Abstract
A power takeoff mechanism for a farm tractor with two interchangeable power takeoff shafts which can be driven at different speeds and are connected by means of annular flanges of different diameters with a driving flange on the end of an output shaft wherein a pawl is pivoted near the driving flange and is connected to a clutch lever of the gear shifting mechanism whereby the pawl must be pivoted to a predetermined position when one of the power takeoff shafts is installed, thereby preventing the clutch lever from being operated in a manner to select an inappropriate speed for the installed power takeoff shaft.
