I'm new to the lego world and want to commend the designers of this set! It is an awesome build, well laid out and it just amazes me with the amount of detail they put into this set. I am halfway done and cannot wait to finish and let my son play with it, he has been helping along the way with the organizing parts for the specific steps. I love the transmission and gear layout it really was fun for us to put them together and making sure they move smoothly. Great jobs guys! KenWas this helpful?

After finishing the merc grab lorry I moved on to this beast and what a fun build it was. Although it's a very easy build (8hrs and I'm no expert) it is a fantastic Lego kit. The only drawback is that it's quite glitchy in that even with the slight spaces as recommended in the manual the wheel tends to stutter round and the wheel doesn't actually pick stuff up you have to manually place things in the buckets. Overall well worth the £200 especially as it towers over the merc arocs.Play Experience4.0Value for Money5.0Was this helpful?

My OH bought the Bucket Excavator for himself, being an avid Technic fan. It took him a considerable amount of time to build, taking a few hours out each night. Like the other reviews have said, this is a beast of a machine. Sadly it does struggle with one powerpack, as it’s a hefty build, but we were expecting that having read up in advance. Everything DID work though. After realising it wasn’t going to fit on our unit with the rest of the Technic (it’s too tall), I dismantled the A model, and built the B model Aggregate Plant instead. I found it quite challenging, being a newbie to Technic, but the results were impressive. The motor functions work extremely well in this build, and it’s also a much more sturdy feeling structure. However, the one downside to the B model is all the leftover Lego. It doesn’t use around a fifth of the pieces for B model, leaving quite a pile to be stored away (or used for a custom build). But it does look great on top of the unit, and both of us got hours of fun out of it to boot!Play Experience4.0Value for Money5.0Was this helpful?

As a seasoned lego builder I have an understanding how to build these Technic sets. This set is really impressive but I doesn't function as it should. The forward/reverse driving is jerky. The rotary bucket assembly jams where the 1/4 ring gears join because the ring isn't rigid enough to maintain a tight circle. The pinion gears that the bucket assembly rides on don't sit parallel to each other causing uneven load on the ring gear. I sent pictures to lego and they are sending new ring gear parts but I doubt this will fix the problem. During the assembly I made sure that all the gears were turning freely with no resistance as required for this type of set. I verified that everything was assembled correctly 3 times and still couldn't get this to work. In the pictures you can see the gear tooth spacing at the connection points of the ring gear are too wide for smooth operation.22 December 2016Allison - Consumer Service Specialist, Consumer ServicesThank you for your honest review.
