Where is the fulcrum and where are the input and output forces applied on a leaf rake?

In a leaf rake, the fulcrum is typically located near the handle, where it pivots when in use. The input force is applied at the handle by the user, who exerts effort to lift or push the rake. The output force is applied at the rake's tines, which interact with the leaves or debris on the ground. This setup allows the user to leverage their effort to effectively gather leaves.
