Recycler attachment debacle

[bizzo15 52]

Hey guys I need some assistance from you knowledgeable folks.  When I bought my 312-8 last year the previous owner gave me a recycler attachment for the 42" rear discharge deck.  I never got around to installing it last year but midway through the mowing season this year I decided I was sick of dealing with grass clippings and wanted to setup the recycler attachment on the deck.  I ordered some new mulching blades and decided to tackle the job the other day.  Attaching the recycler to the deck was real easy.  I also had good luck removing the old blades from the spindles.  I ran into some trouble after I installed the new blades though.  One of the blades was hitting on the recycler baffles.  I went to take the affected blade off and rounded the nut holding it on.  I eventually got it off and after a careful examination  the spindle that  this blade goes on is missing the nut that goes under the blade.  I went to both Lowe's and tractor supply and couldn't find this nut or the nut I rounded off.  Do you guys know what the specs are on the lower nut that sits under the blade as well as the low profile nut that sits on top of the blade?  I figure I'm going to have to order them online since I can't seem to source them locally.  I'd like to get the deck back on the tractor before the next time I have to mow since this snafu forced me to mow my half acre yard with a push mower which wasn't nearly as much fun as using the wheel horse.

 

 

THANKS A BUNCH

My local dealer would probably have that in stock. Or go to partstree.com and enter your deck model #. Spindles for all 42" & 48" WH decks use the same parts.

Thanks for the link. I'll order from there as a last resort I was hoping to get the size and thread pitch of the nuts so I could source them from somewhere much cheaper. Looks like I could get everything I need from parts tree for around $12 before shipping but I bet if I ordered from a fastner company it would be like $3.
