I wonder if they only make the one for the little Ryobi electric ZT?
Criticize all you want, innovation seldom works perfectly the first time yet is the process by which everything good we have today has come into existence. And you can pick anything apart. My great grandfather brought the first steam powered traction drive engine (shortened later to "tractor") to Oklahoma when they first were available... he took a team of draft horses (he was a Percheron breeder and had some world grand champions) from NW OK to Kansas City, MO to get the tractor the 375 miles to his farm because he could pull it back with the team in 1/3 the time the tractor could drive the trip. I can only imagine all the guffaws he received from farmers along the way who couldn't imagine the tractor would EVER replace the horse for farming.
ALL of you tractor owners should be glad folks like my great grandfather and a few others like him had the vision to buy those SLOW, HUGE, under-powered tractors back then or you wouldn't be working and playing with your nice new tractors today.
Innovators are the visionaries we all owe our lifestyle to.
