Ditch Witch Earth Saw

Has anyone used one of these attachments on a mini skid? Our chain trenchers seem to be taking too much of a beating, and it looks like one of these might be the answer.

i used a contraption similar to that when i was plumbing pools, it excavated 12" wide at the bottom 24" wide at the top and 18" deep, the spoils went to both sides. good thing since it displaced 2.25 cf-per linear ft the fellow that designed and built the machine folded up and i don't know where it is now. you better have your locating cap screwed down tight before turning that thing on.

Offhand, I think the mini-skid earth saw is too light. If you have to go that route, you probably need at least a couple of tons of machinery to deal with rock.

Ditch Witch is pretty good in our area, so I am going to have them bring it out to a jobsite next week and give it a spin.

From what I hear, the local guys says it is pretty good as long as it is not wet. If it is wet the chain trenhers work best.

We generally trench about 8" deep, and around 4 in wide. There is no frost line here so we dont have to worry about that.

The saw should do 12" at 3" wide. I would probably have to trench about
10in deep because the pipes would be stacked more in a 3in wide trench.

stacking pipe in any situation will bring you heartache if you repair or ammend a system, stacking is common in the pool biz and a PIA doing leak repairs
