For most rotary (motorized) mowers, I recommend sharpening the blades every 20-25 hours. For a lawn that takes about 45 minutes to mow, that means you should sharpen your mower blades every 26-33 mowing sessions.
Your lawn mower blade is dull. Sharpen the blade twice each season to help maintain a green, healthy lawn. A sharp blade not only cuts blades clean so grass plants recover quickly, it helps reduce your lawn mowing time.
One may also ask, when should I sharpen my mower blades? So in conclusion you don’t need to sharpen your blades every time you cut your grass, however you need to do it more often than you’re probably initially thinking, and a good rule of thumb is every 25 hours of grass cutting time go ahead and invest in putting a nice clean sharp mowing edge on your blade.
Subsequently, one may also ask, can you sharpen blades while still on mower?
Although you can probably do an okay job sharpening them while on the mower, there is no way for you to balance them on the mower.

Standard blades are also referred to as “2-in-1” (discharging & bagging) or “high-lift” blades (because they are designed to create a higher-lifting airflow). 2) Mulching blades generally have a more curved style surface and frequently include extra cutting surfaces along the blade edges.
Are high lift blades better?

High-lift blades have deeper curves on the ends, which create enough suction to circulate and expel the clippings. The higher air flow also helps prevent clogging when mowing tall or wet grass.
