I just changed the oil (first time) in both of our machines; and yes, it is a PITA to get to the drain plug, filter housing bolts, etc, but it's done & I'm happy.
Emerson, I think that maybe they changed the bolt pattern on the skid plate, but mine has a pile of bolts holding it on, at least 4 on each side, plus some more in the middle, it's actually a decently beefy skidplate, I was surprised. Goofy to me that they didn't make it a spin on filter, too, and the instructions in the manual (on how to change the oil) are pretty worthless. LOVE the machines, though....I changed the filters & put in just over 3 quarts of Honda 10W40, GN, I think.
