Just answered your IM. If you're experiencing a drive issue I can give you the procedure as per the 3054xs manual, but it doesn't sound like a clutch issue if your PTO still operates, unless the drive clutch itself is compromised, in which case the tractor must be split. Check to determine all drive related controls operate as intended, i.e. the shuttle, high/low range selector and the gear selector itself. I once lost the roll pin that attaches the gear selector on the dash to the transmission; tractor would not move and I was sure I'd really screwed something up until I found the selector moving but the transmission was not shifting. That roll pin still works it way out occasionally and must be reinstalled
