After scanning through my literature I'm pretty sure I have every manual for the Bolens push mowers and could not find one exactly like this. I then went to my Propulsion engine literature which was a separate company ran by FMC that made the same mowers but put different colors and brand names on them, I think I found a partslist!
Need more info to go forward though, what is the size of the cut 19'' 21'' or 22''
A good pic of the handle bars.
Is that engine a 6BHS ?
