My Kubota dealer says that they fill tires with MAG and its included with the price of the tractor. I have been searching for MAG and have not found a reference to it in regards to ballast or tires. I am guessing it is an acronym for a chemical of some kind? Is this a good thing?
In the old days - salt water was added as ballast - worked great, did not freeze until super cold too.
Only down fall ..... It will eat up a rim !!! It will take years, many years, but will eat a rim up!!! SO tubes are typically used and then the salt is placed in there..... problem solved!
Now magnesium chloride is a little different animal....... still corrosive = but not as bad at the calcium chloride......... same weight too.
The advantage of both is that it weighs a lot more than just water!!!!
BUT the rust factor is something to worry about for the future.
People love RIM GUARD - heavy and does NOT hurt inside tire nor outside when it is spilled out. It is beet juice - sugar ..... it too is heavy. BUT the down side is expense - very costly.
Many use windshield washer fluid .... cheaper - not has heavy however.
I would get those tires ballasted for sure - it helps in several areas of safety. IF all you do is cut grass - then perhaps not.
DO the research on the Magnesium chloride - if you decide to fill, make sure it is only 70-75% full!!!!
Valve at 12 oclock - and only air should come out!!!!
