Headed out to bush hog yesterday and power steering stopped working after about 200 yds. The cooling fan blades had stopped turning. Shut the tractor off and spun the blades by hand. Started the tractor and ran it long enough to get back to the house and unhook the bush hog. Haven't turned a nut yet. Any guesses on what might have happened and what I might find when I get into it? Looked at the IT manual and parts list. Looks like a Woodruff keyed shaft and drive gear. Can I get that shaft out of the governor housing without taking the sheet metal and radiator off? I wonder if I should run it long enough to drive it into the garage. Thanks in advance for your input. Contributors to this forum are a fantastic resource.
