Here are tips on how to mow a wet lawn without clogging your lawnmower: • Clean your lawnmower after cutting the grass. • Mow your lawn more regularly. • Lift the lawnmower deck while mowing. • When everything else doesn't work, side-discharge instead of mulching or bagging. • Stabilize the fuel in your lawnmower to prevent contamination. • Sharpen your lawnmower's blades.
