Why Your Cyclone Rake Engine Should Always Run at Full Throttle

Prev Next

A person adjusts the engine controls on a Vanguard power equipment unit.

For optimal performance of your Cyclone Rake, the engine should always be run at full throttle during operation. This setting ensures you get the maximum suction power needed for efficient debris collection.

The Importance of Full Throttle Operation

Running your Cyclone Rake at full throttle isn't just a recommendationβ€”it's essential for proper functioning. When the engine runs at less than full throttle, you may experience:

  • Debris left behind under the mower deck

  • Reduced suction power

  • Poor performance when using extension hoses

  • Inefficient debris collection overall


How to Set Full Throttle

Setting your Cyclone Rake to full throttle is simple:

  • For XR950-PRO engines: Slide the throttle control lever all the way to the left (rabbit position)

  • For Vanguard engines: Slide the throttle control lever all the way to the right (rabbit position)

  • Always check your specific engine's operating manual if you're unsure about controls


Common Misconceptions

Some owners mistakenly run their engines at partial throttle thinking it will:

  • Save fuel

  • Reduce noise

  • Extend engine life

While these concerns are understandable, the Cyclone Rake is specifically designed to operate at full throttle. Running at lower settings will actually reduce efficiency and may lead to clogging issues that can cause more problems in the long run.


When to Reduce Throttle

The only time you should reduce the throttle is when you're first starting the engine or when you're about to shut it down. During actual operation, always maintain full throttle for best results.
