I have had 2 krone mowers, they were good mowers, wore both of them out, we cut 300 acres 3-4 times per year, always try to run 2 mowers, however, both did end up having gear box go out, fixed them both 2 times last time I bought a new Kuhn to replace one of them, we got several years of service from them, I like the Kuhn better, but it is a newer cutter , I had a belt drive and a shaft drive krone , seems the belt drive gave less gear box issues , since the shaft was a direct drive , it was harder on the box,
