Engine and Powertrain
- Powered by the Cat® 3044C DIT engine, a 3.3 L, 4-cylinder, turbocharged, electronically controlled diesel engine.
- Gross power output is about 82 hp (61 kW) with net power around 76 hp (57 kW).
- The engine is paired with a hydrostatic transmission providing a smooth, responsive travel speed of approximately 11.6 km/h (7.2 mph).
- Optional 2-speed transmission available for enhanced productivity in specific applications.
- The 268B features pilot-operated hydraulic controls for precision and ease of operation.
- Right-hand joystick controls loader lift and tilt functions with minimal operator fatigue.
- Left-hand joystick manages the hydrostatic transmission allowing effortless vehicle propulsion.
- Low-effort joystick design enhances operator comfort and productivity by reducing physical strain.
- The hydraulic system incorporates a variable displacement piston pump delivering 125 L/min (33 gal/min) at a maximum operating pressure of 28,000 kPa (4060 psi) for the high flow auxiliary circuit.
- Auxiliary hydraulic circuit powers work tools such as breakers, grapples, and sweepers with consistent flow and pressure.
- Ergonomic layout includes an adjustable contoured seat and cushioned armrest.
- Control interlock system disables hydraulics and transmission when the operator leaves the seat or raises the armrest, ensuring safety.
- Excellent visibility with clear line of sight to work tools and machine sides.
- Safety features include ROPS (Roll Over Protective Structure) and FOPS (Falling Object Protective Structure).
- High-performance hydraulic pumps are engine-driven without belts, increasing reliability.
- Variable displacement pumps ensure efficient power delivery and fuel savings.
- Dual hydraulic circuits manage lifting, tilting, and auxiliary functions independently.
- Standard hydraulic pressure is 23,000 kPa for lift and tilt; 28,000 kPa for high-flow auxiliary circuits.
- Operating weight roughly 3,626 kg (7,995 lbs).
- Rated operating capacity of 1,225 kg (2,700 lbs) at 50% tipping load.
- Lift arms designed with a straight load path and spherical bearings distribute stress evenly, enhancing durability.
- Dimensions include width over tires approximately 6 ft and length with bucket near 11.87 ft.
- Pilot-Operated Controls: Hydraulic control method where small, low-pressure pilot lines control large hydraulic valves for precision and ease.
- Hydrostatic Transmission: Type of transmission using hydraulic fluid for smooth power delivery and variable speed control.
- Variable Displacement Pump: Hydraulic pump that adjusts fluid flow rate based on demand, improving fuel efficiency.
- Control Interlock System: Safety system that disables operation when operator is not properly positioned.
- Roll Over Protective Structure (ROPS): Safety cage to protect operator during rollovers.
- Falling Object Protective Structure (FOPS): Framework designed to protect the operator from falling debris.
