Operating on leach field?

[DieselBound]

Wanted to follow up to my above comment. From Homeowner Manual for Septic Tanks and Leach Fields

DO NOT...

drive vehicles or place heavy objects, such as portable swimming pools, over septic tanks and leach fields. In addition,- stakes-for-plants and supports for children's s swings should not be placed over septic tanks and leach fields.

I've cleared a path through the brush so I can get the tractor to just below the leach field, which is on a sort of sloping bench. I'll be manually hauling the brush and small trees down to the tractor to chip them. At least it's down hill.
