$270 shipped ebay

 

I'm in the same boat. I've got a lovely HS621 in need of a new auger. The price on the Honda is ridiculous and after taking off the broken auger and having a look at the welds I'm not impressed with the quality. Has anyone ever tried to retrofit a Toro auger onto an HS621 or HS521 ? The auger new is $100 cheaper and new paddles down the road would be easier to find and well under half the price. Am I talking blasphemy here. I've got a welder and a lathe. Even if I were to buy a new Honda auger I would definitely be redoing some of the factory welds before I install it .

 

As others have mentioned, you can get the HS621 Auger Assembly on Ebay new for $270 shipped. There is also a used HS621 assembly currently on Ebay for $149. Doesn't look too bad, but still pretty expensive for a used auger.

The HS521 and HS621 both use the same auger assembly which doesn't really help with the cost issue. Might be able to find a junked 521 or 621 on Craigslist and salvage the auger. Good Luck!

 

I am also looking for an auger as well, I would love it if a Toro auger would work, you can get long life paddles for Toro augers.

 

I'm looking into it to see if this is possible. Of course some precision cutting and welding might be in order but initial measurements don't look that far off. I need to get my hands on the right Toro auger. Might be time for a build thread over in the Honda specific forum.
