Hi Steve abd Dan..
Glad you like the photos..I did get the ripper teeth done today and mounted on the drawbar...Another day, another dollar...
I am posting a link to one of my U-Tube videos featuring an oval track D9..It starts with an old D8 and toward the end the D9 gets a chance...The D9 has to be redone as the dozer operates too slowly..
