I you use the proper equipment you shouldn’t have a problem.
Number One: Use a delivery hose that is MADE for Gasoline. It will be so-labelled on it’s outside. That hose will be constructed of materials suitable for gasoline and will be conductive to handle static. Do Not Use hoses not made and labelled for gasoline-delivery.
Two: keep the nozzle of the spigot/handle touching the edge of the filler-neck continuously while pumping gasoline. This will prevent a build-up of static differential.
Three: Stay physically connected/touching the delivery equipment while refueling. Moving away and returning exposes yourself to the possibility of static-differential and discharge. (This is why signs at gasoline stations warn against leaving the pump and re-entering your car and then returning. Your synthetic clothing, the synthetic upholstery of the car, and your movement can create static, and only needs for you to return to grab that delivery-handle awash in gasoline vapors at the filler-neck to have a dangerous spark/explosion.
Regarding item 2, many new tractors have plastic and do not have a conductive filler opening on them. Case in point, our NH TD95D. So there's no metalic place to hold the filler nozzle. Not a big issue for diesel which has a relatively high flash point. Since most newer tractors are diesel, we don't have to worry about this except on possibly lawn tractors which use plastic tanks . Thanks to the OP for bringing this issue up.

It’s still a valid recommendation to keep the filler-nozzle in direct contact with plastic tanks and cans. Some plastics, especially vehicle installed fuel tanks, are made to be “conductive”. Also, any installed tank with a fuel sending-unit will have its’ sensor grounded which will dissipate static.
