Depending on where you live, your lawn mower may clog up or it may not. There are different factors that affect whether your lawn mower clogs up or not.
Are you mowing when there is still dew on the grass?
Are you mowing when the grass is wet after a rain?
Are you mowing when the grass is too high?
Are you mowing thick grass?
Do you regularly clean your mower deck?
All of these things will contribute to your mower clogging up quickly. So determine which one that is causing the problem and create a strategy to eliminate this problem.
You never want to mow when the grass is wet. It will wear out your lawn mower blade quicker and clog the deck as well. Regular cleaning is important to keep your lawn mower deck free of rust as well as that wet grass continues to keep moisture on the deck metal.
