in a 165 most folks want the later models that came the a 4 speed trans with h/l.
the earlier models had a 3 speed trans with h/l with multi power.
multi power was a nice feature back in the day, but its old, so if it has multi power really check it out and be sure its working properly.
repairing that multi power trans could add much to the cost of the tractor.
as far as I know most everyone that had a 165 MF liked it.
so if multi power was not working and would not hold the tractor back (motor braking) and the brakes did not work well, you could be up a creek fast.
good luck, hope its a good tractor and you get it.
I have an old TO-35 and guess I will have it until I past,
a 165 would be nice.
