Hello Peeps! I wonder if you can help me please? I have 2 lawn mowers, one is a Flymo turbo 300 and the other is a Flymo turbo 350. Both are the push variety, not hover. I just wanted to know if the cutting blades (?) are interchangeable? Please? One mower works and the other is about to be ditched, but obviously, if I can steal any parts from one, for the other, that would be good. Thank you for your knowledge x
