If you have ever noticed while mowing that the paths of the mower are uneven, this can be one of two things. One is improper tire inflation and the other is that the mower deck is out of level placement.
The first can be remedied by properly inflating the tires. Check you manual for recommendations, as the front and rear tires usually require different pounds of pressure.
For the second, the deck needs to be leveled. Once you have inflated the tires as stated above, you will need to be need to be sure the mower is on a hard flat surface, such as a driveway or garage floor. You will need a ruler to check the blade heights from side to side, as well as front to back. Rotate the blades to where the tips are at 90 degrees with the mower. Check tip height with the ruler. If they are not even, the deck can be leveled with adjustments found on each side at the back of the deck. Once this is done, rotate the blade 180 degrees (horizontally) with the mower in order to check level front to back. If the blades aren't level, this adjustment is usually made at the front of the deck. Your mower manual should show you where to adjust the deck.
By taking the time to do these simple tasks, you will have a more perfect mowing machine, as well as a more beautiful lawn.
