Help a 5th grader?do you have a book or encyclopedia about lawn mowers?

I am supposed to do a science project and my invention that i am trying to do is a lawn mower that fertilizes and kills bugs at the same time . but my teacher told me i have to do a biblography and i need to do 2 sources . one a book and the other an encyclopedia but i need to know the vloume and pages and the library is closed. so technically i would like to know if you have a book about lawn mower and please list the copyright , volume ,and page.thanks a bunch :)
