Equipment Overview
The Cat 259D is a compact track loader built for material handling and truck loading work, a vertical-lift model in Caterpillar’s D Series compact track loader range positioned above the 249D. It delivers 55.4 kW (74.3 hp) of gross power and a 921 kg rated operating capacity, suited to jobs needing extended reach and lift height 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 vertical-lift boom geometry gives extended reach and lift height for quick truck loading, and a standard 76 L/min hydraulic circuit (112 L/min with optional High Flow) powers Cat’s full range of work tools.
