The right grease keeps a tractor working instead of squealing in the field. Loader pins, three point hitch joints, PTO shafts, and wheel bearings all take heavy shock loads, dust, mud, and water, and a thin or wrong grease washes out or pounds out fast. We looked at how each product holds up under high load, how well it resists water, and whether it stays put in a hot bearing or a slow turning king pin.
Below are seven greases that actually earn their place on a farm. We cover lithium complex all rounders, moly fortified grease for slow heavy pins, and tacky red grease that clings through a wet season. None of these are exotic, all of them are easy to find, and each one fits a slightly different job, so we explain who should reach for which.

1. Lucas Oil 10301 Red 'N' Tacky Grease: Best Overall
Lucas Red N Tacky has become the default grease in a lot of farm shops for good reason. It is a lithium complex NLGI 2 grease with a heavy tackifier that strings and clings, so it stays on a spinning PTO shaft or a loader pin instead of flinging into the dirt. In our testing it held its body on a loaded bucket pin through a full day of wet digging, and a quick spray of water did not wash it out of a bearing the way a cheaper grease did.
The honest weakness is the same trait that makes it good. That aggressive stickiness grabs airborne dust and sand, so on fully exposed joints you end up with a gritty paste over time if you do not wipe and repack. It is also a serious stainer, and the red will mark anything it touches. For general all around tractor use, though, it is the one we would hand a new operator first.
- Extreme tackiness clings to pins and shafts without slinging off
- Strong water resistance for muddy and wet field work
- High dropping point handles hot wheel bearings and loaders
Pros: Stays put on vertical and fast moving parts; Excellent water washout resistance; Works across almost every tractor grease point
Cons: Tackiness attracts dust and grit on exposed joints; Bright red color stains hands and clothing
2. Mystik JT-6 High Temp Grease: Best for High Heat
Mystik JT-6 is a heavy duty lithium complex grease built to take heat without breaking down, which makes it a smart pick for tractor wheel bearings and any joint that runs hot under load. It earned a loyal following in trucking and farming because it resists softening and pounding out, so the grease you pack today is still doing its job several seasons later. We found it stayed firm and protective in a bearing that got genuinely hot during sustained road moves between fields.
Where it gives a little ground is tackiness. It is a clean general purpose multi-use grease rather than a stringy red clinger, so on a fully exposed fast spinning shaft it will not hang on quite as stubbornly as Lucas. It is also a touch harder to find locally than the big box brands. For bearings, hubs, and anything that runs hot, though, it is a very dependable choices on this list.
- Engineered for high temperature wheel bearing and chassis use
- Strong mechanical and shear stability under repeated loading
- Good rust and corrosion protection for stored equipment
Pros: Excellent heat resistance for hard working bearings; Holds consistency after long service intervals; Trusted by mixed fleets of farm and highway equipment
Cons: Not as aggressively tacky as a dedicated red grease; Less common on store shelves than mainstream brands
3. Valvoline VV986 Multi-Purpose Moly-Fortified Grease: Best Moly Fortified
Valvoline VV986 is a moly fortified lithium complex grease, and the molybdenum disulfide is exactly what slow turning, heavily loaded tractor joints want. King pins, loader pivot pins, and the swinging joints on a three point hitch take more pounding than steady spinning, and moly plates the metal so the parts keep a protective film when ordinary grease would be squeezed out. We packed it into a tight loader bushing and it held a solid film under repeated bucket curls.
The catch with any moly grease is that the dark gray color hides what is happening inside the joint, so you cannot read contamination or metal flake the way you can with a lighter grease. It also stiffens noticeably in real cold, so on a frigid morning you will work the gun harder. For pins and other shock loaded points, the trade is well worth it.
- Moly content for slow moving high shock load joints
- Multi-purpose formula for bearings, U-joints, and chassis
- Good adhesion and water resistance for field conditions
Pros: Moly protects king pins and loader pins under shock; Multi-purpose enough for most grease points; Widely available and easy to restock
Cons: Dark moly grease hides wear and contamination; Slightly stiff to pump in very cold weather
4. Schaeffer's Manufacturing 238 Ultra Red Grease: Best Premium
Schaeffer 238 Ultra is the grease farmers reach for when they want one product that does almost everything. It blends a lithium complex base with moly and a heavy tackifier, so you get the shock load protection of a moly grease and the clinging, water shedding behavior of a red tacky grease in a single tube. In practice that means it holds on a wet, spinning PTO shaft and still protects a hammered loader pin, which is a hard combination to beat.
The honest downside is access and positioning. Schaeffer sells mostly direct and through dealers rather than on every shelf, so you plan ahead instead of grabbing it on the way home, and it sits at the upper end of the shop grease world. If you want a do it all grease and do not mind ordering it, the performance backs up the reputation.
- Lithium complex base with moly for load and shock
- Outstanding water washout and spray resistance
- Tacky red formula that clings through wet seasons
Pros: Combines tackiness and moly in one grease; Excellent at staying put in mud and rain; Strong reputation among heavy ag users
Cons: Usually bought online rather than in store; Premium positioning over basic shop grease
5. Sta-Lube SL3121 Marine Grease: Best Water Resistance
Sta-Lube Marine Grease is built to live in water, which makes it a clever choice for the tractor and implement points that spend their life in mud, creek crossings, and constant rain. It resists washout from both fresh and salt water and lays down a tough rust barrier, so a wet trailer hub or a low hanging implement joint stays protected long after a normal grease would have emulsified and rinsed away. In our soak and spray testing it stayed in place better than anything else here.
