No but you can figure it out easy enough. I'm basing this answer on an IH conditioner which has the pto into a gearbox the output of which goes out at a right angle on a shaft to a drive gear. That gear drives a chain that rolls a larger upper roller and a smaller crimper roller below. I assume you are looking for a gear for the lower roller. Otherwise disregard this response.
Take a ruler and measure the diameter of both the upper and lower rollers. Measure the number of teeth on the upper roller.
Upper roller diameter 10"
Lower roller diameter 8"
Upper roller gear teeth 20
Ratio of lower to upper is 0.8:1 (lower roller has to roll 1 1/4 revs to equal one rev of the top roller).
So 20 x .8 = 16 teeth for the lower roller gear.
