This deck has a total of four pillows on the deck itself.i changed both transmission belts and the middle part on the pulley underneath the seat moved freely without being stuck. But I still only have one gear. I have the same speed even though i change gears. I'm very sorry if i aggravate you. But I am not mechanically inclined. So I may say things in a different way. Again I'm sorry if I'm a bit slow when it comes to understanding what you are explaining to me.
Nobody with a genuine problem aggravates us, we are here to help and to learn ( well I am in any case ) and helping you helps me.
However I am confused by your answer what we need to be sure of is the lower belt , the one that goes from the engine to the double pulley under the seat.
Is it like the one in the drawing in reply # 10 or does it just go direct from the engine to the double pulley under the seat with nothing in between ?
We need to know ( well I do at least ) because the Troy-Bilt web site shows both systems when I search with your model & serial number .
Giving you the correct information is less confusing for you & any one else who might end up reading this .
There is no time pressure for us, it is your mower so at your own merry pace is fine with every one ,
No one here charges by the hour for advice
