Well, that's only rated capability in 2nd gear. At least to my mind
"dragging it backwards" implies a little more than beating it's rated pull
in 2nd gear ... and it's sure not something I'd want to have happen on my
lawn ! I've mowed a lawn with a 120hp row crop, but that doesn't make it a
lawnmower.

Can't comment on whether they added weights, but note that adding weights do
_not_ increase drawbar horsepower, only traction and hence (perhaps)
tractive effort. If it could deliver 8.75 hp in 1st gear with weights, it
likely could do it in 2nd or 3rd without weights.
Also, test H deliberately only loaded the tractor to it's rated load, it has
nothing to do with maximum power available.

Yup, and usually a lot more gear selections to cover the range. But I
thought we were talking $2000 tractors here, not serious tractors <g>
