OK, our friend still has not had the time to work on our tractor( 1994 L3250 Kubota ) for the over heating problem , so hubby looked into it himself ( not very mechanical) . But when he went to check the thermostat..... low and behold it was missing!!! So, I'm no expert, but I'm pretty sure that isn't right.... So what could the people who sold it to us be trying to hide? If we use it w/o the box blade for light use it doesn't get hot. After an 1/2 hour of using the boxblade it does. But our friend said that is an old trick to make it seem like it doesn't overheat...to remove the thermostat... so what should we look for once we replace the thermostat if it continues? m Help!
