See, I suffer the same fate all the time when haying. The chaff migrates into the radiator net or the intercooler or the condensor and there is no air compressor out in the field for a quick blow off.
I have limited success with the cordless leaf blower I use on the knotters on the 575. My electric auxillary fan setup works and it's electrically reversable but it only gets the condensor/intercooler, not the radiator itself and both radiators (9000 and 105) bet loaded with chaff, especially in the bottom third.
When the radiator gets loaded, flow from the fan is diminished (through the intercooler and condensor and to a lesser extent, the transmission cooler) so things heat up, in the cab and in the gearbox and I tend to use the hydraulics (which generate heat) more in dusty, chaff laden conditions, like moving rounds from the field to the trailers where driving across the bailed fields stirs up the chaff left on the ground by the bailing operation and even more so when bailing wheat straw behind a rotary combine.
I'm pretty happy with the electric fan mod but it's not a pancea for everything. I still have to blow out the radiator every night. It's a ritual along with greasing the front axle pivots and checking the lubricant levels.
All in all, it's better than the 5030 was but still a PITA.
Deere has it right with reverse flow fans and I've seen reversable fans for tractors, but never Kubota's plus I suspect they are pricey.
I apologize for hi-jacking the thread as this is about a 5030, not our larger tractors. I always liked my 5030. It just wasn't big enough to run my equipment. I found myself many times with the engine wide open trying to hold 540 pto. That don't work, both from a longevity standpoint and a fuel consumption standpoint.
