connected to the gear box indeiendent from the drive pulley;
- a service motor;
- and
- a service belt connecting the service motor to the service pulley,
- wherein the gear box is configured to transfer motion from the drive pulley and the service pulley to the drum.
A cold planer, comprising;
- a frame;
- an engine supported by the frame;
- a battery supported by the frame;
- a drum rotatably mounted to the frame;
- a gear box connected to the drum;
- a drive pulley connected to the gear box;
