The name "backhoe" refers to the action of the shovel, not its location on the vehicle[citation needed]: a backhoe digs by drawing earth backwards, rather than lifting it with a forward motion like a man shoveling, a steam shovel or a bulldozer. Confusingly, the buckets on some backhoes may be reconfigured facing forward, making them "hoes". However they are not as effective in that orientation, since the dimensions of the various components are optimized for backhoeing. Most backhoes are at their strongest curling the bucket, with the dipper arm next most powerful, and boom movements the least powerful.
