If I understand, your mower has a chain driven wheel that turns a larger
wheel that moves the mower along the ground.

If that's the case, a larger chain driven wheel will make it go faster.

The chain driven wheel is rotating at a constant speed, so it cover a
larger "distance" if it is bigger around, which in turn will cause the
regular wheel to cover a larger distance.

Of course, it will have less "power" to move the mower along if it's
geared higher to go faster...
