FAQ

• How easy is it to change a cassette on a Dennis mower?

  ---

  Changing a cassette is very quick and straightforward—typically taking around 30 to 60 seconds once you’re familiar with the process.

• Do I need any tools to change the cassette?

  ---

  The Dennis cassette system is designed for simple, fast, tool-free or minimal-tool changeovers. Always follow your specific model’s instructions, but generally the process is designed to be quick and hassle-free for regular switching.

• How do I know which cassette to use?

  ---

  Choosing the right cassette depends on the condition of your turf and the time of season. Each cassette is designed for a specific turf task. For example:

  • Cutting cylinders – mowing and finish
  • Scarifiers / verti-cutters – thatch control and grooming
  • Brushes – debris removal and presentation
  • Slitters / sorrel rollers – aeration and drainage

  You can find more information here on the types of cassettes and their roles.

• How often should I change cassettes?

  ---

  It depends on your maintenance routine. Many operators switch cassettes frequently—even within the same week—to match turf needs such as mowing, grooming, or aeration. The quick-change design is intended to support this flexibility.

• What should I check before changing a cassette?

  Before swapping:

  • Ensure the machine is switched off and safe
  • Check for debris or damage around the cassette area
  • Inspect the cassette for wear or dull blades

  • Clean after use (they’re designed to be easy to clean)
  • Regularly inspect blades and wearing parts
  • Replace worn components—all wearing parts are replaceable
  • Arrange grinding/sharpening when needed
• Can I store cassettes separately from the mower?

  ---

  • Makes handling and transport easier
  • Keeps your power unit free for other tasks
    Optional cassette storage stands are also available.
• Will changing cassettes affect machine setup (e.g. height of cut)?
