Irrigation trencher

[Gadgeteer]

Finally got around to installing a second pipe. Had to modify/improve the attachment of the bullet nosed puller to the rear of the knife. First two broke, due to movement and stress. Won't break, again. Added quick attaching wheels to one end of the sled, and a handle to the other end, so I can, easily, scoot it around the yard. Pipe ends up laying at about 8" below grade. Very little evidence of the remaining trench.

Thanks for sharing David. It is a neat tool, and looks like a nice ride.

Gadget, I'm sure your winter frost level is deeper than 8", so will you have to blow the lines out before cold weather set in to avoid busting the line?

I installed additional water lines at the approximate depth a few decades ago, and air them out when freezing temps hit. Never had a problem with freezing. I'll attach an above-ground spigot at the junction of the pipes for connecting the air line. Plus, that will allow me to hook into city water, if there are any problems with the creek pump.

Photos of trencher sled, knife & bullet, bullet puller. I guessed that the tapered nut that locks a bicycle handlebar to the down tube might work to secure the poly pipe end to the bullet, and, so far, it has worked, as predicted.

Gee it must be nice to live where there is that much "real" dirt to grow things in. :-) In PA where I lived for the first 50+ years there was shale right below a couple of inches and here in Abq there is maybe 4 or 5 inches above the Caliche in the back yard.

A couple decades ago, I attempted to hand dig a well about 6' from the edge of the creek that flows along the back of our lot. Got down to 25', and never did find water. Pulled clay all the way, mixed with very few thumbnail sized rocks.
