The handle has folding knobs that might not be fully locked. Let's get it solid.
You'll need to locate the handle adjustment knobs. Here's the step-by-step:
- Stand behind the mower and look at the base of the upper handle, where it connects to the mower deck.
- You should see one or two large plastic knobs. These are the folding/locking mechanisms.
- Turn the knob(s) clockwise to tighten. You should feel resistance as it locks the handle firmly in the operating position.
- Try to wiggle the handle. There should be minimal play. If it's still loose, check if the knob is stripped or damaged.
If that didn't work: If the knob is stripped or the handle connection point is cracked, you'll need a replacement part. Contact Greenworks customer service with your model number (MO40L03).
Heads up: Always ensure the handle is securely locked before starting the mower. A loose handle is a safety hazard.
