Usually a hard clutch pedal means there could be binding in the cable or linkage. There could also be a blockage or worn seals in the clutch master cylinder. Vehicles that have a servo have no need for a clutch pedal because the computer controls the servo, which shifts the gears.
I would check for binding somewhere or a problem in the clutch master cylinder.
