Harry, Frank.
To Quote Harry: "Frank - yes the 147 as well as all the other tractors in the 1x6/7 series (including the 73)requires that extra frame bracket in order to mount the cast iron lever for the 3-point sleeve hitch. None of the other NF require it." end quote.
The 73 Does Not need the extra frame bracket to install the 3 point hitch. The fender pan/deck used on the other models in the series is what requires the bracket because the fender pan blocks access to the rear of the frame. The 73 used the same basic low tunnel frame and round fenders as the other 7 hp NF models (70/100, 71, 72), and the 3 point casting attaches to the seat mount on those models. That seat mount is not present on the other models in the series that use the fender pan/deck.
