I was given the disc harrow in the picture. It's got 11" discs on 3/4" round holes. The right front disc is broken away except for its center. The only 11" discs I've been able to find are from Brinly replacement parts and they don't specify the center hole. There is enough room under the chassis for 12" discs and they can be had for not painful money.
The primary use of the disc will be to rip up sod. My lawn is 35-60 years old and I'd like to level it out some. The disc as is did an adequate job on the part I did this fall, but I would be happier if it cut deeper and chopped more.
I've read that notched discs do a better job on sod. I'm toying with replacing the full set with notched 12" discs.
Any thoughts on whether that is advisable? Should I go solid on the rear gang or notched there too?
