I remember a discussion a long while back somewhere about the differences and why not to use at least certain oil filters on your hydro tractor but I don't remember the specifics.

 Any gurus here that can fill me in ?

Check/Bypass valves and micron size.

Hydraulic systems want filters in the 10-20 micron range. some systems use both

I am unsure what the micron requirements are for Engine oil filter, but I do know a lot of them have a bypass built in to keep oil flowing when the filter plugs up.

I have no idea if the hydraulic filter have the bypass.

If your friends to a NAPA store salesperson you should ask of an old " Filter Interchange & Product Numeric Catalog "  when they get their new ones. There's a wealth of info in them as far as filter sizes , micron , check valve , gasket size ect.    It will have air , fuel oil ,plus  other info along with pictures .
