If your lawn mower also has a side discharge, the clump of grass can also accumulate on the discharge opening of your mower forming more clumps of grass as it discharges.

So instead of spreading out the cut grass evenly on the lawn, the clumps of grass cluster together forming piles on your lawn.

Trapped dirt underneath your mower can also encourage rust build-up on the blade and inside the deck.

The deck is the housing of the lawn mower where the blade is attached to. So if you don’t clean up the dirt in the deck immediately, more rust can develop and more damage will happen underneath your mower.

The bad news is rust can also corrode all the metal that’s on the deck.
