MARSHALLTOWN Concrete Mixers utilize a Quad-Mixing System that uses a four-piece replaceable paddle and blade combination to create four different mixing patterns within the drum for a more consistent mix for your pour. Choose between a 6 or 9 cu. ft. mixing capacity to suit your needs. Both options feature a 25 RPM drum rotation, a frictional handbrake lock, and a drum tilt wheel that allows you to pour from either side of the Mixer. The 6 cu. ft. option is available with your choice of drum lining. Choose between a steel or FDA/NSF/USDA approved non-stick polyethylene drum lining to suit your preference. The 9 cu. ft. option is hydraulically driven, which reduces the amount of noise produced and maintenance needed throughout the tool’s lifetime. Both Mixers are available with your choice of either a 2” Ball Coupler or Pintle-style hitch.
