International Harvester 260A: American backhoe loader with a D-239 four-cylinder engine and torque converter for earthworks and utility trenching
International Harvester was an American manufacturer of agricultural machinery, trucks and construction equipment whose business was split in 1985 into the Navistar commercial vehicle brand and the Case IH farm machinery brand. The 260A backhoe loader belonged to the company's construction equipment line and, as usual in this class, combined a front loader bucket with a rear excavator arm on a wheeled chassis.

The 260A is powered by a four-cylinder, 3.9-litre diesel engine, type D-239, built in-house by International Harvester, producing 55.2 kW (75 hp) at 2,400 rpm. Power runs through a torque converter with six forward and three reverse gears. Wheelbase is 2,042 mm, the hydraulic tank holds 70 litres, the cooling system 13.2 litres and the fuel tank 75.7 litres.
Backhoe loaders of this type combine a front loader with a rear excavator arm on a single road-legal chassis, and through the 1970s and 1980s saved contractors from buying two separate machines. Four-wheel steering and an oscillating front axle were typical equipment for the class, allowing a tight turning circle on road works while keeping good wheel contact on uneven ground. Machines like this were mainly used in utility, drainage and municipal work.
When buying a used backhoe loader with a torque converter, the condition of the converter fluid and cooling system is decisive, since overheating damages the clutch packs inside the converter. The D-239 engine is regarded as durable, but the head gasket and cooling system should be checked for leaks. Corrosion at the excavator arm pivot points and play in the front-axle steering cylinders are common weak points on machines of this age, as is the availability of spares for the older drivetrain.
