Dad bought a massey Ferg. couple years ago. Noticed left "driverside" rear tire is low. Tried to put air wouldnt take any in. Tried to remove valve stem could budge the stem. This tire is filled with calcium. Air seems to be leaking out of the stem. So can we but valve stem on top, jack up tire, drill out old stem and put new in?? Also are most tractor tires tubed?? esp. those with calcium??

All calcium filled tires are tubed or the solution would destroy the rim. You can't drill it out. I would think that would be very dangerous anyway. I think you have to find a way to work the valve free and put air in. If you get the valve gut out you will have calcium gushing out, jacked up or not.
I'm anxious to see what other people say, here.

The vast majority of CaCl filled tires have tubes, but not all - it won't rust the rim if the rim is completly covered (inside) all the time - it needs air contact to rust. If tubed, you can ususally jack it up with the valve at the 12 o'clock postion without it leaking fluid. Most rear tractor valve stems can be replaced. I'd replace the whole stem.

Are you trying to just take the valve core out of it? They're a 2 piece stem. There's a lock ring where it goes through the rim,then a removable stem that screws into it right there.Leave that lock ring on it. Some of those stems screw in to the inside,some screw over the outside. That's where you need to be trying to take it apart. And yes,jack it up with the stem at the top while you're doing this.
Maybe snap a pair of needle nose Vice Grips just above that lock ring,then try to turn the stem with channel locks.

yes trying just to replace the core.. That seems to be where the air is coming out from..

Not all calcium filled tires are tubed. My neighbors 10 year old tractor has calcium in and it is tubless and the rim is not rusting away.

I did not know you could do that....I learned something.

I purchased a MF 240 about 5 years ago. Calcium in tires from dealer new, with no tubes and the rims a rusty mess on the inside.
Had them unmounted , spent alot of time cleaning the rim, also some welding and 3 coats of rustolum paint and new tubes. Adjustable rims are espensive.

Hansen, the tire is not full of fluid. If filled correctly, it is filled up to the top of the rim. With the valve in the 12.00 o-clock position air is then added to inflate the tire to the correct pressure. If you remove the valve in the 12.00 position with the tractor jacked up, it will release the air, and probably spitt a bit of fluid at you.....that's all. It stings if you get it in your eyes!
