I'm not sure I understand your question.When I clicked on your question I was hoping to find an explanatory content but you didn't write anything.That makes your question difficult to answer.
As far as I know,their are two lawn mowers :push mower and riding mower.Most of them have their perks and disadvantages.
Riding mowers are ideal for those with health issues or those who can't stand or push things for a very long time.Being able to sit and upgrading to pedal drive makes cutting the grass more like driving a car.Riding mowers have easy key starts and also sun shades for those sensitive to the sun.
The biggest difference between a riding mower and push mower is attachment.With an attachment, riding mowers can be used for different purposes.They can be used to spread grass seed or fertilizer,break up land with auger.