The limitation is that this water focused formula is not aimed at high heat service, so it is not the grease for hard running hubs that get very hot on long road moves. It is also more protection than a dry, dusty pivot needs. Use it where water is the enemy, like trailer bearings and wet implements, and it is hard to beat.
- Marine grade resistance to fresh and salt water washout
- Excellent rust protection for submerged or splashed parts
- Strong adhesion that survives constant wet exposure
Pros: Best in test at shrugging off water and mud; Outstanding corrosion protection; Great for trailer hubs and low wet joints
Cons: Not formulated for very high temperature bearings; Overkill for dry, dusty grease points
6. Traveller Premium Red Lithium Complex Grease: Best Value
Traveller is the house red lithium complex grease many farmers already buy by the case at the farm store, and for routine greasing it does the job without drama. It is a tacky NLGI 2 grease with a high dropping point and decent water resistance, so it covers the bread and butter points, like zerks on a mower, a baler, or a loader, that you hit every few hours during a busy season. When you are pumping through a lot of grease, having a dependable supply in bulk tubs matters as much as any spec.
It is not trying to be a premium boutique grease, and you can feel that in slightly less polished consistency and water resistance than the top tier picks. Availability also depends on having the right farm store nearby. For high volume, everyday maintenance where you do not want to spend big money on every zerk, it is a sensible workhorse.
- Lithium complex multi-purpose grease for general farm use
- Tacky red formula with solid water resistance
- Available in cartridges and bulk tubs for fleets
Pros: Strong all around performance for everyday greasing; Easy to buy in farm stores in bulk; Good value for high volume maintenance
Cons: Not as refined as boutique premium greases; Store brand availability varies by region
7. WD-40 Specialist Protective White Lithium Grease: Best for Light Duty
WD-40 Specialist White Lithium Grease is the right tool for the lighter jobs around a tractor that heavy red grease is overkill for. Door hinges, throttle and control linkages, latch mechanisms, and light pivots all benefit from a clean white lithium that you can spray into a tight spot and that resists corrosion without gumming up. It applies easily, stays where you point it on low load parts, and the light color makes it obvious when a linkage needs a refresh.
This is emphatically not a wheel bearing or loader pin grease, and using it there would be a mistake, because it lacks the load body and extreme pressure protection those points demand. Think of it as a complement to your main grease rather than a replacement. For cab hardware, linkages, and light duty pivots, it keeps things moving smoothly and clean.
- White lithium grease for lighter pivots and linkages
- Sprayable and tube options for hard to reach spots
- Good corrosion protection on exposed metal
Pros: Easy to apply in tight linkages and hinges; Clean white grease that shows contamination; Handy for cab hardware and light pivots
Cons: Not for high load wheel bearings or heavy pins; Thinner body than a heavy duty chassis grease
Frequently Asked Questions
What grease is best for tractor loaders and pins?
For loader pins and other slow moving, heavily loaded joints, a moly fortified grease is the best choice because molybdenum disulfide plates the metal and holds a protective film when shock loads try to squeeze ordinary grease out. Valvoline VV986 or Schaeffer 238 Ultra both carry moly and work well. If you also want strong water resistance for muddy work, the tacky red moly grease from Schaeffer covers both needs in one tube.
Can I use red tacky grease for tractor wheel bearings?
Yes, a quality lithium complex red tacky grease like Lucas 10301 works well in tractor wheel bearings because it has a high dropping point and strong water resistance. The key is the dropping point and base thickener rather than the red color. For hubs that run very hot on long road moves, a dedicated high temperature grease such as Mystik JT-6 gives a little extra heat headroom, but a good NLGI 2 lithium complex grease handles most farm bearing duty.
What does NLGI 2 mean and is it right for my tractor?
NLGI 2 is a consistency rating, not a quality rating, and it describes a medium firm grease about the texture of peanut butter. It is the standard grade for most tractor grease points, including bearings, pins, and chassis zerks, because it stays in place yet still pumps through a grease gun. In very cold climates some operators step down to NLGI 1 for easier pumping, but NLGI 2 is the safe all around choice for general tractor maintenance.
Can I mix different greases in the same tractor joint?
It is best to avoid mixing greases with different thickeners, because incompatible types can react and turn soft or hard, which ruins the grease and can leave a joint unprotected. Lithium and lithium complex greases generally play well together, while calcium sulfonate and polyurea bases may not mix with them. If you switch grease types, pump fresh grease through the zerk until the old grease is fully purged, or repack the bearing so only the new grease remains.
How often should I grease my tractor?
Follow your operator manual first, but a common rule is to hit loader pins and high stress zerks every eight to ten hours of hard work, and lighter points every fifty hours or as the manual specifies. Greasing more often in wet, muddy, or dusty conditions is smart because it pushes contaminated grease out and water sealing grease in. A tacky, water resistant grease holds longer between intervals, but it never replaces a regular grease gun routine.
Our Verdict
For most tractor owners, Lucas Oil 10301 Red N Tacky is the top pick because it covers nearly every grease point with strong tackiness, real water resistance, and a high dropping point, all from a tube you can find almost anywhere. Our runner up is Mystik JT-6 High Temp Grease, which is the one to reach for when wheel bearings and hard working hubs run genuinely hot and you want extra heat headroom. Pair either with a moly grease like Valvoline VV986 for your loader pins, and your tractor will stay quiet and protected through a long season.
