I have a heating issue with a new John Deere 997... see in the pic below, the black mesh screen at the back of the mower...the radiator fan sucks in through that to suck through the radiator. this screen obviously clogs very fast....10mins. about every 1.5 hours it simply overheats. It was suggested I stop every 10 mins and clean it...you can imagine how I felt hearing that! not cheap these units, should be a lot better set up. $30.000 aussie dollars. the screen isn't even the corrugated stuff, just flat screen, bloody amazing! bloody cheap! It's sitting at the dealers waiting for someone to think how to fix it, I think they were going to try to get a new heat switch, this alarm cuts in at 92 degrees and won't cut off. Unless the radiator cap pressure is released which tricks the sensor, then it goes again....this will only allow the alarm to turn off when the correct temp. is reached though. But that's one problem....#2 problem is then how to keep the screen clear so the radiator can breath, as the switch won't cure that, and the bloke reckons 92 sounds about right, but no one knows as info is limited on these at this time. The screen blocks up, radiator fan can't suck in fresh air, so it gets hot. So until deere in America redesigns a better bum for my mower, I'm going to be having problems. Now, I did suggest to dealer I put 1 or 2 of those 12v radiator cooler fans in behind the screen to automatically turn on every few minutes to blow the debris off.....dealer said '' do what ya want mate, but we can't cover it, and doubt a 12v fan could have enough grunt to blow out against the suction that is there!'' We put a towel size cotten rag over the screen yesterday, it sucked it on pretty well, certainly wouldn't fall off....so dunno how good these 12v fans really are? They cost about $100 each....dunno if it is worth trying or not.... Anyone got any ideas? The new Hustler diesels have 2 of these 12volt radiator fans on a auto reverse system, they cool the radiator, then every set interval they reverse for a few seconds to clean it, these are the only fans on their radiator as the engine is sideways, leads me to think these fans providing they are the same as what you can buy from aftermarket auto shops would have plenty of air force. I appreciate any comments, suggestions, feedback, advice.
