The AR 400 heavy duty wear bar for my JD 54 inch plow was delivered fast. This is the 2nd wear bar I have purchased from Heavy Hitch. My first AR400 bar has worked far better than the JD bars I have purchased. I plow about a 1/4 mile of my subdivision so I put my plow to the test. This wear bar is worth the cost because I would need at least 3-4 JD wear bars to match the durability of the AR400 Heavy Hitch product. I would highly recommend this wear bar!
