Looks like the right spot to me. I just changed and cleaned my YM226, does seem to do better. It says in the manual to use the tractor and get the hyd oil hot and stop, then the sediment will be suspended (in filter). Before you open the drain plug ***open the dip stick and release pressure in it; if you don't you will get covered in hyd oil, like I did... It should be around 3 to 4 gallons of hyd oil.. When I removed my filter cover it did not have a gasket. I cleaned the surface and installed it back without anything on it. It is not leaking at all.... Have fun working on your TOY!!!
