It's unpolished and includes struggles (a stuck fuel filter, leaving the loader on by mistake), which makes it useful for seeing realistic troubleshooting rather than a clean how-to.
Posted by an owner-operator documenting DIY maintenance on his own tractor, including his own mistakes, rather than a dealer or professional mechanic.
This owner's last service was around 118 to 120 hours, and he did this one at 181 hours, so roughly 60 hours apart in his case.
The owner recommends taking the loader off first, since leaving it on made the fuel filter and other service work much harder to access.
Use a solvent like carburetor cleaner or brake clean on the spot, which breaks down the oil or diesel and evaporates, leaving a minor stain but a dry surface.
The owner says the tractor takes about five quarts, a little less than five, and he put in four quarts before running the engine to fill the filter.
