One aspect you may not have considered is your turning. Like speeding a car in narrow circles can leave skid marks, making sharp turns with your mower can rip up the grass. Therefore, if you need to make a turn, it's essential to slow down to decrease the stress on the grass. Furthermore, if you need to turn your mower 180 degrees, opt for a K-turn (reverse, then accelerate) instead of a sharp U-turn.
