I'm building one for my skidsteer. It will be suspended by a chain so that it will float if it hits something. However, I'm going to build it so that I can have down pressure too. Consider if the chain were 10 inches long. And if you had an 8 inch long vertical square tubing that would contact the blade mount when you lowered the arms. Raise the arms 2 inches and the vertical tube would no longer contact and the chains would suspend the blade. Drop the blade 2 inches and when the vertical arm hits you could then continue dropping the arms to put as much down pressure on the blade as you want. Hard to describe via words but maybe when I build it I can share some photos. The numbers I used were only for conveying the concept. I'll design it with more than 2 inches of float.
No, that explanation makes perfect sense. You'll only have 2" of float, or less, depending on undulation of the surface being plowed, but its better than full solid, that's for sure. :thumbsup:
Take my word for it.
You absolutely want FLOAT for general use especially at speed. Also some sort of trip be it whole blade flip or cutting edge flip back.
The only time you want a rigid or fixed blade is to bulldoze or in snow to cut back a hard packed accumulation and then you will need to go really slow or risk damage.
