Tractor Maintenance Day - Changing Oil and Filters on my New Holland PowerStar 120

Since I've had the tractor for about a year and a half it seems like it's time to get the oil and filters changed. Doesn't seem like a bad job at all, a bit slow since it's the first time I'm doing it and I needed to run out for a couple tools. But priming the fuel system, that's the real time suck in all of this.
