General Guidelines Based on Lawn Size and Mowing Frequency

Medium Lawns (100–500 yards) Keep an eye out for signs of dull blades, especially during periods of rapid growth.

Large Lawns (5,000 yards and above) Due to the larger area and potential for tougher grass conditions, frequent checks for sharpness are vital.

Factors That Influence Blade Dullness

Dense grass can dull them much more quickly than softer varieties. Moisture, on the other hand, can cause clumping and greatly increase blade wear. Make sure that no objects from outside get under the mower: sticks, mud or cobbles.
