Tire ballast weight

[toomanymachines]

I never stated that fluid makes tires wear... What you misunderstood was that dry tires do not have as much stress on them because they can flex to absorb rocks and lumps in the soil. That is why football players do not suff themselves before they play. Would you like to burst open? the same applies to tires. When they are filled to above the rim or very near it you have a very small envelope of a gas.. (air) liquid does not flex. When you drive over something the pressure spikes, stressing the tire.
Most new tractor come with weights around Manitoba. Between radials and lower pressure, traction is attained with that. If you need that much ballast you are pulling too much.
My father ran a tire shop for 39 years, and I continue. I am now 47 so between the two of us we have seen a lot.

Calcium Chloride mixes 150 lbs per barrel.. so we would put about 40 imp gallons and the rest water. that would be 550 lbs for a full barrel. That was always strong enough to prevent freezing at minus 40. I did know of someone who did flatten their tires on a 4wd. They had it parked in a shop (cold) all winter. They had to take it out one early march day, went down the road with it and had the 4 wet tires start leaking. I guess from sitting many months the salt started to settle or was never strong enough and formed ice at the top. When they drove it down the road the chunks of ice smashed the tube against the rim.
I have taken a few tires apart in the winter and early spring that did not have strong enough fluid. Had chunks of ice in the tube about the size of pails

I understand that the larger AG tractors have MUCH heavier weights avaiable to them. My owners manual stated that I have to have 1500lbs of ballast in the tires, plus another 200lbs of wheel weights and another 2k lbs on the three point hitch to run my loader. How in the world do you get 1500lbs of weight on the tires when the wheel is only rated to handle 2 95lb iron weights per wheel? Liquid ballast is not optional on the smaller machines to get them ballasted correctly.

It sounds like you manual is asking for too much.. 2000 lbs on the three point hitch? and that is way out there. plus the fluid and the weights.
What do you plan to pick up with the machine? How many hp is it and is it a front wheel assist? They are suggesting 3700 lbs of weight? With a laaarge portion of that very far back.
from the way you are suggesting you should be able to pick up two large round bales with your loader.
Remember that the front axle is the pivot point, and think of the leverage from that point forward and that point backward. You have far more leverage to the rear.

The tire ballast chart from Messicks says that your 16.9x30 rear tires will hold 609# per tire (water ballast)+ your 190# of steel weights would just about get you to the 1500# per tire per manufacturer. I rather doubt that using the max ballast in tires and the 2000 # rear 3PH ballast is required to operate your FEL safely in most instances. Perhaps if you are loading it to the max capacity of lift at all times you would need that amount but hardly anyone uses their FEL lifting the max capacity ALL the time. The 2000 # ballast on the 3 PH needs much clarification, ie if you have a ballast box staged basically between the lift arms, you wont get as much counter-leverage off the front wheels as having a 2000# bush hog or other long implement hanging back behind you. I would dare say that a 1000# bush hog would give as much countering force as a 2000# ballast box.

That's not exactly true. The pivot point for the FEL and the weight is lifts is the loader mounting arms which are located more centrally on the machine. The front tires are more like a cam over point. There's not as much weight too the rear of the pivot point as you suggest.

Still, that does seem like a lot of rear ballast to me too. It is possible he might have mis-read the manual. Mine have all given an either/or scenario ie; a certain number of specified weights per rim & tires filled with fluid OR a certain amount of weight on the 3 pt, OR any combo of either that gives the required rear ballast.

Your tractor has 2 pivot points when using the FEL, the first being the front axle that takes all the weight of the tractor/wheel weights/liquid ballast + what ever you are lifting with the FEL. The only way to remove some of that weight it to put a counter weight behind the rear axle so that it becomes a secondary pivot point which is what JD wants you to do by adding 2000# to the 3 PH. You need much of your ballast weight on the 3 PH lift arms rather than on the rear tires. While weight on the tires will keep the tires on the ground, it does nothing for unloading the front axles, in fact it allows extra force to be applied before the rear wheels will become unstable and rise off the ground.
Adding weight to the 3 PH lift arms takes that amount of force off the front axle which is what you want to do when using the FEL. The further back from the rear axle this load is centered, the more counter-active force is applied to the front axle so the better it is for your tractor.

The operators manual for the 563 loader is where I am quoting the specs from and yes it does call for that much weight. The loader has a capacity somewhere in the neighborhood of 4klbs (a little bit higher I believe) Its a 5083E. The 3pt hitch is rated to lift 3200lbs at 24" so no 2klbs is not asking anything of that machine.



Currently I have Rim guard in the rear tires whigh gives me 800lbs per rear tire, not 600. I am also running a 1700lb concrete counter weight and with the 563 NSL I have managed to pick the rear end up off the ground so don't tell me I am running to much ballast. I'm just telling you guys what my loader manual is stating the MINIMUM requirements for safe operation of the JD loader that is spec'd out to run on my 5083E tractor. I can scan the page if you think I'm nuts.


I think we are getting a bit off topic from the OP though.

No, I don't think you're nuts if you were referring to me. Just saying it doesn't hurt to double check the manual sometimes. I wasn't sure which of the tractors listed in your sig line you were referring to, but can definitely see the weight being needed for the 5000 series machines and loaders. I am surprised that they only say two weights can be mounted on your rear rims though. My manual for my 4500 called for three 110 lb weights per side on the rear rims. Your center dish/plate is every bit as thick as the ones on my 4500 were, maybe thicker, so I wouldn't think it would hurt anything. I have here a bunch of old JD brochures that show the 5X10 and 5X20 series machines with 3 of the same exact 110 lb weights I had per side in the pics, and have seen them set up that way at several of the large dealers around here. Have any idea why you can't do the same thing with yours?
