Editing Freewheel (section)

===Agricultural equipment===
In agricultural equipment an '''overrunning clutch''' is typically used on [[hay baler]]s and other equipment with a high [[inertia]]l load, particularly when used in conjunction with a [[tractor]] without a live [[power take-off]] (PTO). Without a live PTO, a high inertial load can cause the tractor to continue to move forward even when the foot clutch is depressed, creating an unsafe condition. By disconnecting the load from the PTO under these conditions, the overrunning clutch improves safety. Similarly, many unpowered 'push' [[lawnmower|cylinder lawnmowers]] use a freewheel to drive the blades: these are geared or chain-driven to rotate at high speed and the freewheel prevents their [[Angular momentum|momentum]] being transferred in the reverse direction through the drive when the machine is halted.
