It's expected that the new CAT bulldozer will be nearly 50 studs (40 cm) wide and over 60 studs (48 cm) long. A new element has been developed for the chain parts of the bulldozer, and it's going to be wider than the previous chain elements, and it will have a slightly different shape. In addition, LEGO has produced chains in the yellow color for the first time since the first element was created in 2006. A curved 2×2 round brick (part 65473) in black is used as the exhaust, which was implemented as the root element (medium nougat) in the LEGO Ideas Winnie the Pooh (21326) set. The long and medium-sized actuators, which are being produced in black for the first time, are also new elements. Further details are an extensively detailed driver's cab, a fire extinguisher in the rear and also the chain tension can be adjusted manually.

As the new Technic flagship, the LEGO Technic™ CAT D11T bulldozer (42131) will of course also have some power functions to offer as well. You'll be able to operate the bulldozer using the Control+ App on your mobile phone (check Shop@Home for mobile device compatibility). Specifically, the left and right chains can be controlled individually, the rear ripper is adjustable both horizontally and vertically, the sliding plate can be moved up and down, but can also be tilted forwards and backwards; and there is also a ladder which, like the original, can be lowered at an angle.
There are no Official Images of the forthcoming set at this time, but we expect an announcement to be coming towards the end of Summer 2021. In the meantime, if you're looking for something to build, take a look here at all the LEGO Technic™ sets that are retiring by the end of 2021.
