We like our deere notill drill and the job it does, but be advised that they can be very expensive to rebuild. If you get a 750 make sure that it is a later model. they have replacable bushings on a few places where the early ones do not. You could talk to someone like churchtown farm equipment because they specialize in deere drills. they might be able to tell you what to look for as far as problems. so far i have used this kit on 2 drills and am guessing that most older drills will need it as well.
