In a previous post I explained or at least thought I did that I have to put lever in exactly the right position to get my bucket to lift. When my tractor was new and for years after I simply pulled to stop and bucket moved as desired. Lately, however, I must pull to stop and then move lever forward very carefully to find the "sweet spot" and bucket will respond but slowly and weakly. After reading many posts about water infiltration and rust I thought perhaps this could be my problem. This is why I thought it might be time to remove valve and give it a proper cleaning and inspection. The parts breakdown PDF does not show great detail and this is why I have posted for additional info before I begin disassembly. Thanks, Kenny
