The ejector moves back and forth in the bowl to discharge material, load or unload palletized cargo, and fold the dozer blade. The debris shield protects the hose assemblies and fittings in the lower bowl area. The apron cylinder raises or lowers the apron and dozer assembly. The apron and dozer extensions may be removed for transport, and similarly the dozer/ripper blade latches lock the dozer/ripper blade into the folded position for travel. The vehicle width with the dozer extensions was 125" (318cm). (Picture from TM 5-2350-262-10.)

Armored Combat Earthmover M9 in Campe Lejeune, North Carolina.

The flat track suspension of the M9 is obvious here; it could be adjusted to alter the striking angle of the dozer blade. The blade could be raised to allow the scraper bowl to be filled to increase the weight of the vehicle. (Picture taken 1 Jan 1997; available from the Defense Visual Information Center.)
