I have an old 632 that is still running good. but just notest that when i let the arms all the way down with the bucket flat on the ground that the hydrilic line running on the under side of the lift arm is hitting on the flange that runs over the top of the tires. is there an adjustment that can be made to kept the arms from droping that low. this cant be the correct stop location when it was new. it has even but a small dent in the hydralic line and i am know woirred that it will wear a hole in it.
