How Powerful Is The KitchenAid Professional HD Stand Mixer?

If it’s heavy duty, it’s gotta be powerful.

Is it?

The KitchenAid Professional HD (heavy duty) is loaded with a 475-watt motor. But what exactly will 475 watts do?

It’s between what the 325-watt Artisan and the 575-watt Professional 600 series are able to do. 

To determine its true power, we have to look at how well a mixer works with dough.

We’ll find that out next…

How Good Is This Heavy Duty Mixer With Bread?

The mixer has enough power for sticky and stiff dough. It will knead multiple recipes of bread in one go.  KitchenAid says it will handle four loaves at a time, but don’t do it everyday.

If you make bread daily, 3 loaves per batch will keep you on the safe side. Reduce to 2 loaves at a time for difficult bread dough like wheat and sourdough.

But, be warned that it is loud as it is tough. If you have a low tolerance to noise, you might feel you have a jet engine in your kitchen.

How Much Batter and Dough Will Fit The Bowl?

The bowl is 5 quarts. It is the same size as the Artisan series, but is squat like the Pro 600 mixer bowl.

A 5-quart bowl can hold 3 boxed cake mixes. Reduce to two if you will be adding nuts or fruits, otherwise, it will be filled to the brim.

How Well Does It Work With Easy Mixtures?

If the Heavy Duty mixer kneads dough nicely, blending easy mixtures will be effortless.

But does it mix thoroughly and uniformly?

Does it pick up all ingredients?

Like all other stand mixers it does not pick up ingredients 100% of the time.

You have to do some scraping. Want to eliminate it? Get a beater with a flexible edge.

The correct clearance between beater and bowl is essential for thorough mixing. Set it correctly before using. See page 22 of the User Guide for instructions. You can download it here:

Is It A Bowl Lift Or A Tilt Head?

The KitchenAid Professional HD is a bowl lift mixer.

What’s that?

As the term implies, the bowl can be raised and lowered by turning a crank lever.

What’s it for?

Raising the bowl brings the beater, whip, or hook into proper contact with the content. Hence, it must be up before starting any task. Otherwise, no mixing, whipping or kneading will happen.

Lowering the bowl gives you space for manual mixing.

You also must lower it to attach or detach the bowl or any accessories.

How Many Speeds Does it Have

speed-controlIt has 10 speed settings for your various mixing and kneading needs. A soft start features always starts the mixer slow no matter what speed you set it to.

How do you set the speed?

By moving a sliding lever left or right to the desired speed setting. It slides smoothly and is easy to control. So easy that you can sweep and move it accidentally.  Be careful because it’s not pretty if you happen to bump it to ‘fast’ when you’re adding dry ingredients.

What Accessories and Attachments Are Included?

Your purchase of a KitchenAid Heavy Duty mixer comes with the following accessories:

  • 1 pc. Burnished flat beater
  • 1 pc. Burnished spiral dough hook
  • 1 pc. Wire whisk
  • 1 pc. 5-qt. Stainless steel bowl with ergonomic handle

The flat beater is for mixing and beating of moderate to heavy mixtures like cake batters, cookie dough, pastry, biscuits, mashed potatoes,, quick breads and creamed frosting.

The wire whisk is for mixtures that need air incorporated. It must be used to whip cream, egg whites, boiled frosting, mayonnaise and sponge cakes.

The spiral dough hook is for mixing and kneading yeast doughs like pizza, bread and rolls.

Other attachments like pasta maker, ice cream maker, sausage stuffer, etc., are not included. You can buy whatever piece you want as they are sold separately. Some items like pasta cutters and makers are also offered in sets.

Visit this post for a complete list and description of attachments for your Heavy Duty KitchenAid stand mixer.

Secondary Features Of The Professional Heavy Duty

This mixer is also equipped with motor protection, electronic speed sensor and soft start.

Motor protection automatically shuts-off the motor when it is overloaded to prevent it from toasting.

Have you noticed a mixer stall when dough (cookie or bread) becomes denser?

The electronic speed sensor is meant to counter that.  It senses any changes in consistency and adjusts the speed accordingly.

