Talk:Bulldozer/Research Development

What about 4WD? Bulldozers are tracklaying vehicles! There are very few wheeled bulldozers around and they are usually only operated on firm ground.

But if the bulldozer is track-type, it's absolutely unnecessary to power more than one wheel per track. Recent discussion about hydro-motors prob working against each other shows, powering two wheels on each side is a potential reason for trouble. Instead give it a well-designed tracklaying carriage.
