LEGO Technic Bulldozer (42028): Alan’s Build Diary

Alan’s build diary: LEGO Technic Bulldozer (42028)

Alan sent nine photos covering the build from bare frame to finished model. That kind of step-by-step record is worth sharing properly, so this post walks through each stage in order.

The 42028 is a 2014 set, 1,167 pieces, classic CAT yellow. Front blade that lifts via an Ackermann push mechanism (push the exhaust pipe forward and the blade rises, clean top surface, no visible lever). Working ripper claw at the rear. Rubber tracks on both sides. The blade mechanism is one of my favourites in the Technic library for how tidy it is, especially for a set this old.

Early stages

Alan’s photos start with the internal frame going together before any panels go on. This is the part most builds skip documenting, and it is the most useful bit if you want to understand how the blade mechanism sits inside the chassis.

The blade mechanism

The front blade lifts via an Ackermann push mechanism connected to the exhaust pipe on top. Push it forward and the blade rises. No levers poking through the roof, no axle breaking the surface. For a 2014 set this is clean engineering, and it still holds up.

Mid build

By the halfway point the track assemblies are on and the shape of the machine is clear. This is where the blade frame is visible before the yellow panels close it off.

Completed model

The last three photos show the finished model. Both working features in these shots: blade raised, ripper claw lowered at the back. 1,167 pieces, nothing wasted.

Alan has worked through enough of the library now that his photos are useful in a different way to product shots. They show the kit as a builder actually sees it: on a table, built in normal light, with the little mechanical details doing the talking.

If you have built Bulldozer and spotted something I have missed, send it over. The member posts are better when they feel like a record of what people are actually building, not just a list of sets we happen to stock.
