A:AnswerHi ward, KitchenAid made the decision in 2016 to no longer place the spring on the beater shaft on all Classic and Artisan Tilt Head Mixers. By removing the spring and washer on the shaft, it is a benefit as it leaves the beater shaft much easier to clean without the spring. It is also not necessary for the operation of the unit as the tools stay locked without them.
A:AnswerWhite.. It's the "classic" mixer not the artisan series... if you want color spend the extra money: KSM150PSER Artisan Series which has multiple colors to choose from.
A:AnswerI believe it depends on the model.
If you purchase a 4.5 quart, they have colors to select for that;
If you purchase the 5.0 Artisan they have different or additional colors, etc...
A:Answer4.5 quarts. Plenty big enough to make a cake. Most home baking single recipes will fit in this mixer as they were developed for home bakers and this is the mixer that is the most common in the home for over 50 years.
