Backhoe loader of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency. Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs
Rear-view mirror a piece of glass that is wedge-shaped in cross section—its front and rear surfaces are not parallel. On manual tilt versions, a tab is used to adjust the mirror between "day" and "night" positions. In the day view position, the front surface is tilted and the reflective back side gives a strong reflection. When the mirror is moved to the night view position, its reflecting rear surface is tilted out of line with the driver's view. This view is actually a reflection off the low-reflection front surface; only a much-reduced amount of light is reflected into the driver's eyes. "Manual
