learn about the crust buster


The Power Head

A dependable and easy to start 2.5 hp motor with a high speed, durable transmission engineered with cold form, heat-treated gears encased in an all ball-bearing gear case.


The Inset

CrustBuster shafts are assembled to the power head with 3/8” allen screw. An allen wrench is included with the CrustBuster for Power Head removal or adding additional shaft extensions.


Throttle Assembly

The throttle assembly is easy to grip with the safety start switch, kill switch, and throttle all located on one assembly for ease of operation. It also fits directly in the Buster Brackets.


Shaft Extensions

Shaft extensions are available in 2, 4, 6 and 9 foot lengths. The standard shaft length is 80 inches. The extensions allow the CrustBuster to be used in deeper tanks or hard to reach areas.


Two Blade Design

The 2 blade fold down propeller fits through a 4 inch pipe. Once through the pipe the blade expands to 13 inches in diameter during operation. This is our most popular configuration.


Three Blade Design

The 3 blade propeller is non-collapsible and requires a 12 inch diameter hole or larger. It is interchangeable on the standard shaft and is a great candidate for car wash pits.

how to save time and money

Portable and Lightweight

The CrustBuster is a portable lightweight machine designed to agitate and mix up septic tanks, grease traps and car wash pits. It will circulate and agitate the crust, liquids, and solids into a total liquid form and make your job easier.

Field Tested

The CrustBuster has been field tested and proven to mix a 1000 to 2500 gallon residential septic tank in 5 minutes or less. It is also the perfect machine to bust the crust in those tough and time consuming grease traps or agitate car wash pits.

Saves Time and Money

The CrustBuster is a septic tank agitator that, when used on your job, will save you time and money. Through the use of engineered blades and high-power shaft rotation the CrustBuster creates a “lifting” agitation within your tank.

Agitate the Tank

The high speed rotation of the CrustBuster allows the tank crust and solids to agitate and mix into an easily pumped slurry. The rotation of the blade lifts and removes solids and chunks off the bottom of the tank while pulling the crust off the top.

Easy to Use

The CrustBuster actually pushes back at the operator when used. No back strain, no muscle – just results. It produces an easily pumped mixture, without back-flushing, that also saves you wear and tear on your vacuum pump and equipment.

Supported and Serviceable

We have been in business over 20 years and are committed to helping you do your job easier and cheaper. We stand behind the CrustBuster. We are happy to service your CrustBuster and can provide any parts you may need.

What Others Have to Say About the Crust Buster


The Best Investment we Have Made

As the owner of 2 of your crust buster machines, we are happy to say they are the best investments we have made since we started our business. The days of back flushing, using a rake or a 2 x 4 for cleaning the tank are old school.

A Tool that is Really Worth Something

Every so often a tool comes onto the market that is really worth something. Your Crust Buster is indeed that tool. My corporate headquarters purchased one for us and sent it over to me with no knowledge of what to do with it. Well, within the first day my men knew they had a winner of a tool.

The Crust Buster is the only tool I would not be without

Awesome piece of equipment! I don't know how I've worked without it. I've been cleaning grease traps and septic tanks for just over 10 years and think the Crust Buster is the only tool I would not be without. The crust Buster will mix even the thickest of tanks with ease, saving time, wear and tear on our pump truck, and also saving our backs. We even like the Crust Buster so much we recommended it to one of our competitors.

This little machine has made our life so much easier

This little machine has made our life so much easier. For example, every winter we seem to pump a lot of car wash pits, we used to hate them, but this Crust Buster has made the job so much simpler we even started to take on more car washes - when we used to turn them away! Also, grease traps and septic tanks that have not been pumped on a regular basis go much easier with the Crust Buster.

We Can ixM a 1500 Gallon Tank in 5 Minutes

Just a note, being 6' 9" the extensions you offer for the shaft save me from bending over, makes mixing tanks easier and also allows access to the back of the tank. Any pumpers that do not use this machine are still in the old school of thought. It makes our job easier and we can mix a 1500 gallon tank in 5 minutes even with a two foot scum cap. And with the option of the collapsible propellers we can go down smaller ports and still get the same effect.

This Tool Saves us about 35 minutes per job

We have estimated that this tool saves us about 35 minutes per job. My only problem to date is that my men dispute every morning about who will get to use the Crust Buster that day.

We will be ordering our second Crust Buster

We will be ordering our second Crust Buster in the next month or so to accommodate our other pump truck, so all trucks have this wonderful little machine available on all jobs. Thanks so much to you and your company for creating this wonderful piece of equipment to make our job that much easier and a more professionally finished job. We love the Crust Buster and our customers do too. I would highly recommend the Crust Buster to anyone in this field.
