Best Grease for Tractor Loader

A tractor loader is a tractor equipped with a front-mounted bucket that can be hydraulically lifted, lowered, and angled forward and backward. It is pushed while digging by the tractor’s forward motion when withdrawn and swung by the tractor’s backing up and steering. Tractor loaders are typically used to load vehicles, excavate basements, and do bulldozer work. Additionally, they transfer materials over short distances.

When determining which grease is the best for tractors, it is necessary to evaluate all of the variables that a tractor must contend with. There are several greases available for the agricultural sector, but choosing the right grease will result in a significant ROI (return on investment). Considering the challenging economic scenario in which we find ourselves, farmers throughout the nation will want to exercise caution when selecting the sort of grease to use in their equipment. This decision has the potential to have a significant influence on their bottom line.

There are several greases available on the market, each with a different degree of quality and performance. It is necessary to do a thorough and critical examination of the performance of your present grease. How much grease was used in a calendar year? How much time have you spent lubricating your agricultural machinery? How many bearings were changed last year? Bushings, pins, and so forth? Consider the following: how effectively do you believe your existing grease protects your equipment?

There is always a superior product available, and grease is no exception. By examining the real performance history of your grease, you may drastically improve your maintenance situation by selecting the best grease for tractor loader.

Five Factors to Consider When Choosing the Best Grease for Tractor Loader

1. Capabilities in Extreme Pressure Conditions

Farm equipment, such as tractors, may be subjected to significant stress and strain as a result of severe pressure in a variety of applications, including shock loads, jolting, pounding, and vibrations. Grease may be pushed, hammered out, or shifted under these harsh working conditions. When grease is displaced or pounded out, the possibility of metal-on-metal contact exists, which may result in excessive wear and exposure to harmful substances such as dirt and water.

Under these extreme pressure circumstances, the optimum grease for tractors would be one that can resist the highest shock loads without being pounded out and also adheres tenaciously to the metal surface, acting as an armor-like barrier against any outside impurities. When looking for a grease that can withstand tremendous pressure, it’s a good idea to consult the grease manufacturer’s technical data sheet.

Look for the Timken OK Load Test, which is specified in pounds, on the data sheet. The industrial standard is ASTM D-2509. The Timken bearing company devised this industry standard test. Typical agricultural greases evaluated on the Timken OK Load Test generally have a Timken OK Load pound rating of 35 to 40.

If you’re a farmer trying to protect your equipment to the maximum extent feasible, there are superior severe pressure greases on the market. When searching for the finest tractor grease, it is necessary to turn to specialist custom lubricant suppliers. AMSOIL is one such business. AMSOIL’s Synthetic Polymeric Grease is a great high-performance grease for tractors. This grease is made using a proprietary over-based calcium-sulfonate complex thickener and a proprietary synthetic polymeric technique. This grease provides great protection against shock loads and heavy loads of any kind.

AMSOIL Synthetic Polymeric Grease passes the Timken OK Load Test with a score of 75+. AMSOIL’s synthetic grease has exceptional adhesion, or the ability to stick to metal surfaces. Additionally, it has extraordinary cohesion, or the capacity to attach to itself. These special qualities enable this grease to withstand tremendous pressure and pound out significantly more than other ordinary greases.

AMSOIL Synthetic Polymeric Grease beats the competition in high-pressure situations and stays in place longer than other greases. Additionally, AMSOIL Synthetic Polymeric Grease has a molybdenum disulfide content of 5%. Molybdenum is resistant to pressures of up to 500,000 pounds per square inch. The 5% moly content enables this grease to maintain a pressure of 75+ pounds during the Timken OK Load Test. When your tractors are subjected to intense pressure and stress loading conditions, using a lubricant containing 5% moly gives an additional layer of protection. It is the ideal grease for tractors due to its high resistance to intense pressure.

2. Resistance to Water

It is critical to understand the ramifications of operating agricultural equipment in damp areas. How does your grease defend itself against and react to moisture and water? Is grease being wiped away as a result of excessive equipment cleaning? Knowing how resistant your present grease has to water may aid in determining how well it performs in a wet environment. Is your excessive grease consumption the result of your grease’s incapacity to handle water? Are your greased equipment’s metal surfaces being exposed to pollutants needlessly as a result of grease being washed away by water? Is it necessary to lubricate your equipment more often than usual as a result of grease washout?

Using grease that is highly resistant to water washout has a direct effect on your maintenance schedule. It will affect the amount of downtime you experience and the amount of money you spend on damaged components caused by grease being rinsed away by water. There is a simple approach to determine the water resistance of your grease, and that is to study the technical data sheet provided by the grease manufacturer. The Water Washout Test, ASTM D-1264, is the industry standard for determining water washout.

When put through this test, the lubricant’s industry average for traditional greases designated as water resistant greases is between 5% and 10% water washout. If the working circumstances for your tractor and agricultural equipment include an excess of water, there are alternatives to the industry standard common water-resistant greases. AMSOIL’s Synthetic Polymeric Off Road Grease, for example, is a specialty grease that is exceptionally resistant to water. It passed the ASTM D-1264 Water Washout Test with a 1% water washout. This is five to ten times more effective than normal water-resistant grease.

