I unloaded the Grader today and put it in the shop where it is now drip drying. Sorry the rain didn't allow me to take any pictures to post.
While in the shop I did a little more investigating on the machine and I'll post my findings.
-------------Its a 1948 Oliver 70 serial# 261128G this would be the last year they made 70's (if memory serves me well)
The Grader attachment is made by Henke Manufacturing Co. out of Janesville, Iowa. I found a website for them and they are still in business in Kansas building snow plows.
http://www.henkemfg.com/henke_history.htmlThe hydralics are by Hydreco out of Cleveland Ohio and they to are still in business. Based now in Charlotte, NC.
http://www.hydreco.com/index.htmWhile studying the Grader I discovered on the right side frame rail "USA" was welded into it upside down. Then a few inches over towards the front, In a sort of fancy fashion "S SIONI 77" was welded into it< right side up. I figure S. Sioni is probably the fella who put it together and 77 was his employee number. Probably USA was welded into it while still on the ground. It would be neat to know the whole story behind it.
I think I'm going to try and contact the 2 companies still in business and see if they have any info. on this machine or even info. on their company during that time and their "partnership" with Oliver.
