Structure
Engineered for maximum production and service life
Mainframe Strength
The D9T mainframe is built to absorb high impact shock loads and twisting forces.
Frame Rails
Full box section, designed to keep components rigidly aligned.
Heavy Steel Castings
Adds strength to the main case, equalizer bar saddle, front cross member and tag-link trunnion.
Top and Bottom Rails
Continuous rolled sections, with no machining or welding, to provide superior mainframe durability.
Pivot Shaft
The D9T pivot shaft runs through the mainframe and connects to the roller frames, allowing
independent oscillation. The full-length pivot shaft distributes impact loads throughout the case,
reducing the bending stress on the case.
Tag-Link
The Tag-Link brings the blade closer to the machine for more precise dozing and load control.
The Tag-Link design provides solid lateral stability and better cylinder positions for constant break out
force, independent of blade height.
Main Case
Elevates the final drives well above the ground level work area to protect them from impact loads,
abrasion and contamination.
