JUGS Sports Combo (2 wheel) Pitching Machine - Manual (Page 26)

fastpitch Softball
PItch balls for softball in generally the same manner as baseball, as described
on previous pages. For risers, position wheels vertically, with one wheel on top
of the other, and set dials the same as fastball settings for baseball.
Slowpitch Softball
Reduce speed accordingly on both dials, always maintaining the minimum
35-digit differential.
Loosen the large hand screw on top of the handle and tilt machine trajectory
upward until you achieve the desired arc on the pitch and tighten hand screw.
Tennis balls
Start with a 60-60 setting for straight balls and 50-70 for curves. (Regular
baseball settings are too much for the tennis balls.)
Table 1 [right] is a detailed chart which depicts approximately how fast, in
miles per hour, a JUGS Curveball or JUGS Combination pitching machine is
throwing, when the dials are set in various positions.
The speeds listed, in miles per hour, are the average speeds of five throws at
each of the respective dial settings.
The “speed-to-dial settings” ratio will vary somewhat, depending on the air
pressure in the tires, the type of ball used, and the way in which the ball is fed
into the pitching machine. This chart will give you a fairly close approximation
of the ball speed.
