[AT] more HP guaranteed!/now front end on the ground.

[charlie hill]

Yep it does that but for some reason the D-10 we had when I was a kid
would "walk" it's way out.  I want to say I've had my D-14 do the same
but I've never done enough tillage work with it to be certain what was 
happening.
It was just a brief episode when I nearly got stuck while bush hogging a 
pasture
and the tractor seemed to "walk" for a few feet until it got some traction.

I don't recall that back and forth but then I was plowing red clay. I do
remember if there was enough spinning the tractor booster would raise
the plow nearly out of the ground.
