So my parents gave me their old craftsman ride on and it has been working great for the last year and a half but lately it’s been making some weird noises, the blade has play before the pulley actually spins I made sure everything was tight and it still does it, I’m also wondering where to get parts for this thing, I’ve checked sears parts direct and no mention of this model number and even google. The closest I can find would be the second picture but the model numbers are different and just helps me with maintenance. I’m hoping someone knows if I they parts on the different models are interchangeable.
