Doing the deck maintenance for the bx2200.. changed out the old worn out blades for new oem Kubota blades, was trying to figure out how the gear box comes off to change the belt, which is in better shape than I thought, had it all lose, decided to check the gear oil in it and it was empty!
Going to put it back together and see how it sounds, the gear box has very little play when turning the driveshaft to when the blades turn.. added the only 80w90 gear oil I have which is Yamaha outboard gear oil so I know that is good stuff.. whatever damage is done is already done.. going to let it sit overnight and see if it is leaking and go from there since I don't have parts for it anyway
I did flush the gear box out and very little metal came out... hopefully it's fine.
Glad I only mowed with it once, maybe 20 min, it is a bit noisy I figured one of the spindle bearings were bad, and ordered a few in anticipation of that.. so I know why it was noisy now..
