<font color=blue>So...how much do we owe you if we use the exact same design but only SLIGHTLY different ????</font color=blue>
All power trac owners on TBN get royalties from everything that I and anyone else think of in the form of invaluable fun /w3tcompact/icons/tongue.gif
As for the cable/flex pipe layer, I might go back and look for a longer plow share, since this one cuts in so nicely, I think it will handle it with no problem. Multiple passes at greater depths is no problem with the unit out in front. I tried it and went over the same slice three times with no problem. Very accurate. I measured and this on will get it down 10 inches. The only reason I bought this particular plow share was because it was the cheapest /w3tcompact/icons/laugh.gif. They had others all the way up to $15.00 /w3tcompact/icons/shocked.gif (hey, I'm frugal). I'll take a one to two inch diameter pipe and bend it in a 90 degree bend, not too tight, and put some bracing on it. Then I'll attach it with bolts, so that it is removable. I should be able to feed the cable down the pipe as I go if I make a reel stand and attach it to the top of that angle iron that I left sticking up for automatic feed.
As for operation, I first tried it with the edge slanting back from top to bottom, thinking that it would slice down into the ground. It tended to bunch the sod up a little, but not much. I then changed the angle with the joystick so that the bottom of the edge was out in front of the top by about an inch and it worked even better, with hardly any sod tear.
When I finally decide to make the cable layer, I think I'll make one pass with just the blade, then go back and lay the cable. That way, I'll have less resistance and I will solve any troubles that might pop up if I run into roots or rocks before I have a spool of cable or pipe to deal with.
As soon as I get a chance, I'll video tape it in slicing mode and post it to my website. Probably in the next week or two.
Oh, yeah, one more thing. After I made multiple slices in my back yard, I just drove the PT over the slices and that pushed them right back together, leaving a small line of dirt that could easily be washed away with a hose or the next rain. That was nice.
