Since I got the frame of the blade unit fabricated and the hydraulic system up and running, I just had to take it for another test spin before resuming work on the plastics for the blade. After that bit of fun, and additional motivator, it was time to get down to work. I had bought a sheet of ¼” polyethylene plastic which would become the curved portion of the blade, and a 3/8” thick bar of polyethylene plastic for the cutting edge. Why polyethylene? A look at the material properties of it and it stays flexible at low temperatures, it’s durable, and best of all, it’s slippery, meaning snow will slide right off of it. I chose this material for the wear bar so that the asphalt would not get torn up. The downside is that it doesn’t have the cutting power to shave ice off, but I wanted to get the snow off the asphalt before it became ice. Also, it’s a lot easier on the grass with a plastic cutting edge versus a steel cutting edge. After some drilling of holes, and a lot of clamps, I soon had the blade much closer to completion. Note that there’s some springs on the blade for the trip release that need to be assembled, instead, ratchet straps make for a quick substitute.
Then it was time to fasten the blade back onto the unit and prepare for a test run
Notice that the blade is being operated via the hydraulics, but I have to reach down to the valve body and operate them with my hands. This will be addressed soon as it will get foot pedals to control up/down and tilt left/right.
