42071 Dozer Compactor is one of the more interesting of the small Technic sets that have just been released: not only is it a vehicle that hasn't been modelled before but it also has a cool and eye-catching colour scheme.
The 171 Parts are packaged in several unnumbered bags. There are no brand new pieces in it but there are several re-colours, most notably the 5x11 panel in dark grey which appears in several 2018 sets, the blue spockets on the wheels and the con. bush 2M fr. + cross axle which LEGO seems to have switched from dark grey to red this year.
This is the first time the wheels, first introduced in 2009 in Power Miners sets, have appeared in a Technic set
The completed model
There's not much to say about construction because it comes together quickly and painlessly.
Once complete, the model looks sweet, thanks in part to the contrast between the blue and orange.
The stickers add a lot to the pleasing aesthetic although they could be omitted and it would still look OK.
As you might expect for a small model, there isn't a lot of functionality. The bulldozer blade can be raised and lowered, shown below in its upper position, and it can be steered using the grey axle jointer behind the cab.
The body is articulated so the steering control twists the front of it to change direction.
Here you can see the control for raising and lowering the blade as well as the articulation joint.
Instructions are provided in the box for the 'B' model, some sort of mine cart, which to me doesn't look particularly appealing.
It's a very attractive model at a 'pocket money' price. The price per piece is a little on the high side compared to other 2018 Technic sets, no doubt thanks to the wheels, so it is probably not a set to buy multiples of for parts.
Otherwise, it's the perfect small Technic model...
