The NetSmartz Workshop Web site is a virtual plethora of information, well-suited for parents, teachers, kids of all ages and teens. Even if this site was the only site on the Web with lesson plans, you'd be good to go. Some of the Internet safety lesson plans offered by NetSmartz include:. The cards come with all kinds of tips, time estimates per activity and extra materials needed for each card lesson plan.
A great resource. Internet safety is a priority, this is a good site to visit as they cover not only lesson plans for students but also items like professional development, curriculum scope and useful accompanying freebies such as posters and letters to parents. Before starting the combine: Disengage header drive. Disengage separator drive Place gearshift in neutral Depress clutch pedal. Always keep your mind on the dangers of driving the combine on public roads. Beside maintaining control of the machine, you must watch for obstacles on the road, pedestrians and traffic.
High speed is the leading cause of accidents. Never drive faster that the road conditions allow for safe operation. Anticipate dangers and slow down to avoid accidents. Make sure you are familiar with local traffic laws. Check the safety flashers and SMV emblems to be sure they are clean and visible. Always lock the brake pedals together.
12 Great Lesson Plans for Internet Safety
If the combine is not equipped with locking mechanism, be sure to depress both pedals at the same time evenly. Applying only one brake, or applying one harder than the other can cause the combine to swerve and perhaps tip over. Be careful when applying brakes when a header is attached to the combine.

The added weight up front can cause the combine to tip forward if the brakes are applied abruptly. Always drive slow enough to allow controlled application of brakes at all times. Always check headlights and safety flashers to make sure they are properly adjusted and in working order. Put the unloading auger in the transport position. Be certain it is not blocking a safety flasher or SMV emblem. On self-propelled combines, never use the header safety support when transporting the machine. Raise the header enough for safe ground clearance, but not high enough to reduce visibility.
On pull-type combines, always use header support when transporting. Towing at transport speeds can be hazardous because of side forces on the tractor when stopping too quickly. Side forces from slowing a combine too quickly may cause a tractor to skid, especially on loose gravel. Slowing down while turning can cause jack-knifing. Slow down before the corner so the towed combine doesn't get out of control. Watch for low power or telephone lines, bridges, buildings and any other obstacles, to make sure you can pass under them safely. Always keep as far to the right of the roadway as possible.
Keep a careful watch to see that you have safe clearance on both sides. Always sit down when traveling at high speeds or going over rough terrain. Be careful when making turns. Make sure that the rear of the combine will clear obstacles when it swings around.
Avoid sharp turns.
Turning too sharply at high speed can cause the machine to turn over. Because the wheels for steering are in the back, self-propelled machines often fishtail when turned too quickly at transport speeds. Steering to the right will whip the rear to the left, and vice versa.
Steering suddenly to the right when meeting oncoming traffic causes the back of the combine to swing out into the path of on coming traffic. Slowing or braking too rapidly could cause loss of some steering control weight on rear wheels. This is most noticeable when driving with a corn head or some other heavy header raised high. In this case, most of the weight will be on the drive wheels. Install rear wheel weights. Keep header as low as possible. Use the variable speed drive or engine throttle to slow the machine.
Reduce speed before you need to apply brakes and always lock brake pedals together. Never depress the clutch pedal or take the combine out of gear to coast down hill. When the combine is moving it is impossible to shift the transmission back in gear.

Always maintain complete control of the combine. The same applies to tractors that are towing pull-type combines. If the combine must be transported over long distances, it is safer to haul it on a large truck or a special low trailer. Never tow the combine at speeds higher than 20 mph. Always keep the transmission in neutral or in the "tow" position, if the combine is so equipped. Never tow a combine equipped with hydrostatic drive.
Towing can cause damage to the drive unit.
Introduction to teaching road safety and lesson ideas
Instead, haul the combine. Never operate the combine if you are ill or sleepy. Operating safety depends on alert, efficient handling of the combine. Wear safety glasses at all times. Wear clothing that fits snugly to avoid catching clothing in moving parts.

Never let anyone ride on the combine unless it is equipped with a passenger seat. A rider's clothing may become entangled in moving parts, or he may be thrown off the machine. Before starting to harvest a field, check it carefully for ditches, fences or other obstacles.
Be aware of weather conditions which present safety hazards. Be especially careful when operating on hillsides. Avoid sharp turns that could tip the combine over. Beware of ditches or obstacles--they are doubly dangerous on slopes. If grain tank extensions are used, remember that the added weight may make the combine top heavy and more subject to upsets. The added weight makes the combine more difficult to maneuver and easier to upset. Always sit down when traveling over rough terrain.
A sharp jolt can throw you from the platform or away from he controls.
Basic safety considerations
Hillside combines are equipped with automatic or manual leveling devices. Hydraulic cylinders act to level these combines on steep slopes. These machines are equipped with a warning signal that indicates when the leveling system has reached its limit. Be especially careful after the device activates. When using the steering brakes, always turn the steering wheel before applying the steering brakes.
Failure to do so can cause the combine to swerve and turn dangerously.
Always keep the machine clean. Field trash around the exhaust system can cause fires. Mud, grease or oil on the operator's platform or ladders can cause falls.
