REVERSE LOCKOUT MECHANISM Data indicates that tragic back over accidents occur each year These accidents usually involve unsupervised children Many times these children have been given rides on the machine and have been trained to view this potentially dangerous piece of machinery as fun rather than being taught how to avoid danger This riding mower has a Reverse Lockout Mechanism This mechanism prevents the mower from being shifted into reverse with the blades running To shift into reverse you must first stop the blades and then shift to reverse It is our recommendation that this mechanism remain functional and the operator of this equipment develop the habit of never backing up with the blades running As the Safety Instructions Indicate DO NOT operate blades in reverse STOP BLADES LOOK AND SEE BEHIND AND DOWN for children pets and hazards before and while backing We realize that this could cause a change to your previous mowing method but we encourage you to adjust to this new system Do not defeat the Reverse Lockout Mechanism If you operate your mower near roadways or use attachments that require quicker shifting to reverse there is an override lever provided This lever can be pushed and held before starting the blades and will allow reverse operation until the blade engagement lever is moved to the OFF position at which time the system will return to its Reverse Lockout mode This feature should never be selecte
