John Deere X758 Radiator Placement reason .

Never had a problem. Neighbor has 2 x7** and mows a lot, I have a x744 and dad has a x749 and we have not had a problem.

Do the screens on the rear mounted radiators and filters ever cause anyone problems in freezing weather freezing over during snow falls and or frosty air conditions ice build ups freezing moisture etc. Is there anyway low air flow restriction in cold temperatures cause an over heating situation due to low airflow ?

No

^^^^Agreeing with beenthere.

I had an aftermarket Cozy Cab on a 425. Cozy had a vinyl cover for the intake screen that was installed with Velcro patches and it's purpose was to block air from entering the suction screen. It helped keep the cab a little warmer in the winter.

My brother in laws JD 748, is like that. What I don't understand is why they put the electrical fuse box in front of the radiator, in the path of the radiator intake air. This some what dirty air degrades the the electrical circuit over time. This makes it compact but makes it a Mickey Mouse design.

Don't find that to be a problem. But do blow that area out each time I open the hood and use compressed air blow gun to remove the debris from the radiator screen and back blow through the radiator to remove fine dust. At the same time blow the dust off the circuit board. This happens after every mowing, before the tractor is put away for the night.

And for sure, do not spray that area down with water that just mixes with the dust and causes mud.

Yep...same here.

I forgot to clarify that this JD 748 has a Cozy cab. The rad screen does not come out easily because of the foot well structure and there is additional wiring because of the cab. A blow gun and a aluminum finned radiator are not a good mix.

Guess you need to find a way around the problem. Since 1998, have had several Deere lawn tractors of this frame size and not a single problem using the blow gun to blow out the radiator. Good judgement is needed as to pressure used and distance from the fins, for sure.

Thanks guys I sure like hearing what you have to say....it's good info.

Here is what I use to clean my tractor radiator. I use my shop vac. I reverse the the hose connection to blow versus vacuum. You get a large volume of low pressure air that way. It a Craftsman either 5.5 hp.
