Where there's a will there's a way. Odds are you'll have a difficult time finding wheel weights specifically for a 274, as they are extremely rare tractors. It might be worthwhile to explore the possibility of building an adapter if the bolt holes don't line up.
An adapter plate , cut out circular, or even a square shaped plate with studs of bolts would probably work, but would need to fairly substantial 3/4 inch - 1 inch. Same with the studs or bolts.
