B7500 w/60\" MMM Do I have the wrong PTO shaft?

I bought the tractor in March and didn't attempt to mount the mower deck until now. The guy i bought it from said that when he bought the tractor (used with 40 hrs), he immediately took off the deck off because he had no use for it. I think he may have given me the wrong shaft or he never had the correct shaft to begin with.

I put a floor jack under my B7500 and didn't have much trouble getting the deck in position. When I went to slip the PTO shaft on the deck's shaft, I noticed a problem. The PTO shaft has splines all the way around except for one area where there is a "notch" which is the width of about two splines. The shaft on the deck has splines only, with no notch. Needless to say, I couldn't get them to slip on.

So, can anyone shed some light? My guess is that I have to get a PTO shaft with splines only, no notch. Can anyone confirm. Also, if you have a B7500 with the 60"mmm, how long is the shaft?

The "notch" that your looking for on the pto shaft is actually a small weld bead inside of the coupler. Keep rotating the shaft on the splines and eventually it will slide on to the shaft. Bear in mind that it will probably be a tight fit until you get some hours on it as the splines wear in a little. Once you've done it a few times it will get much easier!!

I attached a quick drawing of the mower deck shaft (all splines) and the PTO shaft (splines with "notch"). Is this correct?
