I have a John Deere 2653B "precision cut" reel mower that my crew noticed is somehow either consuming or leaking hyd. oil. I have looked over all of the hyd. lines connections, hoses, and various hyd. motors, but cannot find a leak anywhere. Does anyone know if these machines somehow consume oil, or do they have common locations that leak which are difficult to spot? The loss of oil isn't terrible, maybe a cup or so each week, but I'd still like to know where it's going. I'd appreciate any help in troubleshooting this. Thanks!
