Now, which liquid ballast you choose depends on how cold it gets where you live, how much your willing to spend, and what is available where you live. Those situations can be clustered in two main topics: - To prevent an unbalanced situation on the tractor, e. g. when working with a heavy front loader and adding ballast in the rear hitch or on the rear axle, or when using a front ballast as a counter weight for a heavy rear hitch. Rim Guard Tire Ballast needs to be filled to the 75% fill level in tires with the valve stem at 12:00. Tractor tire weight fluid. The static (no-load) weight distributions shown in Table 1 should be maintained by adding and removing ballast from the front and rear of the tractor. Since the day tractor manufacturers moved from steel wheel traction to tire on wheel configurations, farmers have added tractor tire fluids to their equipment to add traction weight, counterbalance and to lower their center of gravity to reduce the possibility of tipping.
Air pressure in the tractor tires also greatly affects soil compaction. The weight split should be 35-40% of the weight in the front, and 60-65% of the weight to the rear. The larger the tire size, the larger the contact area between tire and soil (desired), lower superficial soil compaction (desired) and lower power transmission (not desired) due to less lug penetration. Fluid in tractor tires chart. The minimum inflation pressure to carry the 15, 500 lbs. Only your agricultural tire expert is able to make a technical assessment and take a final decision, case by case. Soil type and soil condition.

For tubeless tyres: valve reference TR618A. And design (width, rim diameter and ratio), and is regulated by the TRA (Tire and Rim Association) in the US or the ETRTO (European Tire and Rim Technical Organization) in Europe. Chart 2 has the target weight splits, according to standard industry practices. To make the tractor heavier to transmit more force to the soil, e. for implements with lower working speed like a plow where the operational speed is less than 6 mph. It's not always a comfortable solution, because the movement of the mass of water in the front tyres produces a pendulum effect when driving and braking and could create a loss of steering control when cornering. You want to know everything about water ballasting your tractor tyres. To achieve maximum performance, ballasting and tire inflation must be considered. Most growers I deal with do prefer to be running in the 3% to 9% range. Pore space also allows roots to displace soil as they grow. And it weighs about the same per gallon as plain water. Transmitting that power requires large frictional forces, or traction, at the soil surface. Using the correct inflation pressure will ensure the best performance, largest footprint, best traction and lowest compaction. Generally speaking though, the tractor should be as least ballasted as possible, if the ballast is not really needed.
Improved traction resulting in time saving. From there, you can either screw the valve cap back on or, if you're currently using the tire, refill it to the desired pressure. Tractor Tire Water Ballast Weight Chart - TractorByNet. When all farm tires were bias-ply construction, choosing the right ballast -- in most cases, calcium chloride -- was easy. That often requires a little extra weight, which is called ballast. Ideally, the weight per horsepower ratio should be between 100 and 120 pounds/hp.
What are the benefits of water ballasting my tractor tyres? The formula for slip is as follows: percent slip = (loaded revolutions - no-load revolutions)100 x ________________________________________ loaded revolutions. Several optimum configurations may be determined for various types of field operations and soil types. How to Measure Slippage. Used full strength in tires, it provides freeze protection down to -20F and weighs about the same per gallon as water. Sometimes it's simpler to consider the quality of your tyres by opting for IF technology tyres, for example. They're no heavier than water. Bio-Ballast - Non-Corrosive Tractor Tire Ballast | NTS Tire Supply. At Michelin, we strongly encourage producers to work towards proper weight distribution of their machine. Optimum ballast is a compromise between wheel slip and rolling resistance. Liquid ballast tips.
A similar effect occurs when adding or removing ballast especially to the front weight bracket because it is not centered over the front axle. In fact, the pressure gauge ended up replacing the one on our pool pump. Unscrew the valve core, then attach one end of a tire hose to the core and one end to a water source, like your home water supply. This article has been viewed 68, 521 times. Loose or slippery residue can also cause high amounts of slip — even on otherwise firm soils. MFWD tractors should have 35% on the front and 65% on the rear axle. Generally, I like to fill a tire to 75%, or 140 gallons, with (the) solution. Tractor tire fluid capacity charter. " Combined with proper ballasting and knowledge of axle weight, proper inflation values can be extrapolated.
"In a common 75%-fill application, the ideal tire inflation pressure will be somewhere between 6 psi and 14 psi, enough to support the load on the (bias-ply) tires while allowing the farmer to complete his field work. Below the chart, the article covers pros and cons of each type. First of all, it is not suitable for rapid work if you are looking to save time on the installation of additional weight and it is even less suitable for travelling at speed on the road.

Calcium chloride was the go-to fluid for ages, but it's notorious for rusting wheels into oblivion. Ballasting through this method can be accomplished through cast discs that fit inside the tractor wheels or plastic shells filled with concrete or sand. Propylene Glycol is also used by veterinarians as a bypass sugar, administering it to ruminant animals such as cattle to perk them up. Determine the minimum tire inflation pressure listed in the chart for the weight supported by each tire, as calculated in Step 5. Lastly, it is also possible to resort to water ballasting because you just want to rebalance the axle opposite the implement's load distribution, by just filling up the front wheels if you have a lot of weight on the rear axle or inversely, by filling up the rear wheels if you are using a front loader, for example. Starting with water, we'll explore some of the different liquids used. The first critical factor is knowing the engine horsepower of the tractor and the axle weights. For a tractor to perform at its peak capabilities and efficiency, consider the following points. Fluid-filled tires also have a less "springy" feel due to the displaced air content. For a softer ride and better power hop control, a 40% fill rate at the four o'clock position should not be exceeded.
In most cases a tractor cannot be ballasted to the exact target weight outlined in Chart 2. What Options Are Available. 1Place a basin under the valve stem before removing liquid from the tire.

The lighter weights are more desirable and efficient as long as there are no performance issues such as stability or wheel hop.
You mix it into water and the solution resists freezing down to around -50°F.
