The springs are the key to absorb shock and take the stress off of the loader. You should be traveling at low speeds regardless and have time to react to the blade tripping and just stop asap. My Dad & I had put an old 6' truck blade that was modified to be 8' wide and 6" taller on his Farmall M. When it tripped many times it would flip all the way flat, so I put a cable on it to limit the travel to about 3/4 which was enough to give but still push. Keep in mind this is on driveways etc that we know have no solid obstacles. Wheel weights, tire chains, and this plow made the M a snow plowing beast. The only drawback was it was almost too big and heavy. I put a plow on my ATV when I bought it which worked pretty well for several years until I bought my little tractor, which is what I use now. I have seriously considered rigging up my 5' ATV plow on the tractor loader. I would just have to add brackets and pin locations for the SSQA. Looking at stuff in here really has me thinking about it now. Might have to look at it again and figure something out. I would however only plow with the blade straight to help eliminate added lateral stress on the loader.
