Feast your eyes on the largest LEGO Technic set ever made: the Bucket Wheel Excavator. The set features weighs over 13 pounds and contains over 3,900 pieces, so this kit isn’t for the faint of heart.

This is a 2-in-1 model, allowing you to build the Excavator kit, or if you’re bored just convert the kit into the Mobile Aggregate Processing Plant. The set features many intricate details, like hand-railed walkways, giant tracks and a large, detailed cab.

The powering functions allowing you to move the conveyer belts, rotate the superstructure and move the machine into position. Activate the boom to lower the bucket wheel as it rotates, moving the mined material into the (included) mine truck.
