The invention relates to a groundspeed power take-off (PTO) shaft arrangement in a commercial agricultural vehicle. The groundspeed PTO shaft arrangement has a groundspeed PTO shaft device with a differential gear (222). The differential gear contains an input shaft (221) which is coupled to a gear (212). A right wheel output shaft (232) is coupled to an end drive (233) of a right wheel (234) and driven via the input shaft (221); a left wheel output shaft (239) is coupled to an end drive of a left wheel and is driven via the input shaft (221). Provided in this case is a first PTO shaft (236) which issues from the differential gear (222) relative to the input shaft (221), is driven by the input shaft (221) and is coupled to the right or left wheel output shaft (232, 239).
