I'm trying to relate to a pull cord on (as an example) a push mower. The more force you use the easier it cycles; does this mean I am wasting more energy?

That wouldn't be the right way to think about it. A lame example would be you stirring a glass of water with a spoon. The faster you accelerate the spoon, the harder it will be. While the minimum level of energy to stir the water at any given speed will be the same, the act of acceleration is what's affected. Keeping things simple, this is why you see a general % loss factor applied since getting into the fine details is not worth the effort (fluid choice, viscosity, mass of components, etc).
