Might also add - did you release the brake?

Here is the procedure from the service manual - attached For the earlier models but should be very similar on later ones. Get a manual - they are free from Deere.

Thank you for the procedure - we searched for a service manual and could only find the owners manual which we have. It doesnt have this in the owners manual. Thank you its very much appreciated.

I think so. With the mower deck removed, the brake lever is in the locked position and behaves differently than when the mower is attached. Anyway, the lock handle is down, so I assume I unlocked it.

I replaced the transaxle pulley, transaxle belt, and idler pullys on a JD 2009 X300. I took pics and wrote the whole process down in case I needed to do it again because there is no info anywhere about it. Not sure if I'm any help, but I attached two pics of the transaxle belt installed as they run thru the idler pulleys. Pics were taken laying on the ground looking up at the bottom of the tractor.
In both pics: the "bottom" of the attached pics are going toward rear of tractor and the "top" of the pic is toward the front, you can see daylight in one of the pics because the seat and gas tank are removed.
Also here are the part numbers that I used.
Transaxle Belt P/N: M144044, transaxle pulley P/N: MIU800783, transaxle idler pully P/N: AM138079 and AM 138080, transaxle spring washer P/N: M87534 this washer goes with the transaxle pulley.

Any way I could get a copy of the process? I know you made that post a couple of years ago, but I'd sure appreciate it, and any photos you have. yardscapeelaine at gmail dot com

Thanks in advance!

I'd like to see that detailed write up as I am currently trying to change my main drive belt now. I forgot to take pictures as I always forget to do. I think the two pics you got here my get me over the hump will find out in the morning. Thanks.
