1974 John Deere 110, Kohler 241 starter removal

Me and my dad have decided to remove my starter to replace it, as it just sits there and spins, won't engage, but we can't figure out how to get it out, he suggested removing the engine, but that sounds like a lot of work. We can't get at the bolts underneath the starter, is there a trick to this, or do we really have to remove the engine?
