The Big Scrape! Bobcat Skid loader..building campsite areas..and finishing up the new gravel road!

What happens here

To create a crowned road – a surface that is higher in the middle to allow water to run off to the sides – the box blade needs adjustment. The presenter demonstrates pulling pins to rotate the blade slightly (one notch over), creating an angled cutting edge. The blade is also dropped just enough (approximately an inch) to lightly scrape the surface. The tractor then drives down the road, with the angled blade pulling gravel from the edges towards the center. This action builds up the middle of the road, forming the desired crown and preventing water from pooling or creating gullies.

Goal: The box blade on the tractor is adjusted to a slight angle and a shallow depth to pull gravel from the edges towards the center, creating a 'crowned' road surface that sheds water effectively.

this direction and drop it ever so slightly maybe this much okay it's already set up like this and the adjuster is on this right-hand side of the track so what we'll do is we'll pull these pins out sometimes they come easy and sometimes they don't force basically take those pins out and rotate our blade ever so slightly just one notch over so what we're going to do since it's one notch over now and our blade is crooked it's gonna pull that gravel that's tipped over the edge back into the center and cause that driveway to have the crown now later on after we've driven on this quite a few times it'll develop a SAG where the tires go it's okay we'll come back over it and we'll drag it first like this we'll pull it all to the center and then we'll knock it down and then basically over the years we'll basically pull the gravel from the edge into the center and then drag it back flat pull it from the edge into the center and then drag it back flat now you can do too much of this and it can tear up your driveway okay so you can continue to dig and dig and dig and basically what's going to happen is you're going to end up down in the dirt we don't want to do that we want to maintain it properly basically every
