rocko 0 Posted October 24, 2005 Hi, does anyone know the procedure for checking the gearbox fluid level and adding oil to it on a Sunstar 60" mower deck. I can't seem to find anything in my manual that covers this. Any help would be appreciated. Thanks Mark. Share this post Link to post Share on other sites

WITom 0 Posted October 25, 2005 Most gearboxes require fluid up to the bottom of the plug hole. If there is a plug in the top, remove that as well as the side plug. Add oil slowly until is starts to seep out the side hole (while deck is level, of course) and replace plugs. WITom Share this post Link to post Share on other sites
