My guess is because when Troy-Bilt was sold to MTD, they decided to make the changes. For what reason is any body`s guess.
As far as I know, the T handle is unavailable from parts retailers. You can get one from E-Bay as you posted. The older T handles should fit on your Horse. You should not need the whole yoke, just the T handle.
