Gear Driven Hydraulic Scarifier System on Boxblade

[3RRL]

Hi Scott,
I chose 4" of travel, figuring that would be plenty of dig depth when the boxblade is level. When tilted forward all the way, it looks more like 6" to 8"? (Not sure exactly.)
I could have used a longer stroke for the system but figured this would be good...and it is. I don't think the tractor would pull much more when they (all 7) are burried all the way in hard ground. The shanks I bought at Agri-Supply are now in the middle top hole, so I could set them one or two holes down more, but as it turned out, I don't need to. That means I can now by the shorter ones for $10 ea. if I need to replace these.

This is another video of it "working". It's a little shorter. It shows a ledge I had to cut down after grading a pad below it. I needed to "cut" the sharp drop-off so it wouldn't collapse when raining. I wanted to "round" it off rather than than just an angled slope.

If you look closely, you can see the rippers being lowered down before I lower the boxblade. This will start to rip the soil loose. I also have the boxblade fairly level because I want to drag all that dirt away at the same time. Look closely when when I retract the rippers so now the boxblade rides over the crown. The ripper shanks are only used to cut the area I want...basically impossible to do with manually adjustable rippers....that is to "cut, round off, and drag" at the same time with out cutting or ripping any more than I want. Shaping in this way is a new added dimension to the boxblade use.

When I got to the hard decomposed granite, they really showed their salt and made mince meat out of it too. My 55 hp Kama really came through pulling tons of dirt. Notice how quickly the box fills with this method. Boxblade Working
