It is upsetting that you are experiencing this issue.
There is no adjustment for the tension on the PTO engagement lever. If it were made looser, that may allow the belt to slip as it would not have enough tension on the belt.
There are other alternatives for you that you may want to consider, such as a different mower with an electric PTO clutch, these you just pull a button up to engage the clutch and push the button in to disengage the clutch.
Good luck.
