Defining Terms

Certain terms must be understood in order to grasp the key concepts of mower safety. These terms will be used throughout this training program.

Power Take Off or PTO is the area of the machine where rotating torque is directly transferred to another machine or tool. In the mower case, the rotating torque is used to turn the mower blades.

Roll Over Protection System or ROPS is attached to some vehicle frames to help prevent the vehicle from upsetting more than 90 degrees, and help prevent the occupant from being crushed if an upset does occur.

Deadman Switch is a device that will automatically turn the machine off if the operator should leave the driver's seat for any reason. It may also be used in the case of an equipment malfunction to turn the machine off.
