The Caterpillar 950F wheel loader was introduced in 1990 in the USA, Japan, and Belgium as the replacement for the Caterpillar 950E. Production began in Brazil in 1994.

The 950F has a 3116 engine producing 170 flywheel horsepower (FWHP). It comes standard with a diagnostic connector, unit injection, computer monitoring system, inboard mounted final drives, enclosed/adjustment-free brakes, multi-row module radiator, ride control system, increased bucket size, and modified cab seats for operator comfort.

The 950F was manufactured in the USA, with a 7ZF serial number prefix; in Japan, with a 4DJ prefix; and in Belgium, with a 6YG prefix. The 7ZF and 6YG units have limited slip differential.

Production of 7ZF ended in 1992.

The Caterpillar 950F Series II wheel loader was introduced in 1992 in the USA. Production began in Japan and Belgium in 1993. At this time Caterpillar updated the original 950F and began producing two new units: one in the USA, with a 5SK prefix, and the other in Belgium, with an 8TK prefix.

The new 950F II units have a 3116T direct injection engine, electric shift with autoshift, lower sound levels, and a new marking system.

In 1993 and 1994, all units received full hydraulic brakes, redesigned engine access doors, and had their fuel tank capacity increased to 68 gallons (257 L). It was now available with a number of new options: ether starting aid, engine air intake heater starting aid, and air suspension seat. It also had R134A refrigerant replace CSC-based R12 in the air conditioner. All these features were implemented beginning with 5SK00743, 4DJ00816, and 8TK00816.
