Super A hydraulic lever

asyrp43 · Jun 6, 2008

I've been working on my grandfathers tractor and recently the hyrdaulic lever that raises and lowers the rear plows has become very loose. It always falls down to drop the plows. I haven't messed with it much because I wanted to check here first. Is there something to tighten that will make it stay. Also the lever for the front plows it a little tight. It works fine but not as smoothly as the rear lever use to work. Any help would be great! thanks!

asyrp43: Those levers have double locking nuts on the pivot shaft, and a friction pad behind round base of lever. The double nut changes tension on the friction pad. Between the nuts and friction pads are a sleeve, cotter pin and spring.

You could also have friction pads worn out. Also the sleeve, sometime those rust freeze to pivot shaft. If that happens the best cure is dismantle the lever assembly, clean it up good, replace spring and friction pad. Those don't adjust accurately if rusted badly.

I've replaced the springs and friction pads on my SA and 130, however not the 140 yet. They seem to work well for 40 years. It's not a bad job getting them apart, there is a roll pin in base of lever, through the shaft.

Thanks Hugh for all the information! I worked on it this weekend and it works great now. I also came across the original owners manual so that will help me a lot. Thanks again!
