Cidertom,
It turns out that Amerequip made the WHOLE 448 hoe for Deere.
So, I measured a 448 Deere bucket at the local AWE_THEN_TICK Deere dealer yesterday; check, pin diameter, length, spacing matches - then I priced it.
OUCH ! It will be a while before I shop there for parts.
Montana is another one and for me that dealer seems to be the best combination of 'close to home' and "non-premium price".
BTW, Branson is another one.
