As the worker was cutting the lawn, he proceeded down a hill, was unable to stop, and slid into the side of a building. Due to the wet ground and the incline, he was unable to back the mower up from the building. At that point he dismounted the mower and attempted to pull it away from the wall so he would be able to drive again. While attempting to move the mower, the worker slipped, entangled his foot under the mower deck resulting in a partial amputation.

The manufacturer had performance requirements on how quickly the engine was required to stop after weight was removed from the seat. There was also a recommendation that the seat interlock be checked weekly to confirm it operated properly by shutting down the mower if weight was removed from the seat.
