wheels pitched out, hard to turn.

my craftsman lts2000 model #217289070 rideing mowers tires are pitched out like this \ / . i dont know how i did it other then hitting a few trees and stumps. each wheel has what they call a drag link bar that goes back to a gear controlled by the steering wheel. everything look fine. i dont see anything bent. there is no tie rod on the wheels. each wheel is independent. when i straighten one wheel the other is pitched. can anyone help.
