Look for a shield on the back blade housing behind the rear wheels of the mower. This shield protects the operator s feet from exposure to the blade and thrown objects. A deadman switch, or operator presence switch, requires the operator to hold the device to keep the mower running. If for some reason the operator releases the switch, the engine is turned off. When placed at the correct location, the switch makes it physically impossible for an operator to hold the switch and reach down to the danger area where the blade is operating.
Some switches also have a braking device that stops blade rotation.
Other solutions Think of the layout of the yard and ways to make mowing safer. Retaining walls can help reduce inclines, and flower beds eliminate the need for mowing in difficult areas. Keep trees pruned properly so that you can see while mowing. Filling depressions or low spots ith soil can help you prevent sprains. Always mow across slopes and inclines when using a walk-behind mower.
