Tablerock Ranch eastern Wa | When i called JBS to ask what size rocks were safe he answered-----hey i didnt sell you a rock crusher ! We did some light damage to ours when we used a 4" screen to screen our manure, we then went to a 2" screen and i am happy with it. What we paid for the spreader i wouldn't consider running rocks through it ----- know one makes a vertical spreader that will stand up to big rocks ! |
