I just bought a 1972 Wheel Horse Charger 12 with a 42" side discharge and rear leaf blower attached. When looking under the unit where the deck is attached to the tractor I see it only attached to the front (towards the front wheels) nothing attached to the rear. Isn't this deck supposed to be attached to the rear extension arm? Looks like there is a pin on the deck
that would attach to this arm. Am I right?
