I removed an above-ground pool, and I want to remove the sand/rocks and add contained by some loam. A bobcat would make this much easier, but it might involve driving over my septic system. Is this a really bleak idea?
Answers:    If the bobcat is wispy enough and the septic container is sturdy enough, you might know how to get away beside it, maybe. But consider the consequences of a less-than-ideal scenario.

I wouldn't recommend it. The results aren't pretty.
You shouldn't drive anything beefy over a drainfield. I don't know how much a bobcat weighs, but the providence of crushing the drainpipes in the paddock is real.
