A man excitedly pushing in lawn mower in the backyard of a house.
A man is driving a tracto
You cannot be pushing in lawn mower in the backyard of a house while driving a tracto. Pushing "a" lawn mower is the proper term, not pushing "in" lawn mower.   Tracto is not the correct word, it is Tractor.
