Well, unfortunately when I first bought the mower back in March, I immediately ordered a kit online that included two new spindles, blades, and a new drive belt. I replaced them as soon as the kit arrived, but I can't remember how the other ones were and I want to be sure it's right. If it's not, I'll switch the other one over as well. The one still on the deck has the washer under the pulley, but I've been second guessing myself lately on if that's right.most likely above it, can you not look at the other one to verify?
