Fun build

Fun build. Like other kits of this magnitude, you will wrestle with attaching parts. Mine was missing stickers, a short call took care of that. If I had a complaint, it'd be that across the line, the scales don't match. I have the bucket wheel, the Volvo truck, the excavator, and I'd love to see them all produced in the same scale. I'd happily buy/ build again if I could get them all in the same scale! Read more

One of my favourite builds!

Thoroughly enjoyed this build and would score it as my top build. Technically fun and challenging, end result automation is good, although the ladder automation is surplus imo. Movement and track adjustment system is great. Would like to see some accessory builds come out such as trailers but understand that might not align directly with the theme. Best I get creative!

Great Grandfather still building LEGOs

I have just started building the Cat D-11. Approximately 12% complete. As always, LEGO has excellent instructions. We are on our third generation of LEGO builders. A family of fun!!! Don't be in a rush to construct the set as fast as possible. One missing piece early on could result in having to take it apart to install the missing piece. I speak from experience on the Volvo Articulated Hauler. Go LEGO!!! Read more

Adult Kid Loves It

This is a fun set! We put it together and this is the funnest way to get snacks from the kitchen! Lol This set is massive but not difficult to assemble, but it is large and barely fits on its shelf. Totally worth it! Read more
