Rotary Mower Speed

Picked up an old rotary mower, been repainted IH red and can find no numbers, labels, etc. How do I determine if it is a 540 or 1000 rpm gearbox?

Is the PTO shaft present?

If it's old and under 15' odds are it's 540.

The splines on the end of the PTO shaft would tell you.

Learn something everyday. Didn't know the splines were different. Thanks

Male spline on older tractor for 540 is 6 splines & 1000 rpm is 21 splines. Some foreign to USA tractors built recently had 3 different speeds utilizing the same male pto shaft on tractor
