While the fundamental principle is identical, the 120G's system is generally simpler:
Hydraulic Control: The 120G likely uses a more traditional hydraulic control valve directly linked to the steering wheel, whereas newer models (H, M Series) often incorporate pilot hydraulic pressure or even electro-hydraulic controls for smoother operation and integration with advanced systems.
Lack of Integration: The 120G's steering is a standalone hydraulic function. Newer models integrate steering control with electronic systems for features like return-to-straight and coordination with other hydraulic functions.
This 3G-8069 steering cylinder is used for 120G 12G 130G 140G 160G motor grader.
