Thanks for showing us how it's assembled. This is the Generation 1 model: 14-inch width, height lever on the right. Gen. 2 (2023) has a 15-inch width, a brushless motor, and a lever on the left. But replacement parts are more readily available for Gen. 1.
Thanks for your video! May I ask how big your yard is? I have a yard probably under 0.3 acre and wonder if this Dethatcher is enough to do the job one time
