Yes, you can put pressure on the FEL and force a deeper digging. The way my luck goes, ( you have to remember the vast majority of these perc tests are for replacement systems) as people can't pass title V tests. With my luck, putting the FEL down pressure or digging holes to back into, I then ruin Mrs. Murphy's prize winning tulip patch. Again, the majority of these are on properties that are senior in growth, trees, flower gardens, inground pools, etc.. Rare to get new construction percs, which then it wouldn't matter. These people are cutting it so close and in some instances have to wait for board of appeals and health dep't to allow another system. Supposedly, the Pilgrims landed here first and therefore, there isn't much open space that is buildable. Not like out your way. THe other thing is, I tried the 9000 groundbreaker hanging on a TC 40 or 45 and still do not like the looks or feel of the Woods. As far as the JD 710 X, working with fourth 710 and must be near 10,000 hours by now in last 20 yrs. I like the 710 other than newest style which lost some lifting power due to placement of pistons. We had for one year, a farm outside of Ironton Ohio. Came back to Massachusetts and recently moves 100 feet over Mass line and into northern CT.
