If your mower won't start, check the spark plug for wear or damage, ensure the fuel tank has fresh gasoline, and inspect the air filter for clogs. Additionally, verify that all safety switches are engaged properly.
Before storing for winter, clean the mower thoroughly, remove any grass clippings, and drain the fuel system. Change the oil and oil filter, and check the spark plug. Store in a dry place to prevent rust.

To level the deck, park the mower on a flat surface and measure the height of the blade tips on both sides. Adjust the deck height by manipulating the adjustment rods until both sides are even. Refer to the manual for specific instructions.
Excessive vibration can be caused by an unbalanced blade, loose bolts, or debris caught in the blade area. Check for these issues and address them accordingly. If the problem persists, consult a professional technician.

If uncut patches occur, check the blade for dullness or damage and sharpen or replace it as necessary. Make sure the deck is level and the grass is not too wet or tall for effective cutting.
