My am 75 is approaching 100 hours. Today while cutting hay I saw the ! light up and below that the dash read "light 2" . Tractor running fine, temp ok and no other indicators of alarms showing. Good or bad I elected to continue. After a bid the indicator showed "light 1" . No other issues, I continued. After a bit the indicator showed "light 0" . I finished mowing . Drove the tractor home, about 2 miles. When I looked down the ! Was no longer lit and the dash display showed time and temp as it normally does. So, what's up? Is this some type of warning that it's close to 100 hours? I can call the dealer but with everyone's hay season in full swing I doubt I can even get through. Either way I'm baling tomorrow!!
