B series AC question

[yellowdogsvc]

I still get plenty of water in the cab. Overflows from AC just in front of filter, and runs out under the floormats. Steady stream of cool water so I know it's from AC. Can't find a drain under the cab that I could simply blow out like I do on my bobcat ss. SS have easy access to condenser coils and condensation drain. In fact, I opened and cleaned mine out in 30 minutes including moving machine to flush with water. Don't know where to begin on TC.

Is there a recessed area in the floor where the water sits? Can a small hole be drilled to drain the water out?

Maybe get someone to ride with you and see if they can feel exactly where the water is dripping from.

Or put some papertowel on the floor and see where the first drips appear. Although I have seen cars where condensate water would pool up in part of the duct work and then pour out all at once during a turn or stop.

I will take some picttures. The water pools in the tray where the filter slides in and overflows to the right or left depending on how the machine sits. I put a damp rid in it overnight and will do so. I don't see how I can get a regular drill into the area to create a drain so I am probably going to take it to the shop where they will have a right angle drill. Need to rig it up right so I don't suck dust from the hole straight to the filter.
It would be much easier to find the drain that should be there and unclog it but it has proven elusive.

I understand the immediate fix of draining cab, but why is it in the cab. It would be like drilling a hole in your bedroom so the window air conditioner can drain.

There should be an evaporator core, generally housed in a plastic or steel box. That is where the condensation forms. There must be a plugged drain hole in that box. Works just like your car or truck. Ask your dealer. He should know where the drain hole is located. Maybe remove the filter and look in the box.

I found a small hole on the side of the tray that the condenser sits in. The hole spills over to the floorboard.. what's up with that.

I may have to take everything apart and look for the drain. I understand how AC works and it makes no sense not to have a drain. ON the b series, the AC straddles the middle of the cab. A metal sided filter slides in from driver's side and is secured with tough velcro. There is room for water to collect but it doesn't seem to go anywhere fast. I'm guessing there isn't a good hole to drain and/or it is clogged with dirt and mud like my skidsteers do. If I could see it, I could blow it out with an airgun but I can't see anything in front of the condenser coils.

Yellowdogsvc,

I need to do some mowing this week. I will look under mine after running the A/C a while and see where it drains. It's been really hot and humid here so it shouldn't be hard to see where it drains. Mine stays dry as a bone under the in-cab filter.

I did look in the manuals but did not find any reference to the drain. I wouldn't think you should have to remove the center console to find/clear the drain but if it comes to that I can post the steps if you don't have the service manual.

dsb, thanks. My filter stays wet and then it isn't as efficient. When my drains were stopped up on my skidsteer, I could really feel the difference in the cab.

Yellowdogsvc,

I've never cleaned my drain, never even thought of it actually, but my filter stays dry and even in the hot muggy weather we are having I only run the the blower on low with the AC and it's very comfortable. Yours should be no different. I do pull out the primary and secondary filters periodically to clean them but never find much. The door covering the condensor....now that's a different story.
