Why is it important for the hotel’s maintenance department to keep the blades of the hotel’s lawn mowers sharp?

1. The engines of the lawn mowers will run smoother if the blades are kept sharp.
2. The blades are less likely to warp or crack if they are kept sharp.
3. If the blades are sharp, the grass is cut, not ripped, and is therefore less susceptible to disease.
4. If the blades are sharp, the lawn mowers will use less gas.
