This overhead view provides a look into the scraper bowl. 1. Apron and dozer assembly. 2. Headlights. 3. Stowage box. 4. Ejector. 5. Floodlights. 5.1. Debris shield. 5.2. High-pressure filters. 8. Track. 9. Apron cylinder. 10. Track wear plates. 11. Apron and dozer extensions. 12. Dozer/ripper blade latches. 12.1. Ripper blade.
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.)
The rear of the machine is drawn here. 13. Rear floodlights. 16. Upper apron lockpins. 18. Dozer lockpins. 19. Tiedown shackles. 20. Roadwheels. 21. Sprockets. 22. Tiedown brackets. 23. Tow shackles. 23.1. Hull protective plates. 24. Towing pintle. 25. Taillights. (Picture from TM 5-2350-262-10.)

The operator's controls are sketched here. 1. Suspension control levers (left and right). 2. Switch panel. 3. Suspension SPRUNG/UNSPRUNG lever. 4. Gage panel. 5. Steering wheel. 6. Trailer brake control. 8. Start aid control button. 9. Winch control lever. 10. Ejector control lever. 11. Apron control lever. 12. Domelight dimmer switch. 13. Bilge pump light. 14. Bilge pump lever. 15. Transmission shift lever. 16. Warning buzzer. 17. Personnel heater. 18. Bilge pump stop lock. 19. Ejector stop lock. 20. Winch stop lock.
The start aid control button injects fuel into the engine intake to aid starting in cold weather. Though no clutch pedal was required, the transmission speeds were selected manually. (Picture from TM 5-2350-262-10.)
21. Arming firing unit. 21.1. Inclinometer. 22. Ventilation fan. 23. Hand throttle. 24. CB/GS steer selector lever. 25. Winch shift lever. 26. Hatch cover release. 27. Hand brake lever. 28. Seat vertical adjusting lever. 29. Seat horizontal adjusting lever. 30. Hydraulic oil reservoir filler and dipstick. 31. Heater control valve. 32. Accelerator pedal. 33. Brake pedal. 34. Headlight beam selector switch. 35. NBC system air heater. 36. Air purifier switch.
The arming firing unit controls the smoke grenade launcher system. The CB/GS steer selector lever switches between clutch-brake or geared steering. Clutch-brake was to be used when driving in close quarters and at low speeds. Geared steering was automatically when the transmission selector was moved into 5th or 6th gear, while clutch-brake was automatically selected when the transmission was moved into either of the reverse gears. (Picture from TM 5-2350-262-10.)
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.)
This M9 is engaged in scraping operations. The dozer blade is in the raised position, allowing dirt into the scraper bowl. This vehicle is being used by a marine to create berms during Operation Enduring Freedom. (Picture taken 6 Feb 2003 by LCPL Kevin C. Quihuis, Jr.; available from the Defense Visual Information Center.)
The scraper bowl on this machine is filled with dirt, which could increase its weight by 20,000lbs (9000kg). The vehicle's operator is PFC Shawn Janecek from C Company, 1st Combat Engineer Battalion, 1st Marine Division, and he is creating tank crossing points during Operation Enduring Freedom.
