Power take off shifter arrangement

A transmission of a work vehicle, the transmission comprising:

• a housing defining a rear access opening and a rear cover positioned over the rear access opening;
• and
• a PTO assembly positioned within the housing, the PTO assembly comprising:
• a first gear and a second gear spaced apart about a rotation axis, the first gear having a first annular hub with external splines extending about the rotation axis and the second gear having a second annular hub with external splines extending about the rotation axis;
• a rear PTO arrangement having an output gear driving an output shaft to rotate about the rotation axis, wherein the output shaft extends through the rear cover;
• a middle PTO arrangement having a countershaft gear driven by the second gear to rotate a countershaft arranged in parallel with the output shaft, the countershaft extending along the housing away from the rear PTO arrangement;
• a coupler sleeve having internal splines and external splines and disposed about the rotation axis between the first gear and the second gear, the internal splines of the coupler sleeve being in engagement with the external splines of the first annular hub of the first gear;
• and
• a PTO shifter arrangement having a shifting ring disposed about the rotation axis with internal input splines in sliding engagement with the external splines of the coupler sleeve and with internal output splines spaced apart from the internal input splines along the rotation axis by a gap, the shifting ring being translatable along the rotation axis between a first position, a second position, and a third position such that the internal output splines are engaged with and transfer rotational power to:
• the output gear only when the shifting ring is in the first position, the output gear and the second gear when the shifting ring is in the second position, and the second gear only when the shifting ring is in the third position.
