Here's mine a Mahindra 2615 chains front and rear. Mostly I use the rear blade that I modified by attaching an old section of water pipe, welding it to the skid shoes and attaching the little brackets to give it more support in the middle.
I used to use it on my old Ford 2n and did a pretty nice job of bending it at which point I bolted on the iron channel which I later welded. I then snapped the thing at the point were the blade pivots and had it rewelded and strengthened. The guy that did it welded it back with a slight twist and I had to cut out part of the blade to get it to spin again, I won't be using him again.
I live in the cascade mountains in northern California and we tend to get really wet snow. Every winter is different but when it snows we tend to get at least a 8" and usually more.
