This is our 3rd year with our R7. What a step up from my old N6! Engine is excellent if it had any care for it. If you are not familiar with the rotory series there is a bit of a learning curve, good idea to find a shop manual. The first time I changed a rotor belt I did not know about checking the gearbox shaft for end play, that belt lasted about 100 yards down the field. The engine compartments look like they are designed to be self cleaning but I still have a lot of problems with build up especially in wheat when it is dry. Otherwise like others have said, its only as good as how the last owner treated it.
