A small wind-up mechanical model of a bulldozer with an on/off switch for each track, and a speed regulator
A small wind-up mechanical model of a bulldozer with an on/or switch for each track, and a speed regulator.
The B-Dozer has a removable bucket and an opening hood. The model can travel about 2.5 meters.
The B-Dozer has four levers. The on/off lever in the middle starts the engine. Two larger levers engage and disengage each of the tracks. If you disengage both tracks, the bulldozer will stand still and the engine will run idly. There is another slider on the side near the seat that is a speed control lever. It changes the speed of the model.
When designing the model, we took into account the difficulties we had with the Marvel Tank model and made a completely different mechanism, a different type of track, and added a way to adjust the tension of the tracks.
