Bulldozer (also known as 114P6H1V0) is an c/6 orthogonal spaceship discovered by Paul Tooke in October 2008. It was the second c/6 orthogonal spaceship to be found that does not involve a dragon (the first one being 274P6H1V0).

The spaceship features a strong central forward spark and a low enough speed, allowing it to run right over some small still lifes and oscillators and continue on unharmed. It emits back sparks as well, which can perturb a glider in various ways when assisted by other c/6 spaceships. With perpetually recycled gliders, a dirty c/6 puffer or even a clean rake is possible.

Variants

As shown below, the front part of the spaceship was found as a self-supporting wick, where the repeatable component can stabilise itself in any of three unique ways, making the spaceship arbitrarily extendable.

The tagalong is only supported by the domino sparks at the back of the spaceship, which means it can also be attached to the back of a pair of bulldozers.
