Did up this little fueling cart. I don't go through a lot of fuel, and know when it's at a 1/4 tank, the tractor will take the full 5 gal. The electric pump takes about a minute to total drain the 5 gal can.
I got tired of lifting the can to my shoulder height and then spilling / splashing diesel on the back of the seat and tractor. Well worth the $60 on Ebay for the pump setup.
