LEGO Technic Excavator Get digging with a functional Lego excavator. With the advanced Lego Technic line, skilled builders no longer need rely on their imaginations to drive their creations–Lego helps them build an engine. Peppered with mechanical principles and a dedication to authenticity, these sets don’t simply stack blocks, they use special pieces like beams, gears, pistons, pins, and pneumatic cylinders to build a functioning machine. Build the commanding Excavator from the ground up, complete with cool crawler tracks, rotating cab, and adjustable knobs to control the all-important arm and bucket. If you’re looking for a more compact workhorse, rebuild the excavator into a versatile tractor. This 286-piece set includes assembly instructions with detailed color diagrams for building both machines. Blend with other Lego Technic playsets (sold separately), or simply rearrange the pieces for a truly customized machine. –Heather Lyndon
Customer Review: Not the best design
I’m a big fan of Lego and Lego Technic. This is an otherwise interesting set that is beset by two problems: the track undercarriage is a bit flimsy and the worm-gear on the arm is too weak to drive both the middle and outer arm segments. With extended play, I expect the 8-tooth gear on the worm to fail. This set has been discontinued so prices vary wildly. You may find Lego’s more recent excavator, #8294, to be a better value proposition. The new model is larger and mitigates 8419′s shortcomings with new tracks and two linear actuators.
Customer Review: Good value, hours of fun
The instructions were a little less than clear with respect to using black or grey peices, but everything came together nicely. My color boo-boos resulted in a custom look.
