The sports ball catapult driven by mechanical means disclosed herein may comprise a main body, an arming mechanism, a drive mechanism, a cradle mechanism, and a firing mechanism. The system is designed to operate by purely mechanical means and without power, and is launch speed and launch angle adjustable. The action of the system is such that the arming mechanism may be engaged by a user to apply tension on the cradle mechanism and drive mechanism. The user may then place a ball into the cradle mechanism, and may launch the ball from the system by engaging the firing mechanism. The engaging of the firing mechanism releases the tension in the system, causing the cradle mechanism to accelerate the ball into the air. The entire system is contained within the main body, which is designed to provide an easily moveable, lightweight, and low maintenance solution for achieving such a purpose.
