This past Saturday I performed my first service of my '05 JD 4720 after owning it for nearly four years and putting about 175 hours on it. Service consisted of engine oil/filter, air cleaner element, and diesel fuel filter.
We initially neglected to fill the diesel filter with fresh diesel before remounting, so we lost prime quickly upon start up. We removed the filter, filled it with diesel and re-installed, then pumped the plunger on top of the housing feverishly while starting. A friend who was over performing some dirt work helped out, suggesting a small squirt of ether while starting and pumping the plunger simultaneously should help restore prime. Prime was finally regained once all air was removed from the fuel line between the filter housing and injectors. Once running and confirming by sound that all injectors were active, we proceeded to pull a creosote treated utility pole that had washed down from upstream over the winter. This was pushed up into the bushes out of the way using the edge of the loader bucket.
The last bit of ignorance was spilling about a quart of used oil on our new garage floor, which will be dealt with later.
Every day out or working on the machine results in new lessons learned.
