26" X-HD Built - High Torque Low RPM

Hawk Concrete Floor Grinder - made in USA.Direct Drive Gears ( vs. planetary belt-drive):
  • Direct connection from the motor to the grinding head:

    • maximizes energy and efficiency

    • reduces amp draw by avoiding friction loss, wear and ongoing maintenance vs. planetary belt-drive grinders

  • Maintenance is minimal if any vs. constant maintenance and expensive repair cost with a planetary grinder

  • Direct drive connection from the motor to the drive plate eliminates belts and pulleys from breaking (i.e. used in a planetary grinder)

  • Direct- gear drive design optimizes the grinder's weight and rotational speed

  • APPLICATIONS:  HD, High Torque Concrete Grinding, Coating Removal, Scarify Concrete, Polishing, Maintenance.

Wheels-Down vs. Wheels-Up (i.e. Swing Machine):
  • With a wheels-down machine, it takes minutes to master

  • A wheels-up or swing machine, they're harder to control, requires a long learning curve, often taking days to master.

Direct Drive vs. Planetary ~ Know Your Market.  The type of equipment needed starts with understanding the project size and your target market [i.e. concrete polishing vs. coating removal and grinding.]

Concrete Grinders  Can be characterized as planetary or direct-drive.  Understanding the difference between the two technologies will enable you to choose the right grinder to smooth, prep, level or polish a concrete floor.

Planetary Gearbox
  • Gear design allows the grinder to move in a straight line across the floor with relative ease, which means greater flexibility and less struggle for operators

  • Best used on less aggressive jobs such as smoothing out a concrete floor or preparing smaller floors for an epoxy coating

  • Gearbox is spread to 2, 3, 4 and more heads using a series of belts and pulleys

  • The design typically provides more torque during starting and then transferred to the individual heads for increased RPM which is beneficial for polishing

  • Extreme heavy-weight machines, typically 800 lbs. and above.  The weight offsets the faster RPM speed which many prefer for higher-productivity rates on grinding and removal applications.

Summary:  Exceptional for polishing and very large square-footage projects.

Direct-Drive Metal Gears
  • Gear design is a direct connection from the motor to the grinding head which maximizes energy and efficiency while reducing amp draw and avoids friction loss and wear that occurs with an offset planetary gearbox

  • Maintenance is minimal and the purchase price is less because the planetary gearbox is eliminated.

  • Direct connection from the motor eliminates belts and pulleys that are in planetary grinders

  • Design optimizes the grinder's weight and rotational speed while maintaining high torque which a planetary grinder does not

  • Skilled and unskilled users can take advantage of the direct drive / wheels-down design to perform more intensive tasks such as removing heavy mastic or thick layers of paint from a concrete surface.

Summary:  Exceptional for grinding, coating removal, polishing.

  • Maintenance is minimal if any

  • Easy to transport

  • Repair cost is minimal and not expense

  • Operates from a standard 120 volt, 15 or 20 amp circuit

  • Faster walking speeds but due to the path-width and scope of the project, multiple paths maybe required.
