trenching through rocky ground

as title states.. have a job in a few days that will challenging to say the least.. commercial site that's super rocky... on inspection today it looked like a stinking quarry. smaller rocks generally. less than 4" but some up to 8" or so. would you trench this with shark teeth or just excavate this all out with a mini? 12" bucket on mine... and how many ft per day can I get out of a mini with decent operator at 12" deep you think?

if its really bad, i do the mini with a small bucket, and mostly for the main line. we have a 9" bucket that works well in tighter spots with minimal overdig. in open areas, we can probably get 500 dug and backfilled. but i usually estimate less, around 300.

My first time operating a mini I did 350' going 3' deep and it took me about 9 hours. So I would say a experience guy should easily be able to do over 1000' in a full day at 1' deep.

Regardless less of experience, production is site specific and depends on cycle time, groundforce breakout and site conditions.

Super rocky? How many feet wide and deep are the rocks?

Save yourself a lot of headache and rent a rock saw. Sprinkus and I work extremely rocky ground on a daily basis. A mini ex would just make a huge mess. Generally we just use a chain trencher with shark teeth, but we do have saw attachments for all our mini skids.

Rock saw isnt available anywhere around... the trench has shark/ cup combo chain. 70/30 I believe. I think it will do the trick.. this is a commercial site where they excavated alot of dirt/rock.. they are also bringing in 4-6" of good topsoil to cover what was already there and from there spoils of installing all the utilities. . So I shouldnt have to trench to deep in the old existing soil...I hope... lol

Just fyi, on a commercial site "4-6in of good top soil" translates to "just enough to paint the ground with it."

Which rock saw attachments are you using for your mini-skids? I have not found any and have been searching, but I have seen those for full size skid steers.
