7800 A/C issue

I realize it's pretty new (only 20 years old) but I
thought maybe someone knew something.

I am having a terrible time keeping the drain lines
for the air conditioner unplugged on the 7800. Right
now I'm haying, but it isn't terribly dusty. I had it at
the dealer for new shifter parts during planting and
had them look at it. They pulled the seat and the
condenser pan and fan were sitting in 2-3 inches of
water. They poured several gallons of water through
it and cleaned up the mold. I can always tell when
it's plugged as it doesn't drip all day and then
dumps at least a gallon when I shut it down.
Apparently the water eventually gets deep enough
that it is able to find its way out where the hoses run
into the air box for the heater core.

There isn't any access from the top so I have been
using fish tape to go up until it unplugs every couple
of days. Has anyone dealt with one of these?
 

Do the drain hoses(parts keys 49 &51) still have the loop in them?

I'm doubting it. I had no idea they were supposed
to! The only reason I say that is that they just swing
free under there and don't seem supported or
looped in any way.

That would keep things from finding its way too far
up there. I guess I need to lay in the dirt with a
flashlight.
 
The loops were put in for a kinda drain trap, but dust lays in them and clogs things up, ,,un-loop them and cut the excess off..
