Combining 12 variable speeds and a powerful torque-control motor, this 450-watt stand mixer provides superior mixing control and maintains speed regardless of the mixing load. The unit ensures thorough, even mixing by offering dual-motor three-way beating action where one motor drives the beaters, each turning in opposite directions and a second motor drives the bowl. The bowl speed increases and decreases automatically as the beater speed is increased and decreased. The stand mixer comes equipped with two stainless-steel bowls: one that holds 4-1/2 quarts and another that holds 2-1/5 quarts. Simply slide the bowl selector lever on the front of the unit to the left when using the small bowl and to the right when using the large bowl.
