Hello all, got a question. The steering tension and control for one side of my Gravely ZT1640 Kohler recently went out (the mower still turns with the faulty steering, but it over-speeds and is ultra sensitive). I believe that there's some sort of linkage or dampener that is probably the culprit, but looking in my owner's manual troubleshooting guide, this specific problem is not addressed - and looking at the Steering Controls parts diagram, I can't figure out exactly what parts I need to get from my dealer for these repairs. My mower is only 5 years old, and this is either the second or third time that I have had this problem. Previous times I've had the mower serviced and repaired by my local dealer, but this time I need to do these repairs myself and save some money. Any Gravely owners out there can help me out, or even anyone knowledgeable with these ZT steering systems... and there corresponding maintenance issues? Thanks in advance.
