obviously, not all cans are created equal, but if you have a can like mine and you can't fill a tractor with a vertical filler neck then it's because the can is smarter than you are. i've had a 5 gal no spill diesel can for several years now and i must say that it's the slickest thing since sliced bread for fueling my tractor. i have a jd770 that fuels through the hood so all i have to do is put the can spout in the fuel fill neck and let it flow. the can automatically stops fueling when the tank is full, so there is no spillage.
the other nice thing is that i don't have to exert any energy to hold the can up while filling. i have to lift the can above the hood like you would for any fill-up, and then i just lower it in the hole. i turn the can totally upside down and because of the safety spout it does not leak at all. i have a much harder time trying to pour into a filler neck from a full old style can without spilling. once the spout is in the filler neck i just have to hold the can from tipping over, which takes just over zero strength to do. the fuel empties, and when the tank level reaches the spout the air supply is cut off and the can stops flowing. as you pull the can out the spout springs shut and there is no spillage.
i've had less than stellar luck with some angled neck safety spouts on cans, but this type can't be beat for filling my tractor. if you have one of the newer tractors with the massive filler necks you can always cut a piece of thin (16ga) plate to fit over the neck and cut a hole in the center to allow the spout to go in.
