On this tractor, you cannot change the pulley on the tractor. The pulley on the deck should be about 5" in diameter. If this is correct, I have a couple of dumb questions. Are you sure you have the correct blades? They have to be LEFT hand cut. There are Allis-Chalmers 48" decks with a right hand cut and they will fit as they have the same bolt pattern. Are you sure you have the right twist in the belt to get the proper rotation? The pulley and blades should be spinning counter-clockwise. Pat

One other thing to consider.Many people control the ground speed with the throttle.Throttle should be wide open,or close to it,and groundspeed controlled with the hydro lever.

I bought a deck last year. The seller told me he had aquired it from his neighbor after his neighbor was unsatisfied with how it was cutting. The guy had used it for one year and then threw it in the basement because it didnt cut right. He bought a gang mower to do a better job.... When I went to pick up the deck, the blades were on upside down. It mows great now!!!

        Over a year ago, you answered a question I had about the tool bar for my FDT. In your reply dated Dec 31, 2019  you said the spacer, part #16, goes in the bar to allow for up and down depth adjustment. does this mean the bolt has to be tightened at whatever depth desired or does the bolt slide up and down, allowing the lower hitch to free float?
         If it is tightened so the lower hitch and the bar are rigid, then is the depth to be controlled by the shoes? Or by the lift handle?
        Is there any kind of user directions for the tool bar? The Outdoor Power Manual basically shows how to assemble the bar but not how to use it
