What causes the rider drive belt to slip on a Simplicity 5101604?

If the drive belt on your Simplicity Lawn Mower is slipping, it might be due to greasy or oily pulleys or belt, so clean as required. Alternatively, the tension might be too loose, so adjust the spring tension. Finally, the belt might be stretched or worn, so replace the belt.
