</font><font color="blue" class="small">( There's another outfit that does if you'd rather do the conversion with a pin-on adapter on the bucket .... but it costs more. Also - jinman has one setup like that and it sticks the bucket out there farther than I would've liked so I opted to do the weld on. It was cheaper anyway. I just don't remember that outfits name right now. )</font>
My adapter is made by Kasco and it's called a Uni-Hitch. It's a bucket plate that uses the existing pin brackets on the bucket, but I don't recommend it at all. It works as advertised, but it adds 10 inches and takes away a lot of curl power (that's digging power). I think the 16LA and 17LA adapters are all the same, but the Kasco has to be specially made by the factory because some early New Holland buckets had slightly different pin spacing. Anyhow, it was $300, so it's a lot more expensive than the weld-on plate.
I got my adapter for the loader arms from New Holland, but I didn't pay what these latest guys are paying. I remember my plate was about $370. I can't believe the cost of steel in one year has driven the cost up to $450, so I think I'd see if I could find a better price. That seems a little expensive. Mike paying $400 I understand, but $450 seems like a price they would charge for an "installed" adapter at the dealership. That's an extra $50 labor for removing the old bucket and putting the new adapter on. If you do it yourself, you should get a better deal. Are you having the dealer put your adapter on?
Good luck with your quick-attach. I think you'll love it.
BTW- One more thing. All factory quick-attach buckets are heavy duty buckets. If your bucket is a standard bucket it may not be designed for the quick-attach loads. I'm not sure of this, but I do know that all the factory buckets are heavy duty models with the plate welded on.
