Note: The PTO Driveshaft provided with your new machine is sized to fit a standard
category 1 PTO (1-3/8" DIA. x 6" Spline).
The PTO Spline Shaft on the tractor that is to use this machine must rotate
clockwise when viewing the PTO from the rear of the tractor. If the PTO rotates
counterclockwise, you must have your tractor modified by installing a gearbox to
reverse the direction of rotation.
The length of the PTO Driveshaft that is included with your new machine will
work in most instances but may need to be modified. See “Calculating Length of
PTO Shaft needed” for checking the PTO Shaft length desired and then “Modifying
the PTO Shaft if required” instructions if the PTO Shaft is too long.
