a pulley and a wedge

a wheel and axle and a block and tackle

The correct answer is a pulley and a wheel and axle.

Explanation:

Pull start lawnmowers usually have a traction mechanism designed to turn on the axle of the crankshaft and start the lawnmower engine. Also known as a recoil starter, the traction mechanism consists of a few different parts that work together to allow the user to start the mower engine.

The casing contains the pulley, starter cord, and rewind spring, all of which work together to form the mower's traction mechanism.

The wheels allow the machine to be moved on the ground.
