A tamper conversion method includes providing a tamper including a ramming apparatus having a tamper foot and a gasoline-powered engine system to drive the ramming apparatus to reciprocate the tamper foot for tamping, removing the gasoline-powered engine system from the tamper exposing an engine mount, coupling a mounting plate to the engine mount, coupling an adapter plate to the mounting plate, coupling a pneumatic engine to the adapter plate operatively coupling the pneumatic engine to the ramming apparatus to drive the ramming apparatus to reciprocate the tamper foot for tamping, and coupling a conduit, formed with a pneumatic throttle, to the pneumatic engine, the conduit for applying pressurized air to the pneumatic engine to activate the pneumatic engine, and the pneumatic throttle operable for controlling the flow of pressurized air to the pneumatic engine to drive the ramming apparatus to reciprocate the tamper foot.
