Lazer drive belt and mower belt

[Murphys law]

afternoon gentlemen, I just purchased an exmark lazer 60 in Lz25kc603 and it didnt come with and engine. I found a 27hp kohler but my issue now is the belts. it has the deck belt on the back with the electric clutch. and the drive belt for the pumps is on the front. Im confused as to how i can power the deck and pumps. do i need 2 engines? is there a dual shaft horizontal enging? how does this work? thanks
