The Inset

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

Crust Buster Extensions
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 Crust Buster 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

Crust Buster 3 Blade
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.

  • Portable and Lightweight

    The Crust Buster 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 Crust Buster 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 Crust Buster 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 Crust Buster creates a “lifting” agitation within your tank.

  • Agitate the Tank

    The high speed rotation of the Crust Buster 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 Crust Buster 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 Crust Buster. We are happy to service your Crust Buster and can provide any parts you may need.
