the answer to this question is yes but the back tabs off of the deck on the 165hydro have got to be welded on to the deck of the stx38 and the back attachment rods have got to have another hole drill in the end and two spacer blocks (one each side) of two inch square tubing must be fabed to move the location out father apart because the 165 uses the outside of the frame and the stx38 used a different type of lifting system. I did this to my 165 and it has been in service with this deck for about four month now and is doing fine.

how do i check the hydro transmisson fluid on a stx38
I'm currently replacing my transmission pully in my yellow deck John Deere STX38. You can not get to it from under the seat. As far as I can see the only way is to drop the transaxle.
