There have only been a couple of
bulldozers, but
they are all marvelous sets. All feature tracked drive.
The
856 is really more of a loader with a
raising and dumping scoop,
but can also be built with a blade.
8275
is a motorized, remote
controlled behemoth with a raising blade and ripper. Don't
let the tiny size fool you, 8259 is excellent as well. The newest has an interesting triangular track pattern.
One obvious point of similarity is that every single bulldozer has been
yellow. This is a common color in many Technic heavy equipment
models, although there are some exceptions in
excavators.
Set
856 has great mechanical functions and is
one of
my favorite sets.
But for sheer size and impact, it is hard to beat
8275.
