This chapter provides a general description and
identification of the M9 ACE (fig 2l), as well as
tabulated transportability characteristics that are
necessary in movement of the item.
a. General. The M9 ACE tractor is a full-tracked
(hard rubber), armored amphibious, multipurpose
combat engineer vehicle capable of performing tilt
and straight dozing, scraping, rough grading, and
hauling. The tractor features a front-loaded
operated apron, and positive-load ejector. Dozing
and scraping are accomplished by raising and
lowering the entire front of the vehicle by means
of the hydropneumatic suspension system. This
dozer/scraper tractor is powered by a 295-
horsepower diesel engine. The M9 ACE has six
forward and two reverse gears and is operated
only by the driver.
