i usually dig 4-4.5 ft with BX24, but i have dug down to 9 ft with BX. Now I can see the expression you guys are making right now ... :laughing: how can a BX that has boom limit of 4 ftish dig 12 ft? well -- thinking outside the box, i ran into this dilemma once. I was diging to the BX max and realized uh - oh i need to go deeper. MUCH deeper for a sewer line collapse. Since the trench was already dug, I just turned the tractor around and dug with the FEL until I was down 5 feet. It was alot of driving down a steep slope, backing out of trench with fully loaded bucket. good thing the trench was already dug in middle so that helps to break the soil easier. When I was down to desired depth with FEL, I just dug a side terrance for a place for dirt for BH can reach. Then i BH'ed the rest of depth needed. needless to say - i needed a bigger machine, but i got the job done with what i had that day.
