I have a new to me F3080 mower with caba nd have been super pleased with it thus far. The belt shredded after the second mowing and I also noticed the gearbox leaking out the bottom. I would prefer to find a gearbox to replace this one with and then rebuild the one I have. Does anyone know of the best place to purchase these gearboxes and /or the rebuild kits? or if there is anyone with a used deck I would be interested in purchasing the entire deck. thanks!
