Spent most of the day today clearing and leveling a site for a new tractor shed/pole barn.
D170 loader (standard bucket) on 4044m tractor
BB2072 Frontier Box Blade
Here's the site (and my 5 ton) before I got started:
The first thing I did was use the root grapple to break up the top layer of soil. We've not had any rain here in my part of NC in nearly a month so this top layer is extremely hard and compacted.
After that, I leveled the box blade with the tractor perpendicular to the slope. This means that even though the tractor is on a slope (side hill) the BB will still cut level. I put the rippers in the lowest position and made passes until I established a baseline level.
I verified that the deck was level by placing a level on the bucket of the tractor. After confirming this, I re-leveled the box blade to the tractor. Then I started cutting for the proper depth for the whole building floor. A few things to note here. When using the box blade for this, make sure you start and finish well before and after your desired area. The reason for this is that the BB takes about 6-8' before it reaches full digging depth. Also, after a few passes when you start to run over your pile, you'll begin to pick the blade up earlier. If you don't leave enough room for lead-in/out your site will look like a bowl with high spots at each end. You can square this away with the bucket, but it's best to do it with the BB if you have room. Also, you'll need to haul your dirt away after a few passes so you can see what you're doing. A 6' box blade can move a LOT of dirt in a single pass.
Here's the site completed. It's hard to tell in this picture just how much dirt I moved, but I would estimate at least 2' deep on the high side.
