I do use a letter series for plow, I use my C with a blade mounted where the bucket goes on the loader. It does good besides when it's angled, the blade tips to one side, but otherwise it works great because I can build the snowbanks higher... i would not reccommend it for dirt with a blade, but i supposed one could make it work... I can plow about 14+" of snow with my C, but it's a small blade, and I have 2 sets of rear weights, and chains... i think it does a very very nice job
