How to attach the blade to my Sun Joe electric wired lawn mower? I may be missing a bolt or screw.
The picture shows the mower, the blade and a cap which fits. But if I just put the cap, it will come off.

The central bolt and washers in the correct order are used to hold the blade to the mounting plate. The pins on the mounting plate, some of which may be broken in your case, fit into the off center holes on the blade so that the bolt need only keep the blade pinned to the plate and the pins support the torque. Inspect carefully. If you have missing or broken pins, your mounting plate or mower need to be repaired or replaced.
I discovered that Sun Joe no longer sells the needed replacement parts for this model. This is the reason why I decided to fix it this way.
I used two stainless steel washers and a nut (from Home Depot) to replace the original plastic nut sitting behind the washers. I needed a pick to help me route the zip ties after I drilled two holes on the plastic back plate. The zip ties replace the function of the damaged pegs which use to hold the blade in place. The bolt should be tight enough to hold the blade in place so the zip ties should receive little stress during operation.
I've got same problem. I visualized same washer solution but instead of zip ties use small nut & bolt in a drilled hole (pair) on mount; keep bolt tight on washer.
Should work in light usage (thats all this mower for anyway!)
