EQUIPMENT CHARACTERISTICS, CAPABILITIES, AND FEATURES
The Backhoe Loader (BHL) is a pneumatic tired, diesel engine driven, Two-Wheel Drive/Four-Wheel Drive
(2WD/4WD) Front End Loader (FEL)/backhoe used for excavation of small emplacements, material handling, and
general construction tasks. The BHL offers the mobility and operational characteristics demanded by modern
armed forces. Operational characteristics include the ability to operate at all possible humidity levels, at ambient
temperature levels from 25F to +120F (32C to +49C), and at altitudes up to 10,000 feet (3,048m).
The BHL consists of a hydraulic FEL bucket and hydraulic backhoe bucket controlled from a Rollover Protective
Structure/Falling Object Protective Structure (ROPS/FOPS) cab, which contains all operator controls. The BHL is
powered by a 4.5 liter turbocharged diesel engine that operates using DF-1, DF-2, JP-5, and JP-8 fuel. The
engine meets U.S. Environmental Protection Agency (USEPA) Tier II requirements. Power is transferred to the
wheels by an automatic transmission. Stabilizers are used to stabilize the BHL when operating the backhoe.
