      It’s a very simple setup; a length of 1/4 wire rope with an eye swaged at both ends (sorry, do not have the measurement), a 2′ Harbor Freight sheave, two 1/4″ forged shackles, one 1/4″ long shank forged eyebolt (for adjustment). I’m still hunting for the diagram, but I fear it’s lost.

        Those belt drives were also used, I believe, on the early Toro Dingo, Bobcat, and Boxer walk-behind skid steers.

          I don’t understand when you say parts are unavailable. You can get them at Walmart. I had a CVT “Varimatic Drive” in my ’49 Cushman scooter.

          Simple search turned up this: https://www.google.com/search?client=firefox-b-1-d&q=varimatic+belt+drive

            I found my file pictures if you’re interested, Thomas.

              Here is the general idea. This was made up for a member that had the pendulum pedals so some of it doesn’t apply, just the blue lines. I’ll keep hunting for the mod that I did on my own dozer.

                I thought about linear actuators but deemed they would be too slow acting in this application, so I engineered a simple cable and pulley system that has better sequencing and works very well, and has the feel of power assist. And now I can’t find the file. I’ll keep looking.

                  Your driveway looks like hard packed snow. How many inches did you get, or are you measuring it in feet? How is the house coming along, or has the weather brought things to a halt?

                    Whoa! Is that normal for winter there? Looks like you need a snow blower attachment.

                      I have seen in other posts where the same issue of blowing oil was remedied by just running a clear hose up the ROPS support. Stuff some bronze wool in the end to keep the bugs out.

                        Could you slap a couple of these on your hydraulic reservoir? We have used the 120 volt versions on the outboard motors of our rescue boats and they work great.
