I have an old blade similar to yours which I inherited from my father. I have used it occasionally for almost 50 years. Walked by it in the shed the other day and it struck me that the extra holes toward the top of the blade allow for shifting the whole moldboard to either side by removing the bolts and mounting it using the offset holes. Felt brilliant for about a quarter of a second and since have felt like an idiot for not recognizing that at least 40 years ago. Pretty sure everyone else with a similar blade already knew about that feature.
My old ford blade has that feature and I have used it a couple times on the ditch along the gravel driveway. But not in a long time, I found just running the tires in that ditch a couple times a year opens up and keeps it flowing
I watched my neighbor lime his fields but for some reason he chose powdered. Same style spreader as yours. I think the lime went everywhere but on the field.
I use my blade offset during mud season when I don't want to run the tire to close to the soft edge but I want to dress the edge to let the water run off. Changing the blade over to offset looks easy but I find it to be a pain.
It's an option to have rear mouted blades. I find by going backwards you can polish the finish coat off better.
According to the label on our bags of chalk for ballfields, which is just powdered lime, it causes California in cancer. What doesn’t these days?
EA had a MUCH better (easier to use) idea for blade offset, with their "6 Way Deluxe Scrape Blade".
Mine is an imco. Ppl say it's light duty, but seems about the same as the dearborn I had. It's probably not extremely heavy duty, but sure a lot thicker than the in store brands. I'm pretty sure mine was used as an offset......new bolts and nothing is rusted up. Kind of a chore to do but still probably better than then new style.
