It walks through draining three plugs (center and both sides), a useful half-inch extension trick for loosening tight plugs, filling with 80/90 GL5 gear oil, and confirming the level with a dipstick after rocking the tractor. Most useful for RK25 owners doing this service themselves for the first time.

Drain the center plug and both side plugs, let it drain about 10 minutes, then refill with 80/90 GL5 gear oil through the vent plugs and check level with the dipstick.
The video uses 80/90 GL5 gear oil purchased at Rural King, which is what Rural King says to use for the front axle.
Use a half inch drive extension on the back side of the plug, then attach a wrench to it for more leverage, though this trick does not fit the center plug.
After filling, rock the tractor back and forth to let oil settle into the gears, then recheck the dipstick and add more if needed.
