KC9KAS 4,741 #1 Posted March 25, 2010 While working my 654 with the dethatcher, the lift lever height adjustment knob unscrewed itself and fell off of the tractor, as well as the threaded "L" bolt. Fortunately, I found both pieces, but I was wondering what can be done to keep this from happening again. I experienced the same problem while snow plowing this past winter. Ideas??

Kelly 1,029 #2 Posted March 25, 2010 I have a few with lock nuts installed on top of the knob not as easy to adjust but won't fall apart Share this post Link to post Share on other sites
KC9KAS 4,741 #3 Posted March 25, 2010 Yeah, I thought of a jam nut, but would have to carry my "save the world" wrench (4" adjustable wrench) all the time. A lock nut (nylon insert) epoxied to the knob would work, but in time with a lot of use, it will become loose. Share this post Link to post Share on other sites
C-Series14 15 #4 Posted March 25, 2010 On the C-Series, I use the little black plastic cap that goes on the lift lever release button to put over the end of the threaded "L" rod...at least that is what it looks like is on there!!! :omg: Share this post Link to post Share on other sites
