My 312-A used to do this a lot, so I stopped using it most of the time, just adjusted the height and left it down all the way all the time. I think there's something wrong with the latching mechanism for the handle, but I haven't felt like, or had the time to, pull it apart and try to fix it. I have a GT-1848 and a 416-H both with hydraulic lift that I mow with most of the time now, and much prefer that. Share this post Link to post Share on other sites

Over time, moisture enters the top opening of the manual lift and creates a packing of rust that ends up doing exactly what you described. It happened this winter on my C81 - the plow would drop by itself. There was some discussion on this subject around that time - place a rag or paper towels under the pivot and add a good squirt of penetrating oil or Marvel Mystery oil to free it up. Let that drip out, follow up with 90 weight gear oil. Did mine, no issues... 1 Share this post Link to post Share on other sites
moe1965 740 #5 Posted July 5, 2023 The slot that it clicks into down by the adjustment knob might be worn out. It can be removed and a little dab of weld and a grinder will fix it up if this is where the issue is. Assuming yours is a manual lift 2 Share this post Link to post Share on other sites

Without looking at the manual, I think you would have to at least pull the running board to remove that side panel. Maybe the seat and the rear fender too. Good opportunity to clean out the leaves and maybe mouse nests that magically grow in there.... Share this post Link to post Share on other sites
