TonyBer 71 #1 Posted August 27, 2022 (edited) Anyone have a fix for a great running C160 Automatic that picks up speed? When driving in forward the tractor gains speed so I have to mow with one hand on the lever. Any thoughts to correct? Thanks!

pfrederi 17,168 #2 Posted August 27, 2022 (edited) Try adjusting the tension on the motion control. Nut is 1-1/8" the squared end of the collar is 5/8" Edited August 27, 2022 by pfrederi 3 Share this post Link to post Share on other sites

tommcgoo 0 #5 Posted October 27, 2023 I have a c160 automatic that gains and looses speed by itself. The motion control locking nut is tight, so that is not the problem. Could a slightly loose drive belt cause this to happen, or is it a transmission problem ? If it is a trans problem does anyone know what it is and how to repair it. If it is a loose drive that is causing this problem, how do you how much tension the drive belt should have ? Thanks in advance for any help. Share this post Link to post Share on other sites
gt14rider 694 #6 Posted October 27, 2023 This is an oid post, should start a new one. The info on adjustments for motion control is in sundstrand manual. Here's a look at the parts. 1 Share this post Link to post Share on other sites
tommcgoo 0 #7 Posted October 27, 2023 I have checked for cracks and there are none. I have a very tight motion control setting. These are not my problem. I was wondering if a slightly loose belt would cause my tractor to pause when going slow at a slight hill until I increase the speed to slowly climb and when I reach the top it speeds up allot. Also when I am cutting on a flat grade the tractor will also speed up. Does anyone have any other ideas as to what might be the problem and fix ? Share this post Link to post Share on other sites
