I understand that cherries do not need a pollinator- so you will still get fruit. You may only be thinking it is pollinating it, when it is just producing fruit on its own, but I have had multiple sources show that sweet and tart cherries do not pollinate each other. It is also possible there are other cherries around, they are pretty popular, but I don't know how far in distance the trees can be from each other.
ok well here is a link explaining some pollinating, sounds pretty confusing to my small brain
