Grizzly Grinders Pappa Bear Floor Grinder
The Grizzly Grinders Pappa Bear is a 15 HP planetary concrete floor grinder designed for large commercial and industrial surface preparation projects. Three 10 inch grinding heads provide an approximately 27 inch grinding path, while the 762 pound machine weight keeps substantial pressure on the tooling for consistent contact with the concrete.
A large planetary floor grinder for contractors who need to prepare, grind, smooth, remove coatings from, or polish larger concrete floors.
Where the Pappa Bear Fits in Your Surface Preparation Equipment
The Pappa Bear is intended to serve as the primary grinder on larger concrete preparation projects. Its approximately 27 inch grinding path allows an installer to cover substantially more floor with each pass than a small grinder, making it better suited for warehouses, commercial buildings, manufacturing facilities, showrooms, and other large floor areas.
Depending on the diamond tooling installed, the grinder can be used for coating removal, adhesive removal, concrete grinding, smoothing, polishing, and preparing concrete before epoxy, polyaspartic, urethane, and other floor coating systems are installed.
Key Features and Benefits
-
15 HP motor: Provides the power needed for demanding concrete preparation and coating removal work.
-

Operating Guidelines
Select the diamond tooling according to the hardness of the concrete, the material being removed, and the surface profile required for the coating system. Machine weight and horsepower are important, but the grinder can only perform properly when the tooling is matched to the concrete and the work being performed.
Use the variable speed control to match the grinder speed to the tooling and application. Aggressive coating removal, concrete preparation, finer grinding, and polishing may require different tooling and operating speeds.
When dry grinding, connect the Pappa Bear to an appropriately sized industrial dust collection system. Proper dust collection helps control airborne concrete dust and removes material generated beneath the grinding heads.
Contractor Tip: Match the diamond bond to the hardness of the concrete. The wrong bond can reduce cutting performance, cause diamonds to glaze, or cause the tooling to wear much faster than necessary.
Warning: The Pappa Bear weighs approximately 762 pounds and requires 220 V / 30 A electrical service. Verify the available power, transportation method, loading equipment, floor access, doorway clearance, and jobsite handling plan before moving the grinder to a project.

Frequently Asked Questions
What size projects is the Pappa Bear Floor Grinder best suited for? â–¾
The Pappa Bear is designed primarily for larger commercial and industrial concrete floors where its approximately 27 inch grinding path and 762 pound machine weight can be put to use efficiently.
What electrical service is required to run the Pappa Bear? â–¾
The Pappa Bear requires 220 V / 30 A electrical service. Power availability should be confirmed before transporting the machine to the jobsite.
How wide is the Pappa Bear Floor Grinder? â–¾
The machine is approximately 28 inches wide and has an approximately 27 inch grinding path. Check doorway and access clearances before moving the grinder into a building.
Can the Pappa Bear remove existing epoxy and other floor coatings? â–¾
Yes. With the appropriate diamond tooling, the Pappa Bear can be used for removal of many existing coatings, adhesives, and surface imperfections while preparing the underlying concrete for a new flooring system.
Can the Pappa Bear be used to prepare concrete for epoxy flooring? â–¾
Yes. Concrete surface preparation before epoxy flooring is one of the primary applications for the Pappa Bear. The diamond tooling should be selected according to the concrete hardness and the surface profile required for the coating system being installed.
Does the grinding speed adjust? â–¾
Yes. The grinding speed is infinitely adjustable from approximately 300 to 1,800 RPM so the operator can change machine speed for different tooling and applications.
How much does the Pappa Bear weigh? â–¾
The Pappa Bear weighs approximately 762 pounds. That weight helps maintain grinding pressure but also makes transportation, loading, unloading, ramps, elevators, and jobsite access important considerations.
What type of dust collection should be used with the Pappa Bear? â–¾
When dry grinding concrete, the Pappa Bear should be connected to an appropriately sized industrial dust collection system capable of keeping up with the amount of dust generated by a grinder of this size.
