The Dozer Blade is a vehicle upgrade used by Imperial and Chaos Space Marine armies. It is a common term that refers to a family of frontal hull attachments used by many vehicles throughout the Imperium. Most take the form or a large slab of heavy plasteel mounted atop heavy hydraulic shock absorbers, although some are more rigid “ram bars” and others feature spikes, blades and other dangerous additions. They enable the vehicle to move more safely through difficult terrain by pushing aside anything which could snag on the tracks. Ostensibly designed to clear rubble and push wrecked vehicles, and provide additional armour to the front of the vehicle，vehicle crews tend to use them as improvised weapons. They are cheap and are a common sight throughout the Imperium. 

推土机铲刀是帝国和混沌星际战士使用的载具升级。这是一个常用术语，指的是整个帝国中许多载具使用的一系列正面车体附件。大多数采用安装在重型液压减震器顶部的大块重型塑钢板的形式，尽管有些是更刚性的“防撞杆”，而另一些则具有尖刺、刀刃和其他危险的附加部件。它们通过推开任何可能卡在轨道上的东西，使载具能够更安全地穿过困难的地形。表面上是为了清理瓦砾和推动失事车辆而设计的，并为车辆前部提供额外的装甲，但载具乘员往往将其用作简易武器。它们很便宜，在整个帝国都很常见。
