Ingersoll-Case 446 Mower, Lawn and Garden Tractor Category

Original Model: Onan 16hp

The Onan engines with a 1-1/8" shaft are no longer available.

Additional Info
You will have to pull the rod that currently hinges the hood at the front and install our adapter plate to this. Our adapter plate will raise the height of the hood by 2-1/2" in the front so it helps to clear the valve covers.

If we know of any required changes, we will list those, however, some adapting during installation should be expected.
