Equipment Overview
The Cat 279D is a compact track loader built for digging and construction work, a radial-lift model in Caterpillar’s D Series compact track loader range positioned above the 239D. It delivers 55.4 kW (74.3 hp) of gross power and a 932 kg rated operating capacity, suited to jobs needing strong digging performance and mid-lift reach with more muscle than the smaller D Series models.
Power comes from a Cat C3.3B turbocharged diesel engine meeting U.S. EPA Tier 4 Final and EU Stage IIIB emission standards, driving a suspended, steel-embedded rubber track undercarriage through a two-speed hydrostatic transmission. The radial-lift boom geometry delivers excellent digging performance and superior mid-lift reach, and a standard 86 L/min hydraulic circuit (121 L/min with optional High Flow XPS) powers Cat’s full range of work tools.
