@ BWS: I have no idea, thats what im hoping to find out. This thrower has what I believe is called the "quick latch" attachment. not sure if its considered part of the thrower or the push bar. Its really cool though because once u have the push bar attached to the belly of the tractor, u can literally attach the thrower in about 30 seconds. U drive the wedge on the push bar into the reciever on the thrower, throw the lever, jam the pin through, and attach the driveshaft. DONE! Whats bad *** about that is you can quickly detach that pregnant Yak sized thrower when u dont need it, which allows u to drive it into say the corner of the garage, drop it and then store the tractor easily elsewhere.
This poor thing sat outside its whole life. If i would have bought it new, it would still look new. I am planning a full restore as soon as I find the time.
Thats all for now, more pics to come!
