I took the steel kett for a spin today after having done a long trip on the Kross. If you are thinking of buying a kross consider carefully.
I love it. it is a chunky tractor, a princess that needs a lot of fettling and has broken down badly alot.
It is however not a patch on the old steel ketts. they are so fast by comparison. I think their overall lightness and maneuverability shine though. That and they can be picked up for an eighth of the price secondhand.
I wonder what the newer ketts are like?
