JDQ6068 Severe Off-Road Dyno Engine Test
In the development of Plus-50 II, John Deere engineers tested the oil under the most extreme conditions using this severe dyno test. The severe dyno test is a John Deere engine that runs at full load and high heat to thoroughly test the capabilities of the oil. At the end of the test, we evaluate the engine parts and the oil to determine how well the oil protects the engine and how long it will last under such extreme conditions.
Pistons from the Severe Off-Road Dyno Engine Test
Competitive oil leaves spot and more piston deposits in the piston and groove area and the under crown area of the piston which can cause the rings to not perform as designed. Plus-50 II formulated for hotter off-road conditions to reduce piston deposits so the engine will perform optimally for a long time.
Minimises Piston and Deposited Formulation
- Help reduce high friction and wear
- Help prevent excessive oil consumption and blowby
- Increase engine performance
CK-4 Minimum Engine Tests
In addition to our own extensive testing, we also participate with engine tests that define the minimum requirements of API CK-4 oil. These graphs demonstrate the magnitude of performance Plus-50 II has when compared to these minimum specifications. Note that lower is better.

Evolution of Hy-Gard
60 years of continuous development makes Hy-Gard the most advanced tractor hydraulic fluid in the world!
| John Deere develops first THF standard, JD303 | JDM J14B replaces JD303 | JDM J20A replaces J14B | RES 10060 written, exclusive additive package adopted | JDM J20C replaces J20A | Hy-Gard additive package upgraded | Continuous improvement |
JDM J20C
An industry classification for Transmission Hydraulic Fluid (THF) does not exist. Each manufacturer establishes a minimum requirement that oils must meet for use in their equipment. John Deere has established the JDM J20 specification for minimum THF performance. John Deere does not monitor competitive or "will-fit" oils, or approve JDM J20 oils. While claiming to meet John Deere requirements, it is possible that the competitive or "will-fit" oils do not meet even the minimum performance requirements for John Deere machines, which could result in premature failures.
John Deere Hy-Gard exceed the performance of their JDM J20 specification counterparts. The performance requirements for our family of Hy-Gard products are higher, and many extra performance tests are mandatory.
| Wet Clutch Test | |
|
|  Customers can expect better clutch performance (smoother equipment, less slippage, and reduced wear) when using John Deere HyGard™ Transmission and Hydraulic Oil. |
| TZT Oxidation Test | |
|
| The difference in performance of Hy-Gard and a competitor's oil. The competitor oil has left heavy deposits on the pan and the viscosity has increased dramatically. This can cause valve sticking and the oil may be corrosive. Hy-Gard parts look like new, it leaves no sludge of deposits for longer equipment life. Test runs:

| Gear Test | |
|
|
Wear in the JDQ 95B final drive test with Hy-Gard was shown to be less than the wear of a minimum performance JDM J20C fluid. |
| Slow-Cool Fluidity Test | |
|
| Hy-Gard is checked for proper viscosities using the slow-cool fluidity test in addition to industry-standard tests. The slow-cool fluidity test (developed by John Deere engineers and recognised by the oil industry as a valid testing procedure) ensures Hy-Gard's proper viscosity performance, which reduces downtime and lowers the cost of operation. Few competitive hydraulic transmission oils are tested for this type of low-temperature viscosity performance. Oil needs to flow properly at low temperature to ensure lubricant gets to where it is needed. The cold temperature flow of Hy-Gard can be much better than oils that claim they meet JDM J20C (tested after aging). |
| Air Temperature Chart | |
|
| Use the oil viscosity based on the expected air-temperature range during the period between changes. Always check the Operator's Manual for specific applications. Some applications may be restricted at the upper or lower limits of the temperature range. |
| Wet Brake Test | |
|
| Customers can expect better brake-chatter control using John Deere Hy-Gard compared to oils meeting the minimum performance JDM J20 specification. |
