Concrete Mixer

Had this mixer for a few years used it only occasionally only when i did patio jobs. The mixer works fine, just it has a small problem. You can't mix more that 1 willbarrow. You can only mix 1 willbarrow at a time because it has no more power Please se Detais of mixer below Scheppach MIX140 Concrete mixer 140L 5908404901 Special features The MIX140 is well suited for narrow to normal construction projects.
