There is no single way to answer how you could remove blades from a blender. We need to be specific for each blender model or at least a brand/type/category of the blender.
Each type of blender has a different blade assembly. Hand blender blades are connected to the shaft in a unique way, the single-serve bullet models have separate blade assembly heads.
The countertop blenders have two classes, one of them has blades fixed into the container, while the other type has detachable blade assemblies.
How to remove the blade from the blender? (Fix blender blades that are not spinning)
With such a wide variety of blenders available on the market. We have divided the answer to the question into sections according to the type of blender you could possibly have.
All Personal/Single-serve/Bullet blender models have similar blade assemblies so the technique to remove their blades would be similar.
Hand blenders have totally different designs, thus the method to remove the blades on immersion blenders is different too.
Even the countertop blenders do not have similar blade assemblies. The blades on a Vitamix blender are attached to the container.
While in the case of Ninja blenders they are easily detachable.
Other countertop blender specialists like KitchenAid also have separate blade assemblies.
Regular blenders either have blades fixed into the container or separable blade assemblies. Ninja has unique blades called the stacked blade assembly which are the easiest to remove.
How to remove Vitamix blades?
Vitamix has strong blades which are tightly screwed into the container.
To remove them from the jar, there is a wrench called the retainer nut wrench.
The retainer nut is a large plastic/rubber nut that lies below the bottom of the container. The retainer nut holds the blade assembly and the drive socket.
To remove the blender blade on the Vitamix blender, use the retainer nut wrench to unscrew the retainer nut.
To do this, first spread a kitchen towel on the countertop.
Invert the Vitamix blender jar.
Lock the blade removal tool wrench on the retainer nut. Give it a push counterclockwise. This needs some force so it’s better to hold the container under your arm when unscrewing the nut.
Once the nut is set loose, put the container inverted on the towel over the countertop and unscrew the loosened nut by hand.
The blade assembly will fall down once it is detached from the nut.
When you have removed the Vitamix blade, you can either repair it or replace it at your convenience.