Have you experienced ingredients splattering when you start a mixer, especially if you move to higher speeds right away?

The Heavy Duty KitchenAid mixer always starts slow (soft start) even if you choose higher speeds.

Starting a mixer slowly prevents those unwanted splashes and flour clouds.

What Do Customers Say About It?

We look for ratings. We like seeing those stars. So, how many for this KitchenAid machine?

An average of 4.8 stars from more than 1,000 reviews submitted to KitchenAid. It’s an overwhelming vote of satisfaction.

What do customers like most about it?….Its ability to work dense dough.

They rave that they make more bread now or mix several recipes in a single load which saves them time.

Some folks who are considering the Heavy Duty KitchenAid mixer are asking how it differs from the Artisan. Let’s find that out in the next section.

KitchenAid Artisan vs Heavy Duty

These KitchenAid mixers are both 5-quart models.

You can see  which of their features differ in the Comparison Table below:

Electronic Speed SensorNoYes
Motor ProtectionNoYes

Okay they differ, but which mixer is better?

To answer that, let’s go over every feature that are different and see how each affects their performance and use.


The Professional Heavy Duty has 150 watts more power than the Artisan. Is that significant?

You bet it is.

It makes the Pro HD better at kneading dense doughs. You can make more bread more often with it.

Bowl Lift vs Tilt Head

The motor head of a bowl lift mixer is fixed and locked securely. Hence, it is stable and vibrates a lot less.  It is better for difficult mixtures like yeast dough.

On the other hand, the head of a tilt-head mixer is held in place by a pin that locks and unlocks it.  When the job becomes tougher, the locking pin can loosen. Thus, a tilt-head mixer shakes with dense mixtures.

Refer to this post for a more detailed comparison of a bowl-lift and a tilt-head stand mixer.

Burnished or Coated Accessories?

The KitchenAid Artisan has nylon-coated accessories. They are dishwasher safe. But there are reports that the coating flakes.

Burnished accessories like those of the KitchenAid Professional HD must not be cleaned in the dishwasher.  Otherwise, it will oxidize and produce a grey powder. The same will happen if it is exposed to air for sometime while wet.

The dough hook of the Artisan is C-type while that of the Heavy Duty is spiral.

Which is better?

The spiral dough hook is superior in kneading bread dough. It picks up almost 100% of the mixture.

Which KitchenAid Mixer Is Better?

The first thing you should take into account is: what will you use it for?

The Artisan is great if you bake mostly cakes and cookies, and make bread infrequently. The Pro Heavy Duty is better for frequent bread making.

What Is the Price of the KitchenAid Professional Heavy Duty Mixer?

When you buy a KitchenAid Heavy Duty, you will find that only a few retailers sell them. But Amazon offers the lowest price.

On a budget or trying to save?

You can grab a refurbished unit. But there are conditions.

Firstly, accessories may be generic, meaning they aren’t made by KitchenAid. Secondly,  warranty is only six months.

Want it  brand new?

It carries a 1-year warranty and all accessories are manufactured by KitchenAid.

Is The KitchenAid Heavy Duty Stand Mixer Right For You?

verdictYes, if you will make bread daily.

How heavy duty is it?

Enough to knead a batch of  dough for 2 to 3 loaves of bread.

Labels can confuse. Although it is called “heavy duty” and “professional”, it is not for making tons of bread or for commercial use.

It is a compromise between the Artisan and the Professional 600 stand mixers. It has the bowl size of the KA Artisan and the bowl-lift and secondary features of the Pro 600. Its 475-watt power is between that of the 325-watt Artisan and the 575-watt Pro 600 series.

A brand new Heavy duty unit is difficult to find. Colors are limited.

But here’s the thing….

The 6-quart Professional 600 series is at times cheaper. It is a smarter choice considering that it has more power (575 watts, bigger capacity (6 qt.) and more color choices.


Here’s a  detailed account of my first-hand experience with a Pro 600 stand mixer.

    I bought a flex edge beater for the 475 watt pro and it doesn’t work. Do they make a flex edge beater for this mixer?

      Hello Carolyn,

      Unfortunately, there is no available flex edge beater for the your KitchenAid Pro Heavy Duty.
