Mowing Blow out Radiator, Oil Cooler and A/C Condenser Cooler - sandwiched in a Deere 4720

[claitner]

The John Deere 4720 with cab and A/C has the Oil Cooler, A/C Condenser Cooler and Radiator all sandwiched very close together. I can slip the air compressor attached wand between them; but cannot rotate it to effectively direct the air to blow out each of the three sandwiched coolers. Is there a good way to clean them of dust?

Water, but not high pressure.

Dust is easily rinsed from heat exchanger coils unless it's greasy dust, then a detergent is needed as well.

The Hurlimann is a Push through air path for the cooling coils. The fuel tank is "right there" as well. No room for air.

I use the garden hose with a soft spray. Seems to work OK, but this is New England forest, and dust is not something seen a lot.

Hay got rolled up pretty wet all week.

I utilize an air comb on rad.ac cond on my tractors. The holes in side of wand can be aimed by rotating handle.

Don't know if this could be used or not but it works great for me...

I have posted something about this before. My 4320 cab has the same condenser/ oil cooler/ radiator setup that you have. You can easily bend the aluminum fins with using to high of a air pressure. Somewhere I read that something less than 30 PSI air pressure should be used. I have tried un-bolting some of the mountings and spread the radiators apart but not with much success. I now use my shop vac to blow out the radiator from the backside by reversing the hose arrangement. It has a lot of volume but hardly any pressure. I also have a small hose duct taped to one of the shop vac tools to vacuum the lower front corners and bottom part of the radiator where it is exposed. I will also use a water hose if needed. The air filter box that makes up the front portion of the hood arrangement does not seal very well, especially on the bottom shelf where the latch arrangement comes thru. The hanging screen on the radiators is not of much help either. When my tractor was new the hood would catch one of the heater hose towards the back of the engine on the drivers side. The hood would latch but it would not seal hardly at all. This really dirtied up everything when the tractor was new. Now I pull the side of the hood out after latching. That's the end of my complaining. I find most of the debris on the lower portion of the radiators. My tractor even in the hottest weather has never run hot per the gauge. Maybe 3/4 of the sweep at the most. Good luck cleaning. Later.

On my 5520 I had dirt packed between the oil cooler and AC cooler. Had to unbolt the assembly to get the packed dirt out. This is a new to me tractor and had an AC issue.

I use the HF 2' blowgun linked by Turby, and has worked very well for several years..

I avoid water as it makes mud and then cakes up to exist forever.. unless one could blow out the mud with a blowgun.

Just using dry air, is my plan, before making mud cake.
Compressor is set at 90 psi.

Am sure water works ok for some.
