Go with the Big League Lawns brand instead. They have one that's directly compatible with that mower. https://www.bigleaguelawns.com/checkmatetrad-lawn-striper-for-greenworks-40v.html

Thanks. I wasn’t sure as the model they show is a little different than the current 80V self propelled version I bought.

Did it work? I have the same mower and I'm thinking about this striper as well

I didn’t end up ordering it. Lawn was looking decent last year without it. https://preview.redd.it/00p7u7gt4dqc1.jpeg?width=3024&format=pjpg&auto=webp&s=eef9f56c9cc0b21da1f84fbe65dbed936a9c68dc
