Ground speed is matched to the engines ability to maintain speed while cutting grass.
Smaller engines will bog down quicker and if the blade is not spinning at max speed the grass will not be cut properly
It seems unlikely, considering that there are good reasons to consider that the speed of light is an absolute speed limit in our Universe.
The speed of light (ca. 300,000 km/second) seems to be the speed limit in the Universe. Nothing is known to travel faster than light; it seems likely that travelling faster than light is not possible.
4.5 mower will start and run for two seconds
No. At least, all available evidence seems to indicate that it is not possible to transfer matter, energy, or information faster than the speed of light.
With current technology, that's not possible. At the speed of light, it would take you tens of thousands of years to leave our galaxy. The speed of light seems to be a speed limit in the Universe, and current technology is nowhere near travelling the speed of light.
No, the speed of sound is about 57,000 fpm, depending on atmospheric conditions. Most lawn mower blades move at 10,000 fpm to the highest I have seen is 18,000 fpm.
It is believed that the speed of light is the highest possible speed.
The idle on a Toro push mower can be adjusted by turning the screw located on the carburetor. Turn the screw to the right to gain idle speed and turn the screw to the left to diminish idle speed.
The speed of light seems to be a speed limit in the Universe - it isn't possible to transport matter, energy, or information faster than that. Others think that gravity travels faster; Einstein created a universe with an infinate speed of gravity -- it's in the geometry.

check the plate attached to the engine which has the speed control cable running to it from the front pedal. My mower had a missing bolt which connected the plate to the side of the engine. The cable running to it would move the whole plate. This did not allow the cable to change the speed control arm inside hydrostatic assembly. I have to be careful now with the increased speed and sharp turns. Good Luck
mower carbs built since around the mid nineties are non adjustable, except for idle speed,
