    Was pushing a brush pile ,heard a faint pop ,just lost left side all hydraulic functions, backed away and shut off ,restarted have zero hydraulics either side,no boom functions. Engine starts runs fine ,safety switch will unlock , move both levers ,no response,no boom functions either . Could it be Engine coupler?

    Welcome to HEF Danny;)!

    If it is not driving, then yes, it could be the coupler. Do note, the hydraulic pump on that machine is also the charge pump for the hydrostats, so if the hydraulic pump fails it will affect the drive.
