I checked my owner's manual - it says the 1480 holds 125 U.S. gallons or 473 litres which works out to 104 Imperial gallons. Not sure about consumption with a 1480 but my 1460 with the 436 engine (cap'y is 92.5 U.S. gal/350 litres/77Imp. gal.) is very cheap to run. I usually run about 12 or 14 hours days on swathed spring wheat (25 or 30 ft. swaths) and can't remember having to add fuel during the day if I started out with a full tank. Never lacked power either.
