Expensive but so useful !! I find it amazing, and my lower back is so happy !! I use the mowrator with the auto dumping bag, when it's full, the mower is sent to a big dump bag which has been prepared before, wide open on the ground. I just press the button on the remote control, the auto dumping bag goes to action, and done, the grass is in the big bag, and I can continue my job, and my lower back is happy !! A good investment !
