B4681 subframe on a B7610???

[Danc]

Ok here is another dumb question....I'm good with those... /forums/images/graemlins/blush.gif

I've heard people saying that they have a B4681 subframe on a B7610.

Since the Hoe that goes on this tractor is a 3 point.

What does this subframe is used for? and are there any pictures somewhere available?


Thanks.
