Why do tractor trailers need so many gears?
Just to allow them to tug more weight. You would need an insane amount of power to tow those trailers if you only had say 5 gears. Either you wouldn't have enough power, or your top speed would be very slow.
The Short Answer
Just to allow them to tug more weight. You would need an insane amount of power to tow those trailers if you only had say 5 gears. Either you wouldn't have enough power, or your top speed would be very slow. Having more gears allow the driver to start moving the weight using the gears to keep the engine in it's optimum RPM range. Deisels don't have high rev limits like gas engine do simply because of the way they operate. They make gobs of power in the lower rpm range, so increasing a diesels rpm limit would act rally give you less power
