I posted this a couple days ago as a new thread...may not have been the smartest move but I am new to this type of form. While mowing with my 2007 JD X300 (actually when I was repositioning the tractor) last weekend I completely lost forward, reverse and parking brake. Not really confident that I had the same problem as others who went with the K46 rebuild, I gave it a shot anyway, following the instructions posted by lotsofgreengrass (thanks). I figured, what the heck, it seems to have working for almost everyone else who tried the rebuild, and it probably wouldn't be a complete waste of money either way.
What was unique about my problem, compared to all others who attempted the rebuild, was that I lost all transaxle responsiveness immediately. I didn't notice a gradual loss of power...the unit was whiny and underpowered to begin with. My biggest reason to doubt that a rebuild would fix the issue is because of the immediate loss of F, R and brake and I could push the tractor with the brake engaged.
I have a bad habit of replacing unneeded parts, to substitute for my lack of mechanical troubleshooting skills. I am into this for $180 already. Seeing that I have no brake, I have to assume the failure is within the gears, somewhere after the disk that engages the brake. I didn't see any excessive ware on the gears but you can hear the gears within the transaxle grinding (operating the unit on jacks, the wheels will turn until you apply a small amount of pressure. They are easily stopped and that's when you can hear the grinding.
Any suggestions on what else may need to be replaced? Differential gear?
