Once the deck is level, you’re ready to start mowing.

Remember to adjust the deck height based on the type of grass you’re mowing and your desired cut. By following these simple steps, you can ensure that your Craftsman T140 46 is cutting your grass evenly and efficiently.

Identifying the Adjustment Points

Before you can adjust the deck height, you need to identify the adjustment points on your Craftsman T140 46. These are the levers or mechanisms that control the height of each wheel. Locating them correctly is crucial for a successful deck leveling process. The adjustment points will differ depending on the model year and specific design variations of your T140 46; However, they are usually situated on the underside of the mower deck, close to the wheels.

To begin, carefully examine the underside of your mower deck. Look for levers, nuts, or bolts that appear to be connected to the wheels. These components are likely the adjustment points. One common type of adjustment mechanism is a lever with a release button on top. These levers move up and down, adjusting the height of the wheel.

Another common adjustment point is a set of nuts or bolts located on the underside of the deck, near the wheel. These nuts can be turned to raise or lower the wheel height.
