I have a M6800. The lift lever only works on the last (upper) inch. This only allows about 5" of clearance on my Bushog when in the highest position. This position used to be about 1/3 up from the bottom. If I don't have an impliment on, the arms will go nearly to the ground. I have checked the hydraulic fluid and it is full when checked cold and not operating. There are no adjustments in the external linkage. I did recently have a problem with this lever being practically frozen up. I decreased the spring pressure and sprayed penetrant on it where it goes into the case. It took a few days but works very freely now. There is no indication that the lever has been bent. It has about 750 hours on it. I am not the only user.
