Note : The recommended PTO ratio is 1.29 : 1 (129%).
The recommended engine idle speed with this PTO is 750 RPM.
This will result in a 968 RPM pump drive input, thereby insuring 5KW
of available power at engine idle. If full output is required at idle speed, then a higher PTO
ratio must be chosen to create 1200 RPM pump drive at idle speed; however care must
be taken to prevent higher engine speeds from creating a pump speed that exceeds the
pump’s maximum speed.
