I too have had the radiator blocked by all sorts of crud kicked up by my bush hog. One of my pet peeves with my B7300 is there is no temp gauge, (another is no dash lights). While the radiator vent 'heat whistle' it is very hard to hear over the noise of the tractor and whatever implement I am running. I am training my grandson, who now likes to 'help me' mow the lawn, that during dandelion season to stop frequently and blow the crud off the radiator and screens, etc. I do not know what I would do if it did not have the screens near the radiator. He has really caught on to that, as last time he mowed during dandelion season, he stopped on his own 2 times without being told and blew it out. I am also inline with others in keeping the bucket on and low while mowing. I carry a pry bar and often times pry rocks and get them into the bucket so as not to hit them next time mowing. I also keep my jug of ice water in the bucket. Handy on warm dry days.
