The mini digger is the only double system and at the moment the most challenging model from Hydraulics4Kids. Operating it with both hands at once presents a challenge that guarantees to keep you occupied for quite a while.

Hydraulics4kids project kits are all laser profiled from Medite, an FSC sourced manufactured wooden board. They arrive flat-packed in their own box with intentionally 'loose' instructions. The challenge is to really learn your build task before you fully complete the build.

Just add water, food dye & fun!
Be prepared to assemble and disassemble before you arrive at the finished piece.
Based on real-life hydraulic machinery but made specifically for small hands.
Suitable for 8 years and upwards.
