I have 2 NOS Brinly SS-500 spike harrows for sale, still in the original boxes. These can be used with a sleeve hitch or towed off the drawbar of any tractor. The boxes are a bit ratty and there is probably some minor surface rust on the frames. The one in the pictures was in the worst box of the four I got, but I assume the others are in similar condition. The long carriage bolt in the center is to hold a concrete block or other weight on there. The piece I am holding in the last picture gets bolted on there if you are going to pull it from the drawbar of your tractor instead of using a sleeve hitch. The one in the pictures is the one I am keeping, one other is already spoken for, so 2 are still for sale. It says cultivator on the side of the boxes, but says drag harrow on the end of them. I am asking $150 Canadian each.
