    everybody here says the main is fine but i should raise the lats to 6-8".

    after all the plumbing i have done in pools and such, i'd rather have them deeper.

    swing pipe is cheap.

    I get my pipe in at least 8" deep. But my girlfriend would probably say its less than that.

    We pull pretty much everything unless it is extremely rocky and new construction before the sod is laid or Hydrosprayed. The normal practice we do on existing lawns is to lift up the sod in a square where all heads and connections will be. We then dig the holes with a one man auger, on harder ground we use the auger on the dingo. We then simply pull all of the pipe from hole to hole with no problems. The only digging we have to do is for the valve boxes, if the ground is hard we break it up with the dingo auger. Once all connections are made we simply back fill the holes dug for the heads, connections, and boxes. Drive the dingo over the slight mound formed from pulling and place the lifted pieces of sod back down around the heads. Once we are done there is very little evidence we were there, usually the most evidence visible is some dirt that might be near the top of the grass where we had to dig for the heads. We do so little digging that a 3 man crew could probably go to an install with only one trench shovel and one spade and not be slowed down at all.

    Nobody marks out a system before they aerate, in my experience. It's always feigned astonishment that heads were broken or pipes got pierced. :rolleyes:

    The only reason I could see if you used it for more than pulling pipe.

    I used a buddy's 410 a few times before I had my dingo. If I could double my install biz I would get one for my self. In the meantime the versatility of the Dingo being able to be moved around from irrigation to masonry work to prepping small lawns to doing landscape installs in tight areas is to important.

    i agree, 10" is about right...i shoot for 12 and usually end up with 10...besides, don't you want to be at the depth of your valve boxes?...and do you mean 10" is fine for one pipe only? or do you mean you never put two pipes in the same trench period?

    aeration is definitely something to keep in mind...the deepest is usually 4", but i don't know why anyone would put a system in that shallow...we are 8" in some places on our current install but that's as shallow as it gets...

    I work on a lot of soil that needs no aerating, so it is an eternal surprise when some gullible homeowner has aeration done, improving the soil not at all.
