When I am digging a trench with my Kioti DK50, I often encounter rocks in the trench. I soon grow tired of digging the side wall out to uncover the rock. There are several products out there you guys and gals should be aware of:
Dexpan- expansion agent- drill 2" hole, mix up and pour in and wait overnight for it to split the rock
ATF Approved small scale blasting systems- currently there are only 2 ATF approved blasting systems on the market which are legal in the US. One is the Microblaster (MB) and the other is the Sierra Blaster (SB). I have used both extensively and since I am too impatient to wait for the expansion agent to work, I chose to use these systems. Both work very well, but the MB is better suited for smaller rocks due to a smaller charge (5/16" Dia hole) and a limit of only 3 simultaneous blasts. The SB is a bigger charge (3/8" dia hole), is waterproof and can detonate 10 simultaneous blasts.
The word "blasts" is misleading. When they go off, it sounds like a .22 rifle shot. There is no fly rock and no big concussion. For extra safety, I cover the charges with a painter's tarp and when it goes off it sounds like "poof". Literally.
The caveat to the two blasting systems is they don't work if the rock is buried- there needs to be some place for the rock to move or it won't work. The charge isn't large enough to move dirt too.
If you encounter rocks where you are working, I'd recommend looking up some Youtube videos to see the comparisons of all three. There is one I prefer over the others, but I am not here to make a sales pitch. See for yourself which one would work for you. These devices could save a lot of wear and tear on your tractors and actually make dealing with rocks a lot of fun. I think so, and I don't have a powder license and have used my system for years of trouble free service. One of the systems
is being actively utilized by miners all around the country.
