The  mixer machine makes mixing concrete easy and fast. It has a large hopper that holds four bags of dry cement mix, which means less trips back and forth between the truck and the mixer. The mixer also features a built-in auger that mixes the dry cement mix into a wet slurry in seconds. If you are looking for a concrete mixer that is easy to use, then a quarter bag concrete mixer is perfect for you. These machines were designed to make quick work of mixing concrete. They are also very portable so you can take them anywhere you need to get work done.
