Keep all shields and cover in place. Stop the tractor engine and wait until all moving parts have stopped before leaving operator′s station to adjust, lubricate, clean or unclog machine. Never hand feed material into machine. Do not lean against, sit or stand on cutterbar cover or its supporting framework. Make certain everyone is clear of machine before starting tractor engine or beginning operation. Do not operate mower with cutterbar raised to vertical (transport) position. Always operate machine at rated speed. Drive slowly over rough ground.
Keep Riders Off Machine
Safety - Keep Riders Off Machine Keep riders off. Riders are subject to injury such as being struck by foreign objects and being thrown off of the machine. Riders also obstruct the operator′s view resulting in the machine being operated in an unsafe manner.
Handle Fluids Safely-Avoid Fires
Handle Fluids Safely-Avoid Fires When you work around fuel, do not smoke or work near heaters or other fire hazards. Store flammable fluids away from fire hazards. Do not incinerate or puncture pressurized containers. Make sure machine is clean of trash, grease, and debris. Do not store oily rags; they can ignite and burn spontaneously.

Prepare for Emergencies
Be prepared if a fire starts. Keep a first aid kit and fire extinguisher handy. Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.
Handle Chemical Products Safely
Direct exposure to hazardous chemicals can cause serious injury. Potentially hazardous chemicals used with John Deere equipment include such items as lubricants, coolants, paints, and adhesives. A Material Safety Data Sheet (MSDS) provides specific details on chemical products: physical and health hazards, safety procedures, and emergency response techniques. Check the MSDS before you start any job using a hazardous chemical. That way you will know exactly what the risks are and how to do the job safely. Then follow procedures and recommended equipment. (See your John Deere dealer for MSDS′s on chemical products used with John Deere equipment.
Avoid High-Pressure Fluids

Section 10 - GENERAL INFORMATION
Group 05: Safety
Escaping fluid under pressure can penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure. Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids. If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.
Stay Clear of Rotating Drivelines
Entanglement in rotating driveline can cause serious injury or death. Keep tractor master shield and driveline shields in place at all times. Make sure rotating shields turn freely. Wear close fitting clothing. Stop the engine and be sure PTO driveline is stopped before making adjustments, connections, or cleaning out PTO driven equipment.
