Initial Startup and Self-Propel Test

What happens here

The fully assembled lawnmower is activated. First, the blade is started by engaging the safety bar and pressing the start button. The mower quickly spins up to full speed. Then, the high lift mode is engaged, and the mower's sound clearly changes, indicating increased blade speed. The self-propel feature is tested at different speed settings (1-5) using the dial and thumb paddle. The mower rolls smoothly, confirming the functionality of its propulsion system.

Goal: Verify mower functionality and test self-propel speeds.
