My father has a book called Moving the Earth. It's a fantastic book to read for tractor operation, loader work, and general dirt working and earth moving tips and trick's. Yes its a little pricey at around $100 for a book. But I rememebr reading the first edition and have learned alot of very useful tips on tractor operation and dirt moving. Heres a link to it I found on Amazon for anyone who would like to purchase this book. To me the amout of information is priceless compared to these great tips to make jobs go a whole lot smother and ideas of dirt moving I never thought of before.
