In 1977, Volvo presented the 4300 wheel loader - the first in the new generation wheel loaders. It was fitted with a brand new, parallel linkage lift arm system in black (to avoid light reflexes).
The parallel linkage arm system featured high breakout moment in the top position while retaining power in all other positions combined with extremely good parallel movement. The disign of the arm system also afforded the operator excellent forward visibility. Today, some 20 manufacturers have copied this new improved system. An acknowledgement as good as any for Volvo as a pioneer. Another feature on the 4300 was the pressurized, ROPS-approved, cab with integrated air condition as option. Easily read instruments and controls within easy reach provided the operator with a good and effective place to work.
In 1981 a patented gearshifting system was introduced that was both engine speed and travel speed dependent – Volvo BM Automatic Power Shift (APS).
In the same year a new load-sensing hydrostatic steering system also was introduced.
The machine was upgraded during it's time of production. At the time of discontinuation, the 4300 had been produced with 3 different engines and 2 different axle-combinations.
