...I don't know what would be a good asking price considering the problem I have with it. I'm still trying to decide between fixing and selling.
The planetary gear set would Not be my first suspect... check linkage adjustments and gear engagement And clutch...
All those are 'relatively' "easy"...
When taking things apart pay particular attention to how all the pieces are arranged, gears, thrust washers shiter forks etc...
Do not use the cast cases to Force things together, it is easy to crack the case if parts do not go back correctly.
As to a local price check wwith the Gravely Club: Gravely Tractor Club - Home
I would definitely Repair something Before trying to sell it... It will be worth more to Many more folks if it is working Plus You may see what a handy machine you have and choose to keep it... :smile:KennyV
