CAUTION
Do not adjust high idle speed with the air cleaner
removed.
Correct! You don’t want trash sucked into the engine.
Yesterday was my first mow after the adjustments. The performance was much better. It powered through the thick Common Bermuda really well. The grass discharge was farther. And, not a single seed head of Bahia grass was left standing. I was using OEM Gravely blades.
Some people may change the style of blades to achieve the desired results, when the engine isn’t set to the manufacturers specifications.
