I had a craftsman riding mower gave to me I have had one before and this one will not turn its like turning a truck with now power stearing is there a belt or something that I need to replace??

Hi,
Difficult steering almost always is the result of the front edges of the front wheels/tires being further out than the rear. A situation call toe-out. The proper relationship should have them toe-in by 1/4 - 1/2." Makes all the difference in the world. Look at the rod that is behind the tires and goes from one side to the other for a bend, or possible an adjustment. Could also be the part of the spindle that it attaches to.
Peace,
Clarke
