How to Build a DIY Concrete Mixer

The frame and gears of this DIY concrete mixer are built from 40×40 mm square tubing, cut to size and welded into an inverted V-leg structure with cross braces. One leg rests on two sturdy fixed wheels. The support platform consists of three 20×40 mm tube sections welded together. At the ends, two bolts are welded to act as pivot points on the frame. The motor is paired with two reducers to drop from 2800 to 14 rpm, coupled to a shaft with a plate bolted to the bucket. The entire structure is secured to the platform with a strong tubular support. The bucket lock uses a toothed disc controlled by a pedal. A reclaimed steering wheel is welded to the disc and platform pivot. The front of the bucket rests on two swivel wheels. Inside the bucket, shaped flat bar mixers are bolted in place. For additional garden supplies to complement your projects, explore our range.

Mechanisms from Recycled Parts

The toothed wheel system with an 8 mm pinion on one side of the frame keeps the bucket locked in various positions. It's operated by a pedal that slides through two holes in 20×20 mm angle brackets, 30 mm long, welded to the frame. A spring holds it in place and stretches when the pedal is pressed. This clever recycling approach saves money and reduces waste. For outdoor projects, don't forget to browse our outdoor patio furniture to create a comfortable work zone.
