I have a JP Super push mower that has a problem with rear roller not turning. I suspect something has seized up or broken in the gearbox within central roller.
My question is, how do you get the mower apart??? The cross shafts are held in place by cotters, but these appear to be almost impossible to slacken off and remove. I have managed to remove one cotter sleeve on axle for rear roller but cannot remove cotter bolt. So far I have had no luck with any of the other cotters.
