Just saw your thread. Is this the one Kahn had on their lot with no oil in the bar? Anyway, I have a Gehl 1080 (Vicon KM240). The conditioner rollers have some play normally. The only way it wouldn't be driven would be if the roll pins were sheared, spline shaft stripped or drive gear stripped. There are almost no parts left for these. To remove the roller you will have to take the right side of the machine completely off. Then the rollers will just pull out. Tractor Supply has blades and bolts for these. I ordered some parts from a distributor in Canada that used to carry Vicon and has some parts in stock. I have had little luck in this area (Cummings and Bricker is the distributor here) with our area dealers.
