Broken 18" disc on disc harrow

[bradlyallen1]

Broke a disc today. It is an 18" notched concave disc. Went to agrisupply.com and I see about 10 choices with differing measurments. How do I figure out what I have so I can correctly replace it? Thanks.

Take the gang apart and measure the size of the arbor bolt hole and disc thickness at the hole. Make note of the shape of the arbor bolt hole in the disc. Order a suitable replacement, factoring in any wear on your old discs.

Can't you take off even a good disc on side your going to replace and have to take off anyway and match up?Measure disc across making sure it is an 18"er.Measure distance between notches. Also make sure inner center holes or squares are same.
Also don't know if it matters to you,but some disc are made in India,Brazil,Canada ,etc.
Here's a pic of my A@B Eagleline DH my disc are made in Canada.

I may stand corrected ... I believe the shaft can be 1" or 1 and 1/8 th inch or an inch and a quarter ... as long as the disc is the 18" and center hole matches the shaft, should be good.
