This past summer I purchased a Scag Turf Runner off ebay. Big mistake. With even a few leaves on the ground I would have to double cut just to make it look nice. So I had decided to sell it when boom! The two gears on the left side of the deck drive sheared some teeth. I'm thinkin of buying a New John Deere F687 60'' with bagger to replace, but I need to sell this first. Dealer wants $950 for a new gearbox, tried going through Curtis Machine(the manufacture of the gearbox) for parts. They no longer have any gears that will fit because scag changed the gear ratios. Does any one have an old gearbox setting around?
