Identifying the Cause: Fertilizer Slick

What happens here

The presenter explains the root cause of the unexpected slipperiness: a recent application of fertilizer by a third-party company. He describes the chemical as leaving an 'oily slick' or 'Teflon' coating on the grass, which drastically reduced the traction of the mower tires. He mentions that even the fertilizer technician struggled to walk on the treated hill, indicating the extreme slipperiness.

Goal: Understand the cause of the dangerous traction loss.
