Today I broke the tip off of a share on my JD 4-16 F620 plow. I happened to have a good spare, but after replacing it, I noticed it was a JD A51501 "narrow cut". I had always used JD A51500 "full cut" shares.
My question is: when would you use "narrow cut" shares and when would you use "full cut" shares. Must be some reason JD sells both kinds. I didn't notice any difference in plowing with the one narrow cut share on my plow. Thanks. Al
