Watch the towing eye length if different to the current tongue length, you may over extend your pto shaft.
Why don't you just get a standard drawbar from a wrecker? Get the 2 pins(2 different lengths) that got with it as well. Fitting is easy, you slide the whole unit(frame and drawbar) under the tractor and lift the back by the end of the drawbar and slid the long pin into the upper holes, then lightly push down on the drawbar to raise the front into the front holes and slid in the short front pin. Then remove the rear pin and raise the rear to the highest setting (drawbar will be level) and refit long pin. Make sure you insert the lynch pin from the front to back(in long and short carrier pin) as long grass can open and remove the lynch pin when inserted from the rear.
There is a "long" and "short" setting for the drawbar length. Try both to see which length the baler runs best on.
