• a drive transmission comprising
• a drum,
• a drive input member that receives drive power from a motor, a first gear driveable by the drive input member, wherein the first gear nutates when driven by the drive input member,
• a second gear engaged with the first gear to provide a rotary drive output, wherein the second gear is drivably connected to the drum, and
• a motor having a drive shaft that drives the drive input member, wherein the drum is positioned substantially on the wet side and the motor is positioned substantially on the dry side.

A drive transmission, comprising:

• a motor;
• a drive input member that receives drive power from the motor and has an axis of rotation, wherein the drive input member is inclined with respect to its axis of rotation;
• a first gear mounted on the drive input member, wherein the first gear nutates about the axis of rotation of the drive input member when driven by the drive input member;
• a second gear engaged with the first gear to provide a rotary drive output, wherein the second gear is drivably connected to the drum, and wherein the first gear and the second gear have a different number of teeth;
• a drum that houses the drive input member, the first gear, and the second gear, and is rotatable about the axis of rotation of the drive input member;
• and
• a casing attached to the motor, wherein the casing houses the drum, the drive input member, the first gear, and the second gear.
