A PTO support assembly for a work vehicle train includes a work vehicle having a PTO drive shaft and a work implement, towed by the work vehicle, having a PTO shaft. The PTO support assembly has a mounting base with a connection interface coupled to the work implement. A support member is coupled to the mounting base and has a support interface for contacting the PTO shaft. The PTO support is adjustable to a support position in which the support interface is maintained at a height corresponding to a height at which the PTO shaft is engaged with the PTO drive shaft.
