Its been a rough road for my quest to get a sweeper for my GF1800. It started with half the PTO shaft missing and now I find out due to my own stupidity that the gearbox is seized. I started taking it apart but don't see any parts available other then a new box ($1100) I'm thinking I should abort this project and cut my losses. Has anyone ever had issues with these blowers and repaired the gearbox?
