I agree. I recently traded in my 30 year old JD 850 for a new Kubota. The JD had the hand crank and I was a bit stunned when looking at new tractors (JD, Kubota, and Kioti/Bobcat) and they all had that painful, inconvenient turnbuckle style arm. I had assumed that time brought progress and better products, but in this case it went backwards. I asked the JD dealer what happened and he just shrugged his shoulders and said this was the new standard.
Retrofitting or a home-business of fabricating is a good idea.
