A quick post because I've been slacking (blog-wise anyway) ... Here's the ATV sized "road grader" I made. It's not a real heavy duty but it works pretty good for the sand and gravel I'm using it on. I was originally going to put actuators front and back, but I realized it was more simple to have the front lift high enough that the fixed rear wheels engage. Plus, now I have an extra actuator so I can add retractable york rake or something. I have video of it action... if I can find it. The lawn mower was just to test it.