A grease that is resistant to water washout will maintain a strong seal on the grease components, preventing moisture, water, and other potentially harmful pollutants from entering wear-prone regions.

When it comes to protecting your farm equipment from the detrimental effects of water and moisture, it is critical to pick the best grease for tractor loaders, particularly one that has been proved to be exceptionally resistant to water, such as AMSOIL Synthetic Polymeric Off Road Grease.

3. Reduction of Wear and Friction

Lubricating agricultural equipment is necessary for a variety of reasons. One of the most apparent is to avoid wear. Checking the grease manufacturer’s technical data sheet for its grade on the ASTM D-2266 Four Ball Wear Test is a good indication of a lubricant’s capacity to decrease friction and wear. The Four Ball Wear Test was developed to determine the amount of wear that may occur on a metal surface when it is greased and protected by a certain grease. The results of Four Ball Wear Tests are provided in millimeters (mm.) The industry standard for most conventional greases is between .65 and .90 millimeters of wear.

The objective of this test is to get the fewest possible wear marks. The lower the wear rating, the longer the life expectancy of the lubricated components. In the Four Ball Wear Scar Test, AMSOIL’s Synthetic Polymeric Off Road Grease scored less than .45 millimeters. Additionally, the same grease was run through the ASTM D-2596 Four Ball Wear Weld Point, which is measured in kilograms per square inch (kilograms of force.) It achieved a staggering 620+ KGF, which is unmatched in the industry.

Due to AMSOIL’s use of synthetic base stock oils with the same sized molecules in their chemical structure, the base oil reduces friction. AMSOIL chemists include the best friction modifiers, anti-wear additives, and EP agents into the synthetic base oils, coupled with 5% molybdenum disulfide. The basic oil and the proprietary additive package work in synergy to protect all metal surfaces against friction, wear, and any high-pressure loads to which they may be subjected. When it comes to minimizing friction and wear on tractors, AMSOIL has really designed the greatest grease.

4. High Operating Temperature Range

Typical agricultural equipment greases have a melting point of between 290 and 390 degrees Fahrenheit. They operate at a maximum temperature of between mid-200 and low-300 degrees Fahrenheit. Throughout the hot summer months, farm tractors have been driven hard and long, and these challenging/hot situations may and will expose agricultural equipment to significantly higher ambient temperatures.

When equipment is subjected to prolonged operation at elevated ambient temperatures, traditional greases may thin and begin to degrade. When a typical grease is pushed to its limits, there is very little tolerance for error, and the grease’s performance begins to deteriorate. As the oils in the grease decay, some of its protective properties against severe pressure or Timken OK Load may begin to deteriorate.

As the grease degrades, it may also deteriorate the grease’s capacity to repel water. Choosing the best grease for tractor loaders entails selecting a grease that provides an extremely broad and robust safety net of performance in terms of its capacity to withstand high temperatures. Conventional greases do not provide this level of protection for the farmer or his equipment. What temperature range qualifies as a high-temperature grease? AMSOIL Synthetic Polymeric Off Road Grease is one such grease to consider.

To determine its resistance to severe heat, it was subjected to the ASTM D-2265 Dropping Point Test. AMSOIL grease has a melting point of 650 degrees Fahrenheit. This provides a very extensive safety net for farmers in the event that their equipment is compelled to function in exceptionally hot temperatures.

This is a superb grade, and it is quite improbable that many other greases in the agriculture market can compete with this sort of dropping point. AMSOIL’s Synthetic Polymeric Off Road Grease is distinguished by its balanced chemistry and ability to achieve top ratings in a variety of tests.

Most traditional greases may perform well on just one of a variety of tests. For instance, they may be a high-temperature grease yet have weak EP and water washout properties. On the other hand, AMSOIL engineers its greases to perform far better than average in all of the critical areas that grease for agricultural machinery must address.

Having a grease that is balanced across all performance characteristics distinguishes it as the best tractor grease.

5. Extended Service Life

For agricultural operations that rely on their equipment being in the field for lengthy periods of time with little downtime, it is critical to carefully choose a heavy-duty grease that provides severe duty performance and extended service intervals. This eliminates the need for traditional greases. It must withstand tremendous pressure pounding and unquestionably be capable of drastically reducing the amount of grease discharged when subjected to continual shock loads and pounding action. AMSOIL Synthetic Polymeric Off Road Grease is the ideal grease for tractors owing to its improved capabilities of extending service intervals and significantly lowering grease use.

It has been shown in real-world field testing that it is capable of reducing grease usage by up to 50%. This enables the farmer to continue with its present maintenance routine while using less grease in each application. Additionally, it may lengthen the period between re-greasing intervals.

By resisting shock loads, extending service intervals, and providing incredible protection, you may save money on equipment replacement, labor, and lubrication.
