Mike, thank you very much! This is very helpful information.
1: what tractors was this built for? My daughter has a 68 Commando 8 with a slot hitch.
2: roughly what year? ( is the 96 in your post a model designation or ?)
Thanks again! -Alan
EDIT: 2 yrs later another turned up very similar in THIS thread.
So did your daughter end up using the plow in the Commando 8?
And did you figure out what the odd bar was?
Or do you reckon seeing mine that this was some sort of PO add-on?
