Did this once. Off the top of my head: Clean it well first and then put the loader up on blocks--SAFELY! and so it doesn't roll. You'll need the extra clearance to pivot the tank down out. Drop the belly pan under the back rear. Look at the parts manual on messicks.com to see what holds it. I'm thinking 2-3 clips/bolts. I'm recalling that the back drops down first. It won't just fall out or in. I recall careful prying, pushing, etc.
