We have a 4230 John Deere with a Quad Range for sale near to us but according to the owner the tractor has a gearbox problem. The gearbox wont select any gears. The problem must be inside the box, because the owner says the shifters works fine it just isn't selecting any gears. Someone told him it is just two bolts on one of the shafts inside the gearbox, that is loose or broken. I know it is not a lot of info, but has anyone experienced something similar on a JD quad range gearbox?
