• The product label can help you find the exact name and manufacturer needed to locate its SDS.
• Manufacturers and suppliers often provide SDS documents on their websites.
• Use the SDS for the exact product being used rather than a similar product from another company.
• Review the handling, protective equipment, first-aid, and fire information before using a hazardous product.

Resources

• Safety Data Sheets (video)
• Where to Find Safety Data Sheets (SDS): A Complete Guide (website)

Leader Tips

• Connect SDS information with the protective gear and work practices used during the activity.
• Keep hazardous products labeled and stored according to their safety information.

Requirement 2a: Diesel Engine Power

What You Need To Do

Describe how a diesel engine produces power. Cover the basic steps from taking in air to turning the crankshaft.

Helpful Tips

• A diesel engine takes air into the cylinder through the intake system.
• The piston moves upward and compresses the air inside the cylinder.
• Compressing the air raises its temperature.
• Diesel fuel is injected into the hot, compressed air.
• The fuel ignites from the heat of compression instead of a spark plug.
• Burning fuel creates expanding gases inside the cylinder.
• The expanding gases push the piston downward.
• The piston connects to the crankshaft through a connecting rod.
• The crankshaft changes the piston’s up-and-down motion into rotary motion.
• The rotating crankshaft supplies power to the transmission or other equipment.
• Many tractors and other farm machines use diesel engines because they provide strong pulling power.

Resources

• How a Diesel Engine Works (video)
• How Diesel Engine Actually Works? (Animation) (video)

Leader Tips

• Use an engine diagram or actual engine parts to show the main steps.
• Have the Scout trace the path from air intake to crankshaft rotation.
• Focus on the basic power cycle instead of detailed engine design.
• Correct any confusion between diesel compression ignition and gasoline spark ignition.

Requirement 2b: Hydraulic Power

What You Need To Do

Describe how a hydraulic system transfers power. Include the pump, hydraulic fluid, hoses or lines, and the cylinder or motor.

Helpful Tips

• A hydraulic system uses liquid to transfer force from one part of a machine to another.
• Hydraulic oil is the fluid commonly used in farm equipment.
• The engine or another power source turns a hydraulic pump.
• The pump moves fluid from the reservoir into the hydraulic system.
• Pressurized fluid travels through hoses, tubes, or passages.
• Control valves direct the fluid where it needs to go.
• Fluid entering a hydraulic cylinder pushes against a piston.
• The moving piston can lift, lower, push, or pull a load.
• A hydraulic motor uses fluid flow to create rotary motion instead of straight-line motion.
• Fluid returns to the reservoir after passing through the system.
• Hydraulic systems can move heavy loads with smooth, controlled movement.
• Tractors commonly use hydraulics for loaders, three-point hitches, steering, and other equipment.

Resources

• How Does a Hydraulic Cylinder Work? (video)

Leader Tips

• Show the Scout a simple hydraulic diagram or an actual tractor system.
• Have the Scout trace the fluid path from the reservoir to the working part and back.
• Point out the pump, hoses, valves, and cylinder or motor.
• Keep Scouts away from leaking pressurized hydraulic lines.

Requirement 2c: Transmission or Other Power System

What You Need To Do

Describe how a transmission or another power system transfers power. Show how power moves from the engine to the wheels or working parts of the machine.

Helpful Tips

• A transmission carries rotary power from the engine toward the drive wheels or other parts.
• Gears change the relationship between engine speed and machine speed.
• Lower gears provide more torque at the wheels while reducing travel speed.
• Higher gears allow greater travel speed with less torque multiplication.
• Shafts carry rotary motion between different parts of the drivetrain.
• Bearings support rotating shafts and help reduce friction.
• A clutch or similar device can connect and disconnect engine power from the transmission.
• The differential allows powered wheels to turn at different speeds during a turn.
• Final drives can provide another gear reduction before power reaches the wheels.
• Some farm equipment uses hydrostatic transmissions instead of traditional gear transmissions.
• A hydrostatic transmission uses hydraulic pressure and flow to transfer engine power.
• Power takeoff systems, often called PTO systems, transfer engine power to attached equipment such as mowers, balers, and augers.

Resources

• Tractor Transmission System: Common Methods (video)

Leader Tips

• Use a tractor or drivetrain diagram to trace the path of power.
• Have the Scout follow the path from the engine to the wheels or attachment.
• Compare low and high gears using a simple pulling and speed example.
• Include another power system, such as a PTO or hydrostatic drive, when it is available.

• Wear safety glasses while filing.
• Secure the screwdriver firmly in a vise.
• Use a fine or medium hand file for controlled shaping.
• For a slotted screwdriver, keep the end straight and square.
• Keep both sides of a slotted blade even.
• Avoid making the tip too thin because it can bend or break.
• Compare the tip with a matching screw as you work.
• The tip should fit the screw slot closely without rocking.
• Remove sharp burrs left by filing.
• Replace the screwdriver instead of repairing it when the shaft or handle is badly damaged.
