Finding auto sound systems that can keep up with the constantly evolving technology of today is a real challenge for many car and sound enthusiasts not only around the nation but also around the world. There was a time in the not so distant past when car stereos that had CD players or CD disc changers where the cutting edge of technology. New technology however has nearly rendered the CD players in cars as obsolete as long forgotten 8-track players. The sad news is that many carmakers are clinging to the old days and only offer something as modern as cassette players as standard equipment for auto sound systems.

I think those days will soon be forgotten, as cassettes are no longer even in mainstream production. You should also find that as CDs are rapidly becoming replaced by MP3s that take up very little space in our cars and homes, one day very soon we may see that music companies have decided it is no longer cost effective to produce CDs and render all music to digital formats. So, what does this mean for auto sound systems? It's actually good news for savvy manufacturers are well as savvy consumers who have their eyes on the future and the growing role technology is playing in our lives and as well as our commute to work.

We've seen a recent introduction of satellite radio to our selection of auto sound systems. These stations offer the allure of no commercial interruptions to your music play in exchange for the price of a monthly subscription. At the moment there are two major companies that offer this service to consumers and each have rather proprietary equipment for their use and installation into your car. They are actually offering some rather tempting offers in order to encourage subscribers. Among those wonderful offers are auto sound systems for your vehicle at less than $100 with a prepaid year of subscription services.

For the satellite radio companies this indicates a constantly growing pool of prospective subscribers and the cost of the equipment is a drop in the bucket when compared to customer loyalty and being on the cutting edge of sound technology. The drawback is that you must decide which service you wish to go with before making the purchase. Also while they offer a very nice auto sound system (bare bones kind of kit that only allows for the radio reception in most cases) at a very sweet price, if you want upgrades such as MP3 compatibility, CD players, CD changers, DVD players, GPS, or any number of other new and advanced technology you will still have to purchase those for your sound system at an upgraded price. There are a few packages that come with these things, but the price is a little on the hefty side. Oh the sacrifices we will make for a more enjoyable daily commute.

Know what your expectations are before you decide to purchase the auto sound system of your dream or you could find that it is more the stuff that nightmares are made of than sweet dreams. Do not live in constant fear that if you buy today you will find something you like better 6 months from now, that is a reality. Technology is growing and evolving at a frightening pace. Find the auto sound system that you like best today and make that your purchase. This is a much better option than waiting around indefinitely and purchasing one just as your warranty expires on your car and it's time for a trade in and another auto sound system.

Tractors are one of the most important agricultural pieces of equipment, but can also be one of the most dangerous. Annually, 300 to 400 Americans are killed in agricultural accidents involving tractors, and 50% of these involve roll overs. Every year farm workers are injured by not following basic tractor safety rules. OHSA states that tractors should have standard seat belts, a standard roll-over protection, protection from tractor fluid spillage, and sharp surfaces protected.

Rails and steps need to be in safe condition to prevent falls from the tractor. When operating the tractor, take safety precautions for your personal well being by pulling your hair back; do not wear clothing or jewelry that is long or dangling. Wear work boots, gloves, also hearing and eye protection. Children and passengers are not to ride on the tractor. Children are injured every year from falling moving tractors.

You need to understand the capabilities, power, safety features and general operating procedures of your tractor. Make sure that your tractor is well maintained, so that you are not trying to repair it in the field. Make sure lights and warning signs are properly functioning, especially if driving on the road. Never refuel your tractor when it is running or overheated. Do not refuel near the gasoline pump, and always carry a fire extinguisher. Ventilate your tractor so that carbon monoxide gas does not effect the driver, especially in a closed cab. Always turn off the engine, when getting off your tractor, putting it in gear and with the safety brakes on. Have children and workers stay clear of the wheels to insure slipping from under them Workers need to take caution when around the machinery in case of flying debris.

Operating a tractor is different than a driving a truck or car. Driving with your wheels spread evenly and far out; will stabilize the weight of your tractor. Popping your clutch can tip your tractor; make sure you understand the gears and how to use them properly. Uneven terrain, ditches, and deep crevices can cause a tractor to rollover. Inclines especially steep inclines can change the center of gravity on your tractor and make it tip easily. Reduce your speed when turning and using a front end loader, both of these can unbalance your tractor. Use the hitch as it was intended and read the manual for weight limits and loads to prevent changing the center of gravity for your tractor. Agricultural workers can be killed or injured when trying to hitch machinery with improper backing of the tractor. Never stand between the machinery and tractor.

When driving your tractor between fields on the roads, be sure that all signals are properly working. Follow all the rules of road, and tractors may not be used on the highways. Be aware of drivers that are impatient with the size and slowness of your vehicle; they may drive erratically to pass the tractor. Never use a tractor for transportation to and from town. Use your tractor for the work it was intended to do, to insure your safety.

Back when folks initially began putting together their own electrical cars they didn't have many cost-effective choices in motors. Regularly the first EVs used surplus aircraft starter-generators as a motor.

the times of plodding electrical vehicles were numbered.
rating in an EV. 'Electric cars are driven by large electrical motors typically rated between 3.5 and twenty-eight h.p.. For those used to gas engines, this may not appear like much power, but the rating systems used for gas engines and electrical motors are so different the numbering system is sort of incomprehensible. Gas engines are rated at their peak hp, electric motors are rated at their continuous hp. The motor installed in Eve is a complicated DC FB1-4001. This is a 9' diameter, 140lb series wound DC motor. I bought is back in 1995 for our first EV and, as long as we don't abuse it, the motor should last for decades. The one part that wears out, commutator brushes, typically last eighty thousand miles and are pretty straightforward to replace.
On the first EV I failed to tighten one of the motor-transmission adaptor set screws and over a period of five years the adaptor worked its way back into the motor faceplate and wore away some of the metal. In the process it damaged the bearing. I found a local electric motor shop to replace it for $100, including parts and work.
You will find more details on our Mazda 626 motor and adaptor page. Most EVs use series wound motors, but you may pick up permanent magnet and AC motors, even experimental wheel center motors.
