John, when I had N6113 I put a longer bolt thru the tailwheel and included some washers on the outside and even rounded the tips off some to help the tailwheel tow bar to have something a little more substantial to hold on to. That helps a lot.
Then as you know, I sold N6113 (I'm still regretting that...) and bought a Cessna 180 and figured there is no way I'm going to man handle that thing in and out of the hanger. Specially in the winter if we get a little bit of snow. So I purchased a BEST TUGS A3 tug and the easiest thing I can say. That thing is amazing! You couldn't ask for a better thought out better designed better performing tug. Well worth the investment. It will last you a lifetime!
