You know the thing you're holding is a v-groove drive pulley because that's what your owner manual says. But what is a drive pulley, anyway?
A drive pulley is a pulley that is attached to a power source, that when in use puts force on a belt (or cable or chain). The belt is connected to an output, which will then spin. This is called power transmission.
All by themselves, they won't give you the drive to wake up early and use your snowblower and clear the driveway, but used with other components, they'll sure make the job easier!
