Fluid out of the tire

Is there a adapter that can be screwed into the core part of a rear tube so I can drain without spewing that crap everywhere. I went to two local that did tractor tires at one time and nope they dont want it and won't loan me their gun.

I used to have one that screwed on a water hose but i dont know where it is now. Im pretty sure napa or someplace like that would have one

Seen them at NAPA last week. The ones I have were purchased from Tractor Supply

Interesting to see how people have done it. I have to drain a couple of them to weld rusted out spots and need to do it again on rims I just acquired. I usually let them hang with the valve stem downward and let them drip for days. Refill with a homemade funnel suspended a couple feet above and a section of windshield washer hose. Very slow.

I’ve got to replace a tube in one of my fluid filled tires. My old pump setup gave out finally, so I’m going to experiment with a soda syrup pump, like the convenience stores use for their fountain machines. All plastic, so no metal parts to deteriorate. I can use my air compressor and regulate the pressure down to pump working pressure. They are a diaphragm pump, might take a little bit longer than one of those big fancy pumps, but didn’t cost near as much.

I've drained a few myself - make sure you drain it somewhere away from any plants you want to keep alive. I just used a fuel hose on the stem to let most of it drain out, then a cheap suction tool we had that works off compressed air to get the last of it. Sometimes it creates enough vacuum that it will acutally pull the tire off the bead. A handy way of breaking the bead if you need to dismount it.

But anymore, I just call the local tire shop. They do a road call pretty cheap, and don't charge much to pump out tires. I actually have them coming Wednesday to our Southern farm. They're going to pump the fluid out of three tractors and put a new tube in one of them. Total they quoted me, including the new tube, new calcium adapters, etc, was about $730 CAD (about $530 USD), and the majority of that price is the new tube and diamounting/mounting the tire that's getting the tube. Pumping out the other 5 tires is only a small part of that price. For thst price I deem it no longer worth my time to do myself.

I no longer run fluid in any tractor unless it's a larger tractor used for primary tillage. Any tractor smaller than 60 HP we have is usually used for haying or other field work, and they don't need the ballast for any of that. Even without fluid, I still use some of our smaller units (Allis 180 and Case 630) for pulling a 10' disc and cultivator around just fine. For what we do with them, fluid is just more unnecessary weight for them to lug around. And even if they don't leak, loaded tubes will still cause condensation between tube and rim which will rust out the rim. We used to keep all tires loaded at our Northern farm for more stability on our steep side hills, but we now find setting the wheel tread out a couple inches wider does far more for stability than fluid does.

I've found the 1/4" copper tube after removing the valve stem unit works to get 99.99% of the fluid out. Then once it's all out you can get the the tire off to do needed repair then clean the rim up properly. Getting the rim clean is a must.
