Mowing Jd2305. 54C mower deck bolt

Wvanatti · Jul 26, 2020

My 2010 JD2305 has a 54C mower deck. One of the mower blade bolts came loose and damaged the threads. I want to make sure I order the correct one.
This is what I found “19M7872 John Deere OEM Blade Bolt M12x25”.
But the picture just doesn’t look like it’s correct.
Anyone ever had to replace one ? Any part number? I have my books, but it only shows the bolt and torque. No part number. Thanks

That sounds correct. I have a 62D deck but I think the design is similar. Mine has M12 bolts and 25mm length seems correct because they are about 1 inch long.

If I were you, I would just go to the local hardware store and pick up a M12 x 25mm bolt and try it out. After all it's just a bolt. John Deere doesn't have magic bolts.

The only variable on metric bolts is thread pitch. I would guess a M12 is 1.25 pitch, but take the old bolt in and compare to make sure.

Thanks for the input. I was just being lazy to not drive 3 miles to a store. Was going to order off line. I retapped the old one to get by with.Torqued right down.
Was just going to order a few for spare if I knew for certain the correct size.
Thanks again for the reply.
