I got a question for all the electricians out there. I got a Sun Joe dethatcher and a big yard. I got it because it works great and its light weight, which means its corded. I got a 100' and a 50' 12 gauge outdoor cord to cover whole yard. When I looked in manual it said not to use more than 100' of cord. Why is that? I'm thinking it would be difficult to supply power that far but I'm no electrician lol. Will I harm my machine if I connect the 2 cords? Any help would appreciate! Stay lifted.
