Power take-off shaft drive for an agricultural work machine

A PTO transmission (12) for an agricultural work machine, in particular for a tractor (1), is characterized by a first partial transmission (20) to which a first transmission shaft (27) is assigned, and at least one further partial transmission (30) to which a further transmission shaft (37) spaced from the first transmission shaft (27) is assigned, wherein each of the transmission shafts (27, 37) can be brought into drive connection with a common PTO shaft (11) via at least one transmission gear stage (G n ) and wherein each of the transmission shafts (27; 37) can be brought into drive connection with an input shaft (15, 21) of the PTO transmission (12) by closing a friction clutch (23; 33) assigned to the respective partial transmission (20; 30).
