The Care and Feeding of a John Deere

We bought a tractor yesterday. With a front loader, rotary brush hog mower and tiller. The smallest one whe could get but still a major purchase. Like buying a second car. We've vowed to each other that we will take care of it and make it last a life time. We'll take delivery next week, get some driving lessons and ask the question: How do you take care of a tractor?
