I have an X300 and it won't start. It won't even turn over. I believe its the lever you pull to engage the blade. Is this an easy fix? The place I bought it from wants 6 weeks to fix it.
Try to turn the engine over by hand.
If you can not turn it over the starter won't be able to either .
I always advise JD owners to but the JD technical manual.
If you can read then it will turn you into an expert in no time flat .
