I talked the the seller I asked him about the shape it was in and he said that it was in good working shape he had it on his own tractor last year. ... Or does he have the LGT 120 I might have to call back before my cousin makes the transaction
I think i looked at this last year, if it is the one in the post i made above it is the same style tractor as your 140. I didn't look at the deck but did see it mounted on the tractor. Whether or not it will work on your 140 depends on if you have the same brackets under your tractor but it was mounted on a similar style tractor to yours, the 60's older style. Nice guy to talk to btw.
Just talked to the seller again. Feel like I'm irritating him but he was fine with it. He said it was the 1969 Ford 120 he had not the LGT 120 so that set my mind at eas a bit. I might be lucking out also because I asked him if I was going to need some kind of Sleeve hitch for the tiller he said that i shouldn't because it had a triangle piece that he is sending with the tiller that fits the back of the tractor it just needs a bolt. I think that is the sleeve hitch I be leave not sure though until I see it.
The tiller has a subframe that bolts onto the back of the tractor where the drawbar goes, just remove the drawbar with the ball hitch and bolt the tiller subframe in its place. Heavy but with a floor jack not hard to do. There is no sleeve hitch with the older tillers like this. The tiller comes with its own subframe and pivots on that. With the tiller mounted you won't have a ball for towing and it takes a while to take on/off the tractor, line up the bolt holes, etc. Good luck-
