I have following this thread with some interest. My 20 year old 5300 has had CaCl filled tires since day one. Last year I snagged a valve stem on a branch and tore it. Noticing the leak, I parked it with stem at the top and used a farm jack to take off the weight. A call to the service truck and $140 had me a new tube and they topped it off.
Bottom line, how many people really have much issue with rear flats and corrosion from the "old" type ballast? Have I just been lucky(first time then) or are we just being sold an expensive solution to a problem that does not exist?
Just asking because I'll have to make a decision when the 5095M is ordered. If it hasn't been stated enough, filled tires make for better operation and safety. If you don't have the cash now for the expensive option, then go with CaCl and enjoy 20+ years of enhanced safety and capability and pay for new rims when/ if the time comes!
I'm on my first tractor. Bought it used so I don't know the history.
Rims didn't look bad from the outside - until I poked the rusty areas with a screwdriver and went right through. My rims have rust through where most of the rim bolt receivers are welded to them, and the rims are thinner due to much rusting inside. Inner tube is crusted with rust flakes and the tire bead area also.
I can't say how long it took for this process to occur - the tractor is 50 years old. I suspect with better maintenance, the problems would have been minimal. Far as I can tell, it is all from leakage at the valve stem that resulted even with a valve stem cap.
In my case, the tractor will be at recreational property for the next few years unattended for weeks or months at a time, and parked inside a dirt floor barn. A leak may escape my attention. Seeing firsthand the results, it just doesn't seem like it's worth the risk for me to use CaCl - once bitten, twice shy I guess.
I don't have a loader, so having the max weight possible isn't so much a concern - CaCl has a definite advantage if you need as much ballast as the tires can support.
Also, since I'll be loading the tires myself, WWF is a lot easier to pump in than a thick solution that has to be mixed on site.
That's my opinion and my situation. For me, WWF (or RV antifreeze if I can get it at a good price) is a better solution.
