Ballasts / Rear weight information

[TomOfTarsus]

Hello,

I've actually e-mailed New Holland because I'd like to know about where the CG of my tractor is, both vertically and axially (i.e. % of wheelbase). I don't have access to scales and have some really steep ground to work on. I figure if I have the information for the tractor, I can get a better idea of how to ballast.

& Thanks, hazmat, for the link to the old thread. Someone remarked that the math is tough, but as I'm sure you know, it really isn't. I was calculating CG's before I got out of high school, and I'm no Einstein. More important is that you have good information.

I'm trying to think through a rather scary way to figure out how high my CG is from the ground. If I tip the tractor, say in a garage or somewhere safe, until it's just on the verge of tipping (i.e balanced on two wheels), the CG of the tractor is obviously above this point. Now I need the angle the axle makes with the ground, and I'm thinking use a digital camera or something to keep me from having to mess around under the machine. To be complete, of course, I'd need to tip it both left and right (just in case it's a little off center as well).

Tangential to the thread (my apologies), but I cant figure out how much I'm lowering my CG without knowing where it is in the first place.

If anyone out there has a set of scales and has the ability to measure the weight of one axle at a time, and one side at a time, you can find the horizontal (sideways, and lengthways) position of the cg. In order to find the vertial position, you have to have the ability to lift one axle at least 24 inches, and set it back down on the scale. The idea is knowing the level weight of both axles, the level and raised wheel base, and recording how much weight is transfered when you raise one end 24 inches, and plugging it into the formulas. If anyone is set up to measure this, let me know and i'll give more details.

With few exceptions, such as a homeowner who also uses the tractor to mow his lawn, or someone who hauls the tractor on a trailer of marginal capacity, any loader tractor should have loaded rear tires. In fact, many dealers will not sell a loader tractor without loading the rears. A balast box or heavy implement is nice in theory, but there is no guarantee that it will always be used. Also, stuff hanging off the back reduces the tractor's ability to get into tight spaces which loaded tires do not. Most compact tractors sold today have buckets of small enough capacity, that loaded rears alone provide sufficient rear ballast. Wheel weights are a viable option but cost more and do not provide as much stability on inclines because a partial liquid fill always lowers the CG vs fixed weights (liquid goes to the bottom, air to the top).

When I bought my tractor the dealer really didn't want to load the tires. He cited several problems with loaded tires like causing rim problems, I don't remember all of the details.

One of my first real jobs was working at a tire dealer and going out to fix tractor tires in the field. Almost all of them were loaded with some kind of chloride soloution that was nasty to work with. Growing up on the farm all of our tractors had loaded tires. Not sure what was up with the dealer I bought mine from

My dealer advised it but didn't push it at all. I told him I had a 900 lb rear weight and he was content. It was more of a discussion between two guys over what to do with the tractor than it was him saying I really needed to get the tires loaded or they wouldn't be responsible for my safety. This family has been selling tractors in all sizes for over 40 years, so apparently it works for them.

My dealer never said anything about loaded tires or ballast when I bought the tractor. I was a newbie. Found out that I needed ballast from TBN. Before delivery I asked about getting the tires loaded and he quoted me way too much... so I had him include a ballast box with the delivery.

About a year in, I started doing some digging for a project and realized that that the weight I had on the 3PT (~600 lb) was no where near enough. Not a pleasant feeling when your rear comes off the ground.

Around here no one has ever heard of loading with RimGuard. I let a local tire guy do the loading and he loaded with CaCl2 with tubes for a decent price.

I can't believe the difference in stability (that was last summer that I got this done)!. If I'm lifting something particularly heavy I tack on the ballast box as well. Lifted my new boxblade out of the truck it was delivered in - 700 or so lb and it was lifted high. Tractor lifted it like it was nothing.

I don't think that I will ever not have tires loaded. Maybe if I consistently had something like a heavy backhoe installed - I might consider it. Next time around though I would hope that RimGuard may have gotten a bit more popular around here so I could choose that. Realistically though, every body and his grandpa has been loading with CaCl2 around here - and often without tubes and there is no epidemic of rusted rims around here. Tire guy who loaded my tires advised me to proactively replace my valve stems in about 8 to 10 years to ensure that no leaks develop around there.

"Around here no one has ever heard of loading with RimGuard. I let a local tire guy do the loading and he loaded with CaCl2 with tubes for a decent price."

I was reading the specs for RimGuard and its only good to -35. Here in Minnesota we don't have many days in the -40 range but they do happen a couple times a year. Maybe thats why in some places its not common.

I'm pretty sure it would be just fine temp wise. We get no colder than you in Minnesota. New things just take time before they percolate up north through the border.

I know a Mahindra dealer up here who is thinking about becoming the distributer for RimGuard. Bet it will be up here and common in a few years.

I have a GC2300. I need to add weight to the rear as it is light when I load the fel. I use the tractor to mow my lawn I was told loaded tires will mess up the lawn (I have turf tires). Just wondering if I should load the rear tires or find an implement for the rear to add the weight.

EMS, I have a kubota B2620 with FEL, turf tires and a mid mower. I tried it without loading the tires but caused way too much damage to the grass because of spinning the tires. I had them loaded with RimGuard, 460#s for $144. No more spinning and does not damage the lawn unless I turn too sharp, which was also a problem when they weren't loaded.

I just got a M/F1531 at Northwood Power Equipment. They called me and loaded the tires with some biodegradeable material when they were working installing the backhoe. Hoe will be on most of time,except for york rake or rear blade. Landscapers here will also use some pulp or other material,so if they have a flat,the chemicals won't spill and ruin a customer's lawn. plowking
