The VG4 doesn't make as much power as its size might make you expect!!

The Wisconsin 4 (I forget the model#) is about 24 HP, enough to run
the hammer at idle but not under load. The Deutz is ca. 40 HP. The
hammer was originally run from a 15HP 400V 3PH motor. I salvaged the
motor's shaft to use as a jackshaft between diesel and hammer.
Used to run the flathead VG4D engines on a lot of swathers and
balers. Heavy slugs. Fairly torquey, but about 1800 RPM wide open.
