so my towner disc harrow is almost exactly the same as this one I found online...http://www.flickr.com/photos/54477575@N05/5047155761/in/photostream/
that one seems to have some extra bars I don't have on my 3 point lift, http://www.flickr.com/photos/54477575@N05/5047776090/in/photostream/http://www.flickr.com/photos/54477575@N05/5047731712/in/photostream/
(outside anti-sway bars on the bottom, and an additional pivot arm on the top)
yet, my lift seems to be able to lift this thing, although its obviously very heavy. if I idle the rear drive with with it up, it does slip down over 5-10 minutes.
I did break a bolt that was holding the anti-sway chains today (the chain was secured to the lug on the lift arm with a sacrificial bolt). This post was edited by pierce at 01:40:55 08/29/13.
