What causes uneven cutting on the TB30R and how do I fix it?

An uneven cut is typically caused by a deck that is not leveled properly, a dull blade, or uneven tire pressure. To correct the issue, perform the Leveling the Deck adjustment, sharpen or replace the blade, and check the tire pressure in all four tires. The front of the deck should be between 0" (level) and 1/4" lower than the rear of the deck. (Page 31)
