Help me pick a box blade

[dex3361]

The dealer has a 6' Land pride that is $650 heavy duty. I was reading my OM and it says I should have 65" maximum width on the box blade.

So now I am back to everything attachments and looking at the 66" box blade. Should I worry about the extra inch and drop down to 5'? Seems small for my tractor (L4400).

Thanks guys.

I have been using a 7 foot BB on my L4400HST and it does a great job. If I were going to buy a new one I would get a 6 foot though because it just covers the wheel width. I hang the 7 foot BB on trees in the woods other than that it handles it just fine.
