A Pilatus PC6 will do this just nicely. Ok, agreed, not exactly a
"regularly used towplane".

Don't forget the NZ turbine cropduster offshoot being sold for
skydiving, the PAC 750XL:

Brake release to 12,000 ft takes 12 minutes with a 2 tonne load. The
plane without the skydivers (but with fuel & pilot) weighs 1400 kg, so
it can presumably climb at over 2000 fpm lightly loaded.

Ground roll at MTOW is 1244 ft, so presumably considerably less at
light weights.


Biggest problem: best rate of climb is at 95 knots, best angle is at 85
knots.
