I've got a plow on one of the first AGS 2160 models. (I think is 42") The plow is basically for snow because the tractor can't push much. After some modifications to the tractor (filled the tires, added concrete, tire chain's) it will move some dirt. Then we added a hinge to disable the spring loaded blade trip. Now I can fill the blade about 1/2 full of sand. Its still not a real tractor but with some help the blade will move a little dirt if its loose.
I've made a number "modifications" to my cub it seems to be a pretty soild little machine. I have plenty of pictures if you are intrested.
